Toaster is a web interface to the Yocto Project's OpenEmbedded build system. The interface enables you to configure and run your builds. Information about builds is collected and stored in a database. You can use Toaster to configure and start builds on multiple remote build servers.
This release of Toaster does allow you to configure and initiate builds. However, you cannot use Toaster to customize image recipes, which still must either be done by hand or through Hob. As Toaster matures, it eventually will equal and surpass Hob functionality, at which time Hob will be deprecated.
For more information on Hob, see the "Image Development Using Hob" section in the Yocto Project Development Manual.
You can use Toaster in Analysis Mode or Build Mode:
Analysis Mode:
In Analysis Mode, you can record builds and statistics.
In this Mode, you directly access the
bitbake
command, which you then use to
build images.
Analysis Mode requires you to have first started
Toaster and then to initiate your build using the
bitbake
command from the shell.
Toaster must be started before the build or it will not
collect build data.
Toaster has the following capabilities in Analysis Mode:
See what was built (recipes and packages) and what packages were installed into your final image.
Browse the directory structure of your image.
See the value of all variables in your build configuration, and which files set each value.
Examine error, warning and trace messages to aid in debugging.
See information about the BitBake tasks executed and reused during your build, including those that used shared state.
See dependency relationships between recipes, packages and tasks
See performance information such as build time, task time, CPU usage, and disk I/O.
Build Mode:
In Build Mode, Toaster handles the build configuration,
scheduling and execution.
In this mode, all your interaction with the build system
happens through the web interface.
You do not have direct access to the
bitbake
command.
Using this mode, you configure and start your builds within Toaster's GUI. Each project can be configured for a specific version of the build system. As shipped, Toaster supports Yocto Project Releases 1.7 and beyond.
Toaster has all the same capabilities in Build Mode as it does in Analysis Mode plus the following:
Browse layers listed in the various layer sources that are available in your project (e.g. the OpenEmbedded Metadata Index at http://layers.openembedded.org/layerindex/).
Import your own layers for building.
Add and remove layers from your configuration.
Set configuration variables.
Select a target or multiple targets to build.
Start your builds.
You can set Toaster up to run as a local instance or as a shared hosted service. Regardless of how you set up Toaster, both Analysis and Build Modes are available.
When Toaster is set up as a local instance, all the components reside on a single build host. Fundamentally, a local instance of Toaster is suited for a single user developing on a single build host.
Toaster as a hosted service is suited for multiple users developing across several build hosts. When Toaster is set up as a hosted service, its components can be spread across several machines:
Table of Contents
This chapter describes how you need to prepare your system in order to use Toaster.
You first need to be sure your build system is set up to run the Yocto Project. See the "Setting Up to Use the Yocto Project" section in the Yocto Project Quick Start for information on how to set up your system for the Yocto Project.
Toaster requires extra Python dependencies in order to run.
A Toaster requirements file named
toaster-requirements.txt
defines the
Python dependencies.
The requirements file is located in the
bitbake
directory, which is located in the
root directory of the
Source Directory
(e.g. poky/bitbake/toaster-requirements.txt
).
The dependencies appear in a pip
,
install-compatible format.
It is highly recommended that you use a Python virtual environment that allows you to maintain a dedicated Python executable and its own set of installed modules. Doing so separates the executable from the Python and modules provided by the operating system and therefore avoids any version conflicts.
Follow these steps to set up your virtual environment. These steps assume a Ubuntu distribution:
Install virtualenv
:
Install the supported
python-virtualenv
package from your
distribution rather than using pip
.
$ sudo apt-get install python-virtualenv
Create and Activate a Virtual Environment:
$ virtualenv venv $ source venv/bin/activate
$ source venv/bin/activate
You need to install the packages that Toaster requires. Use this command:
$ pip install -r bitbake/toaster-requirements.txt
Table of Contents
This section describes how to use Toaster in Analysis Mode after setting Toaster up as a local instance or as a hosted service.
Follow these steps to set up a local instance of Toaster and then run in Analysis Mode:
Prepare your Build System: Be sure your system has the Toaster requirements by following the steps in the "Establishing Toaster System Dependencies" section.
Get Set Up to Use the Yocto Project: Get the requirements set up so that you can use the Yocto Project to build images. See the "Setting Up to Use the Yocto Project" section in the Yocto Project Quick Start for information.
Source your Build Environment Setup Script:
From your
Source Directory
(e.g. poky/build
), source the build
environment setup script
oe-init-build-env
or
oe-init-build-env-memres
.
Start Toaster: From the Build Directory, start Toaster:
$ source toaster start
Start Your Build Using BitBake:
Use the bitbake
command to start your
build.
Here is an example that builds the
core-image-minimal
image:
$ bitbake core-image-minimal
Open Your Browser:
Open your browser and visit
http://host:port/toastergui
.
For host and port values, see the output of the
source toaster start
command.
For information on how to use Toaster, see the
"Using the Toaster Web Interface"
section.
A hosted service resides on a shared server and allows multiple users to take advantage of Toaster.
In a production environment, you might want to have multiple local instances of the Toaster Logging Interface running on various remote build machines, and have those local instances access and use a single web server. To do this, you need to do the following:
Maintain a common SQL database.
Set up separate instances of BitBake servers and Toaster Logging Interfaces for each of those separate BitBake servers.
The common SQL database allows the Web server to show data from all the various BitBake builds. Setting the SQL database outside of any Build Directory maintains a separation between the various builds. The BitBake servers, the SQL server, and the Web server or servers can be run on separate machines.
Follow these steps to set up and run a hosted service and run Toaster in Analysis Mode:
/opt/bitbake/
.
Prepare your Build System: Be sure your system has the Toaster requirements by following the steps in the "Establishing Toaster System Dependencies" section.
Get Set Up to Use the Yocto Project: Get the requirements set up so that you can use the Yocto Project to build images. See the "Setting Up to Use the Yocto Project" section in the Yocto Project Quick Start for information.
Install and Set up the Database Server:
You can use any SQL server out of the box.
It is recommended that you use
mysql-server
because it has
the advantages of advanced SQL features along with a
fast and reliable database.
However, setting up mysql-server
is more complex and might require a Database
Administrator to tune it.
Another supported database backend is
sqlite3
.
With sqlite3
, you have the
advantage of no configuration and an easy installation.
However, Toaster still requires direct access to the
backend.
The sqlite
backend is also slower
as compared to mysql-server
, and
has no transactional support.
You should set up proper username and password
access on the shared database for everyone that will
be using Toaster.
You need administrator rights for the root account,
which is not the same thing as root access on the
machine.
Here is an example that installs
mysql-server
and sets up
some user accounts and the database.
$ apt-get install mysql-server $ mysql -u root mysql> CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password'; mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; mysql> CREATE DATABASE 'toaster';
You need a separate clone of the Source Repositories for the Database Server. This clone is only used for getting the latest Toaster files. You can set this up using the following Git command. Be sure to set up the directory outside of any Build Directories.
$ git clone git://git.yoctoproject.org/poky
In the separately cloned tree for the Database Server,
edit the
bitbake/lib/toaster/toastermain/settings.py
file so that the DATABASES
value
points to the previously created database server.
Use the username and password established
earlier.
Here is an example:
$ cat /opt/bitbake/lib/toaster/toastermain/settings.py ... DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'toaster', 'USER': 'newuser', 'PASSWORD': 'password', 'HOST': '192.168.0.25', 'PORT': '3306', } ...
Install and Set Up the Web Server:
For a production environment, it is recommended that
you install and set up a front-end web server.
This server allows for load balancing and
multi-threading over Toaster and
django
WSGI.
Here is an example that uses Apache web server.
$ apt-get install apache2 libapache2-mod-wsgi $ a2enmod wsgi $ cat /etc/apache2/sites-available/000-default.conf ... # the WSGIPythonPath is global WSGIPythonPath /opt/bitbake/lib/toaster/ ... #snip - in VirtualHost WSGIScriptAlias / /opt/bitbake/lib/toaster/toastermain/wsgi.py <Directory //opt/bitbake/lib/toaster/toastermain/> <Files wsgi.py> Require all granted </Files> </Directory> ...
You need to collect static media from Toaster and continue configuring Apache to serve that static media:
$ mkdir /var/www.html/static && cd /var/www.html/static $ /opt/bitbake/lib/toaster/manage.py collectstatic $ cat /etc/apache2/sites-available/000-default.conf ... # in VirtualHost, AHEAD of the WSGIScriptAlias definition Alias /static/ /var/www.html/static/ <Directory /var/www.html/static/> Require all granted </Directory> ... WSGIScript Alias / /opt/bitbake/lib/toaster/toastermain/wsgi.py ...
Start Toaster: Synchronize the databases for toaster, and then start up the web server. Here is an example that continues with the assumed components from the previous steps:
$ /opt/bitbake/lib/toaster/manage.py syncdb $ /opt/bitbake/lib/toaster/manage.py migrate orm $ /opt/bitbake/lib/toaster/manage.py migrate bldcontrol $ service apache2 restart
You can find general documentation on
manage.py
at the
Django
site.
For reference information on Toaster-specific
manage.py
commands,
see the
"Useful Commands"
section.
Enable Build Logging to the Common SQL Server for Each Build Directory you are Using:
You need to make sure that the
toaster
class and build history are enabled.
This is done in a
toaster.conf
file that is
created automatically by the toaster
start
command,
and that lives inside the
Build Directory
in /conf/toaster.conf
.
That file should include the following line:
INHERIT += "toaster buildhistory"
For information on build history, see the "Maintaining Build Output Quality" section in the Yocto Project Development Manual.
You also need to point to the database that you set
up in step 3.
You can do this by exporting the DATABASE_URL
variable as follows:
export DATABASE_URL=mysql://newuser:password@192.168.0.25:3306/toaster
This example assumes that you are using
mysql-server
.
The IP address should be the IP address of your
database server.
Source your Build Environment Setup Script:
From your
Source Directory
on each of the build systems,
(e.g. poky/build
), source the
build environment setup script (i.e.
oe-init-build-env
or
oe-init-build-env-memres
).
Start the BitBake Server: Start the BitBake server using the following command:
$ bitbake --postread conf/toaster.conf --server-only -t xmlrpc -B localhost:0 && export BBSERVER=localhost:-1
Start the Logging Server: Start the Toaster Logging Interface using the following command:
$ nohup bitbake --observe-only -u toasterui >toaster_ui.log &
autodiscovery
for BitBake
ports.
Doing so prevents collisions.
Start Builds Using BitBake:
Use the bitbake
command to start a
build on a build system.
Here is an example that builds the
core-image-minimal
image:
$ bitbake core-image-minimal
When you are finished with a build in a given
Build Directory, be sure to kill
the BitBake server for that build area:
$ bitbake -m
For information on how to use the Toaster web interface, see the "Using the Toaster Web Interface" section.
This section describes how to use Toaster in Build Mode after setting Toaster up as a local instance or as a hosted service.
Follow these steps to set up a local instance of Toaster and then run in Build Mode:
Prepare your Build System: Be sure your system has the Toaster requirements by following the steps in the "Establishing Toaster System Dependencies" section.
Get Set Up to Use the Yocto Project: Get the requirements set up so that you can use the Yocto Project to build images. See the "Setting Up to Use the Yocto Project" section in the Yocto Project Quick Start for information.
Start Toaster:
From the root of the source directory (e.g
poky/
), run the following command:
$ bitbake/bin/toaster
Create a Superuser: Django will ask you if you want to create a superuser. You can skip this step, but it is recommended that you create a superuser. You can use the superuser to access the Django administration interface and make changes to the Toaster configuration.
Select the Build Log Directory: Toaster asks you to specify the directory where you want to store the build log files. Choosing a directory for these files makes sure they are always available to you. If you do not choose a directory, the logs can disappear (e.g. deleting the Build Directory).
When Toaster prompts you for the Build Log directory, you can select the suggested default or provide a path to a different directory.
Specify the Layer Checkout Directory: Toaster asks you to specify the directory into which layers are checked out. Toaster clones any layers needed for your builds inside this directory.
When Toaster prompts you for the Layer checkout directory, you can select the suggested default or provide a path to a different directory.
Specify the Build Directory Path: Toaster asks you to specify the path to the Build Directory. You can select the suggested default or provide a path to a different directory.
Choose Whether or not to Import a Default Toaster Configuration File:
Toaster asks you if you want to import a default
Toaster configuration file.
Toaster configurations are stored in
JSON files called
toasterconf.json
.
For information on JSON files, see the
"JSON Files"
section.
You can skip importing a configuration file by entering "0" at the prompt. However, it is recommended that you import one of the configuration files listed during this step. You can always amend the imported configuration during a later stage through the Django administration interface.
For general information on Django, see the
available
documentation.
You can also find information on Toaster-specific
manage.py
commands in the
"Useful Commands"
section.
Open the Browser: If no browser window appears, open your favorite browser and enter the following:
http://localhost:8000/toastergui
You can now use the Toaster web interface.
Follow these steps to set up a hosted service and run Toaster in Build Mode:
Prepare your Build System: Be sure your system has the Toaster requirements by following the steps in the "Establishing Toaster System Dependencies" section.
Get Set Up to Use the Yocto Project: Get the requirements set up so that you can use the Yocto Project to build images. See the "Setting Up to Use the Yocto Project" section in the Yocto Project Quick Start for information.
Be Sure Management is Enabled:
If you are running Toaster under Apache, you need to
be sure management is enabled.
To enable management, set
MANAGED
to "True" by adding
the following to the
bitbake/lib/toaster/settings.py
file:
MANAGED="True"
Set Up Toaster for Normal Usage: You need to configure each build environment, layer sources, and BitBake versions.
Verify that your releases have been loaded correctly by using the Toaster web interface to create a new project. Check the "Releases" dropdown menu to be sure your newly specified releases exist.
If you want to use the administration interface for this step, here is a set of example commands with some descriptions as an example:
# Create the user under which the builds will run
$ adduser poky
# Bring up the administration interface
$xdg-open http://server-address
/admin/
# Login with the admin user previously created
# Go to the BuildEnvironment object in Build Environments and
# set address to local host, sourcedir to /home/poky, and
# builddir to /home/pokybuild.
#
# Save your changes and exit
# Go to Home, Layer Sources and select add Layer Source
# Name: OpenEmbedded, Sourcetype: layerindex,
# Apiurl: http://layers openembedded.org/layerindex/api/
# Save your changes and exit
# Go to Home, Bitbake Versions, Add bitbake version;
# Take version information from: http://git.openembedded.org/bitbake/refs/heads,
# This example assumes "master" version.
# set Name: master, Giturl git://git.openembedded.org/bitbake
# branch master, dirpath /
# Save your changes and exit
You also need to configure the project releases, the default variables, and update information from the layer index. Continuing with the example:
# Go to Home, Releases, Add release # set Name: master, Description: Current master release, select Bitbake Version, # and Branch: master # Save your changes and exit # Go to Home, Toaster Settings, select the Setting for DEFAULT_RELEASE # set Helptext: This selects the default release., Value: master # Save your changes and exit # Go to Home, Bitbake Versions, Add bitbake version; # take version information from : http://git.openembedded.org/bitbake/refs/heads, # this manual assumes the master version # set Name: master, Giturl git://git.openembedded.org/bitbake # branch master, dirpath / # Save your changes and exit # Update the information # bitbake/lib/toaster/manage.py lsupdates
For reference information on Toaster-specific
manage.py
commands, see the
"Useful Commands"
section.
Install and Set up the Database Server:
You can use any SQL server out of the box.
It is recommended that you use
mysql-server
because it has
the advantages of advanced SQL features along with a
fast and reliable database.
However, setting up mysql-server
is more complex and might require a Database
Administrator to tune it.
Another supported database backend is
sqlite3
.
With sqlite3
, you have the
advantage of no configuration and an easy installation.
However, Toaster still requires direct access to the
backend.
The sqlite
backend is also slower
as compared to mysql-server
, and
has no transactional support.
You should set up proper username and password
access on the shared database for everyone that will
be using Toaster.
You need administrator rights for the root account,
which is not the same thing as root access on the
machine.
Here is an example that installs
mysql-server
and sets up
some user accounts and the database.
$ apt-get install mysql-server $ mysql -u root mysql> CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password'; mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; mysql> GRANT ALL PRIVILEGES ON * . * TO 'newuser'@'localhost'; mysql> CREATE DATABASE 'toaster';
You need a separate clone of the Source Repositories for the Database Server. This clone is only used for getting the latest Toaster files. You can set this up using the following Git command. Be sure to set up the directory outside of any Build Directories.
$ git clone git://git.yoctoproject.org/poky
In the separately cloned tree for the Database Server,
edit the
bitbake/lib/toaster/toastermain/settings.py
file so that the DATABASES
value
points to the previously created database server.
Use the username and password established
earlier.
Here is an example:
$ cat /opt/bitbake/lib/toaster/toastermain/settings.py ... DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'toaster', 'USER': 'newuser', 'PASSWORD': 'password', 'HOST': '192.168.0.25', 'PORT': '3306', } ...
Create the Database Use the following commands to create the default database structure:
$ bitbake/lib/toaster/manage.py syncdb $ bitbake/lib/toaster/manage.py migrate orm $ bitbake/lib/toaster/manage.py migrate bldcontrol
The interface asks you if you want to create a superuser. Do not skip this step. You will use the superuser account to access the administration interface and make changes to the Toaster configuration.
Select Where the Build Process Takes Place: You need to create three directories for storing build artifacts, downloading sources, and running builds. All three directories need to be writable by the user, which is "poky" in this example. The build artifacts directory needs to readable by the apache user. You also need free disk space in the range of 100 Gbytes. Following are three suggested directories:
/home/poky/buildartifacts/ /home/poky/build/ /home/poky/sources/
Set Up the toasterconf.json
File:
Download the hosted toasterconf.json
file
from the Yocto Project wiki and edit it to suit your
environment.
For information on the relevant sections of the file,
see the
"JSON Files"
section.
After editing the file, load it by running the following:
$ bitbake/lib/toaster/manage.py loadconf path-to-toasterconf.json-file
For reference information on Toaster-specific
manage.py
, see the
"Useful Commands"
section.
Check the Toaster Settings: Configure the build environment by running the following:
$ bitbake/lib/toaster/manage.py checksettings
When prompted, paste in the directory paths created
previously during Step 7.
For reference information on Toaster-specific
manage.py
, see the
"Useful Commands"
section.
Install and Set Up the Web Server:
For a production environment, it is recommended that
you install and set up a front-end web server.
This server allows for load balancing and
multi-threading over Toaster and
django
WSGI.
Here is an example that uses Apache web server:
$ apt-get install apache2 libapache2-mod-wsgi $ a2enmod wsgi $ cat /etc/apache2/sites-available/000-default.conf ... # the WSGIPythonPath is global WSGIPythonPath /opt/bitbake/lib/toaster/ ... #snip - in VirtualHost WSGIScriptAlias / /opt/bitbake/lib/toaster/toastermain/wsgi.py <Directory //opt/bitbake/lib/toaster/toastermain/> <Files wsgi.py> Require all granted </Files> </Directory> ...
You need to collect static media from Toaster and continue configuring Apache to serve that static media:
$ mkdir /var/www.html/static && cd /var/www.html/static $ /opt bitbake/lib/toaster/manage.py collectstatic $ cat /etc/apache2/sites-available/000-default.conf ... # in VirtualHost, AHEAD of the WSGIScriptAlias definition Alias /static/ /var/www.html/static/ <Directory /var/www.html/static/> Require all granted </Directory> ... WSGIScript Alias / /opt/bitbake/lib/toaster/toastermain/wsgi.py ...
Start Toaster: Synchronize the databases for Toaster, and then start up the web server. Here is an example that continues with the assumed components from the previous steps:
$ /opt/bitbake/lib/toaster/manage.py syncdb $ /opt/bitbake/lib/toaster/manage.py migrate orm $ /opt/bitbake/lib/toaster/manage.py migrate bldcontrol $ service apache2 restart
For reference information on the
manage.py
commands used here,
see the
"Useful Commands"
section.
Set up Build Control and Open the Web Interface: You need to run the build control manager. You can do this as shown in the following example:
# as the "poky" user, start the runbuilds command in a loop (or put it in crontab!) $ sudo -i -u poky $ while true; do /opt/bitbake/lib/toaster/manage.py runbuilds; sleep 10; done # open up the web interface $ xdg-open http://[server-address]/toastergui/
It is suggested that you enable build control by
setting runbuilds
in the
crontab
as follows:
$ crontab -l * * * * * /opt/bitbake/lit/toaster/manage.py runbuilds
Open the Browser: Once the Apache server is running, connect to it with your favorite browser and verify that the Toaster interface comes up:
http://localhost:8000/toastergui
You can track accesses and errors in the Apache service logs.
The Toaster web interface allows you to do the following:
Browse published layers in the OpenEmbedded Metadata Index that are available for your selected version of the build system.
Import your own layers for building.
Add and remove layers from your configuration.
Set configuration variables.
Select a target or multiple targets to build.
Start your builds.
See what was built (recipes and packages) and what packages were installed into your final image.
Browse the directory structure of your image.
See the value of all variables in your build configuration, and which files set each value.
Examine error, warning and trace messages to aid in debugging.
See information about the BitBake tasks executed and reused during your build, including those that used shared state.
See dependency relationships between recipes, packages and tasks.
See performance information such as build time, task time, CPU usage, and disk I/O.
Following are several videos that show how to use the Toaster GUI:

Table of Contents
In order to configure and use Toaster, you should understand some
concepts and have some basic command reference material available.
This final chapter provides conceptual information on layer sources,
releases, and JSON configuration files.
Also provided is a quick look at some useful
manage.py
commands that are Toaster-specific.
Information on manage.py
commands does exist
across the Web and the information in this manual by no means
attempts to provide a command comprehensive reference.
In general, a "layer source" is a source of information about existing layers. In particular, we are concerned with layers that you can use with the Yocto Project and Toaster. This chapter describes a particular type of layer source called a "layer index."
A layer index is a web application that contains information about a set of custom layers. A good example of an existing layer index is the OpenEmbedded Metadata Index. A public instance of this layer index exists at http://layers.openembedded.org. You can find the code for this layer index's web application at http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/.
When you tie a layer source into Toaster, it can query the layer
source through a
REST
API, store the information about the layers in the Toaster
database, and then show the information to users.
Users are then able to view that information and build layers
from Toaster itself without worrying about cloning or editing
the BitBake layers configuration file
bblayers.conf
.
Tying a layer source into Toaster is convenient when you have many custom layers that need to be built on a regular basis by a community of developers. In fact, Toaster comes pre-configured with the OpenEmbedded Metadata Index.
To use your own layer source, you need to set up the layer source and then tie it into Toaster. This section describes how to tie into a layer index in a manner similar to the way Toaster ties into the OpenEmbedded Metadata Index.
The obvious first step for using a layer index is to have several custom layers that developers build and access using the Yocto Project on a regular basis. This set of layers needs to exist and you need to be familiar with where they reside. You will need that information when you set up the code for the web application that "hooks" into your set of layers.
For general information on layers, see the "BSP Layers" and "Using the Yocto Project's BSP Tools" sections in the Yocto Project Board Support Package (BSP) Developer's Guide.
If you want Toaster to use your layer index, you must host the web application in a server to which Toaster can connect. You also need to give Toaster the information about your layer index. In other words, you have to configure Toaster to use your layer index. This section describes two methods by which you can configure and use your layer index.
In the previous section, the code for the OpenEmbedded Metadata Index (i.e. http://layers.openembedded.org) was referenced. You can use this code, which is at http://git.yoctoproject.org/cgit/cgit.cgi/layerindex-web/, as a base to create your own layer index.
Access the administration interface through a
browser by entering the URL of your Toaster instance and
adding "/admin
" to the end of the
URL.
As an example, if you are running Toaster locally, use
the following URL:
http://127.0.0.1:8000/admin
The administration interface has a "Layer sources" section that includes an "Add layer source" button. Click that button and provide the required information. Make sure you select "layerindex" as the layer source type.
toasterconf.json
File¶
If you do not want to use the Administration
Interface, you can edit the
toasterconf.json
file and reload it to Toaster.
When you set up Toaster in Build Mode, you are prompted to select a Toaster configuration file. This configuration file is used to set up the initial configuration values within the Toaster database including the layer sources. Three versions of the configuration file exist:
The first version of the file is found in the
conf
directory of the
meta-yocto
layer
(i.e.
meta-yocto/conf/toasterconf.json
).
This version contains the default Yocto Project
configuration for Toaster.
You are prompted to select this file during the
Toaster set up process if you had cloned the
poky
repository (i.e.
git://git.yoctoproject.org/poky
).
The second version of the file is in the
conf
directory of the
openembedded-core
layer
(i.e. meta/conf/toasterconf.json
).
This version contains the default OpenEmbedded
configuration for Toaster.
You are prompted to select this file during the
Toaster set up process if you had cloned the
openembedded-core
repository
(i.e.
git://git.openembedded.org/openembedded-core
).
The third version is a sample configuration useful for when you want to set up a hosted service in Build Mode. You can find this version on the File:Toasterconf.json.txt.patch wiki page.
Edit the version of the
toasterconf.json
file you
used to set up your Toaster instance.
In the file, you will find a section for layer sources
such as the following:
"layersources": [ { "name": "Local Yocto Project", "sourcetype": "local", "apiurl": "../../", "branches": ["HEAD", "master", "fido", "dizzy"], "layers": [ { "name": "openembedded-core", "local_path": "meta", "vcs_url": "remote:origin", "dirpath": "meta" }, { "name": "meta-yocto", "local_path": "meta-yocto", "vcs_url": "remote:origin", "dirpath": "meta-yocto" }, { "name": "meta-yocto-bsp", "local_path": "meta-yocto-bsp", "vcs_url": "remote:origin", "dirpath": "meta-yocto-bsp" } ] }, { "name": "OpenEmbedded", "sourcetype": "layerindex", "apiurl": "http://layers.openembedded.org/layerindex/api/", "branches": ["master", "fido", "dizzy"] }, { "name": "Imported layers", "sourcetype": "imported", "apiurl": "", "branches": ["master", "fido", "dizzy", "HEAD"] } ],
You should add your own layer source to this section by following the same format used for the "OpenEmbedded" layer source shown above.
Give your layer source a name, provide the URL of your layer source API, use the source type "layerindex", and indicate which branches from your layer source you want to make available through Toaster. For example, the OpenEmbedded layer source makes available only its "master", "fido", and "dizzy" branches.
The branches must match the branch you set when configuring your releases. For example, if you configure one release in Toaster by setting its branch to "branch-one" and you configure another release in Toaster by setting its branch to "branch-two", the branches in your layer source should be "branch-one" and "branch-two" as well. Doing so creates a connection between the releases and the layer information from your layer source. Thus, when users create a project with a given release, they will see the appropriate layers from your layer source. This connection ensures that only layers that are compatible with the selected project release can be selected for building.
Once you have added this information to the
toasterconf.json
file, save your
changes.
In a terminal window, navigate to the directory that
contains the Toaster database, which by default is the
root of the Yocto Project
Source Directory.
Once you are located in that directory, run the
"loadconf
" command, which takes as
an argument the full path to the
toasterconf.json
file you just edited.
For example, if you cloned the
poky
repository and you edited the
meta-yocto/conf/toasterconf.json
file,
you would type something like the following:
$ bitbake/lib/toaster/manage.py loadconf /home/scottrif/poky/meta-yocto/conf/toasterconf.json
After entering this command, you need to update the
Toaster database with the information coming from your
new layer source.
To do that, you should run the
"lsupdates
" command from the directory
that contains the Toaster database.
Here is an example:
$ bitbake/lib/toaster/manage.py lsupdates
If Toaster can reach the API URL, you should see a message telling you that Toaster is updating the layer source information.
Once the information has been updated, verify the new layer information is available by using the Toaster web interface. To do that, visit the "All compatible layers" page inside a Toaster project. The layers from your layer source should be listed there.
When you create a Toaster project using the web interface, you are asked to choose a "Release." In the context of Toaster, the term "Release" refers to a set of layers and a BitBake version the OpenEmbedded build system uses to build something. As shipped, Toaster is pre-configured with releases that correspond to Yocto Project release branches. However, you can modify, delete, and create new releases according to your needs. This section provides some background information on releases.
As shipped, Toaster is configured to use a specific set of releases. Of course, you can always configure Toaster to use any release. For example, you might want your project to build against a specific commit of any of the "out-of-the-box" releases. Or, you might want your project to build against different revisions of OpenEmbedded and BitBake.
As shipped, Toaster is configured to work with the following releases:
Yocto Project 1.7 "Dizzy" or OpenEmbedded "Dizzy": This release causes your Toaster projects to build against the head of the dizzy branch at http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=dizzy or http://git.openembedded.org/openembedded-core/commit/?h=dizzy.
Yocto Project 1.8 "Fido" or OpenEmbedded "Fido": This release causes your Toaster projects to build against the head of the fido branch at http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=fido or http://git.openembedded.org/openembedded-core/commit/?h=fido.
Yocto Project "Master" or OpenEmbedded "Master": This release causes your Toaster Projects to build against the head of the master branch, which is where active development takes place, at http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/ or http://git.openembedded.org/openembedded-core/log/.
Local Yocto Project or Local OpenEmbedded:
This release causes your Toaster Projects to
build against the head of the poky
or openembedded-core
clone you
have local to the machine running Toaster.
A release consists of the following:
Name:
The name of the release (name
).
This release name never appears in the the Toaster
web interface.
Consequently, a user never sees the release name.
Description:
The textual description of the release
(description
).
This description is what users encounter when creating
projects with the Toaster web interface.
When you configure your release, be sure to use
a description that sufficiently describes and is
understandable.
If Toaster has more than one release configured, the
release descriptions appear listed in a drop down menu
when a user creates a new project.
If Toaster has only one release configured, all
projects created using the web interface take that
release and the drop down menu does not display in the
Toaster web interface.
BitBake:
The Bitbake version (bitbake
)
used to build layers set in the current release.
This version is described by a name, a Git URL, a
branch in the Git URL, and a directory path in the
Git repository.
As an example, consider the following snippet from
a Toaster JSON configuration file.
This BitBake version uses the master branch from the
OpenEmbedded repository:
"bitbake" : [ { "name": "master", "giturl": "git://git.openembedded.org/bitbake", "branch": "master", "dirpath": "" } ]
Here is more detail on each of the items that comprise the BitBake version:
Name:
A string
(name
) used to refer to
the version of BitBake you are using with
Toaster.
This name is never exposed through Toaster.
Git URL:
The URL (giturl
)
for the BitBake Git repository cloned
for Toaster projects.
Branch:
The Git branch, or revision,
(branch
) of the BitBake
repository used with Toaster.
Directory Path:
The sub-directory of the BitBake repository
(dirpath
).
If the Git URL includes more than one
repository, you need to set this directory.
If the URL does not include more than a single
repository, you can set
dirpath
to a null string
(i.e. "").
Branch:
The branch for the layer source
(branch
) used with the release.
For example, for the OpenEmbedded layer source, the
"master", "fido", and "dizzy" branches are available.
Default Layers:
The set of default layers
(defaultlayers
) automatically
added to the project configuration when a project is
created.
Layer Source Priorities
A specification of
layer source
priorities (layersourcepriority
).
In order for Toaster to work as intended, the
"Imported layers" layer source should have the highest
priority, which means that layers manually imported by
users with the "Import layer" functionality will
always be visible and available for selection.
Help Text:
Help text (helptext
) that explains
what the release does when selected.
This help text appears below the release drop-down
menu when you create a Toaster project.
The help text should assist users in making the correct
decision regarding the release to use for a given
project.
To summarize what comprises a release, consider the following
example from a Toaster JSON file.
The configuration names the release "master" and uses the
"master" branch provided by the layer source of type
"layerindex", which is called "OpenEmbedded", and sets
the openembedded-core
layer as the one
to be added by default to any projects created in Toaster.
The BitBake version used would be defined as shown earlier
in the previous list:
"releases": [ { "name": "master", "description": "OpenEmbedded master", "bitbake": "master", "branch": "master", "defaultlayers": [ "openembedded-core" ], "layersourcepriority": { "Imported layers": 99, "Local OpenEmbedded" : 10, "OpenEmbedded" : 0 }, "helptext": "Toaster will run your builds using the OpenEmbedded master branch, where active development takes place. This is not a stable branch, so your builds might not work as expected." } ]
If you are going to be using Toaster in Build Mode, it must be initially configured before use. Configuration customizes layer source settings and Toaster defaults for all users and is performed by the person responsible for Toaster Configuration (i.e the Toaster Administrator). The Toaster Administrator performs this configuration through the Django administration interface.
To make it easier to initially start Toaster, you can import a
pre-defined configuration file using the
loadconf
command.
By convention, the supplied configuration files are named
toasterconf.json
.
The Toaster Administrator can customize the file prior to loading
it into Toaster.
When you set up Toaster locally to run in Build Mode, the system
startup script actively looks for compatible configuration files
and prompts you to select a file to load if it detects that the
database has not been configured.
Three versions of the configuration file exist:
The
meta-yocto/conf/toasterconf.json
in the conf
directory of the
Yocto Project's meta-yocto
layer.
This version contains the default Yocto Project
configuration for Toaster.
You are prompted to select this file during the Toaster
set up process if you cloned the
poky
repository (i.e.
http://git.yoctoproject.org/poky
).
The meta/conf/toasterconf.json
in the conf
directory of the
OpenEmbedded's openembedded-core
layer.
This version contains the default OpenEmbedded
configuration for Toaster.
You are prompted to select this file during the Toaster
set up process if you had cloned the
openembedded-core
repository (i.e.
git://git.openembedded.org/openembedded-core
).
The Toasterconf.json.txt.patch
located on the
File:Toasterconf.json.txt.patch
wiki page.
This version of the file is useful as a sample
configuration for when you want to set up Toaster as a
hosted service in Build Mode.
The toasterconf.json
file consists of
easily readable areas: configuration, layer sources, BitBake,
default release, and releases.
This area of the JSON file sets which variables are exposed to users through the Toaster web interface. Users can easily edit these variables.
The variables you set here are displayed in the
"Configuration variables" page in Toaster.
Minimally, you should set the
MACHINE
variable, which appears to users as part of the project
page in Toaster.
Here is the default config
area:
"config": { "MACHINE" : "qemux86", "DISTRO" : "poky", "IMAGE_FSTYPES": "ext3 jffs2 tar.bz2", "IMAGE_INSTALL_append": "", "PACKAGE_CLASSES": "package_rpm", "SDKMACHINE" : "x86_64" },
This area of the JSON file defines the layer sources Toaster uses. Toaster reads layer information from layer sources. Three types of layer sources exist that Toaster recognizes: Local, LayerIndex, and Imported.
The Local layer source reads layers from Git clones available on your local drive. Using a local layer source enables you to easily test Toaster.
The LayerIndex layer source uses a REST API exposed by instances of the Layer Index application (e.g the public http://layers.openembedded.org/) to read layer data.
The Imported layer source is reserved for layer data manually introduced by the user or Toaster Administrator through the GUI. This layer source lets users import their own layers and build them with Toaster. You should not remove the imported layer source.
Here is the default layersources
area:
"layersources": [ { "name": "Local Yocto Project", "sourcetype": "local", "apiurl": "../../", "branches": ["HEAD", "master", "fido", "dizzy"], "layers": [ { "name": "openembedded-core", "local_path": "meta", "vcs_url": "remote:origin", "dirpath": "meta" }, { "name": "meta-yocto", "local_path": "meta-yocto", "vcs_url": "remote:origin", "dirpath": "meta-yocto" }, { "name": "meta-yocto-bsp", "local_path": "meta-yocto-bsp", "vcs_url": "remote:origin", "dirpath": "meta-yocto-bsp" } ] }, { "name": "OpenEmbedded", "sourcetype": "layerindex", "apiurl": "http://layers.openembedded.org/layerindex/api/", "branches": ["master", "fido", "dizzy"] }, { "name": "Imported layers", "sourcetype": "imported", "apiurl": "", "branches": ["master", "fido", "dizzy", "HEAD"] } ],
This area of the JSON file defines the version of BitBake Toaster uses. As shipped, Toaster is configured to recognize four versions of BitBake: master, fido, dizzy, and HEAD.
Here is the default bitbake
area:
"bitbake" : [ { "name": "master", "giturl": "remote:origin", "branch": "master", "dirpath": "bitbake" }, { "name": "fido", "giturl": "remote:origin", "branch": "fido", "dirpath": "bitbake" }, { "name": "dizzy", "giturl": "remote:origin", "branch": "dizzy", "dirpath": "bitbake" }, { "name": "HEAD", "giturl": "remote:origin", "branch": "HEAD", "dirpath": "bitbake" } ],
This area of the JSON file establishes a default release used by Toaster. As shipped, Toaster uses the "master" release.
Here is the statement in the JSON file that establishes the default release:
"defaultrelease": "master",
This area of the JSON file defines the versions of the OpenEmbedded build system Toaster recognizes. As shipped, Toaster is configured to work with the four releases described in the "Pre-Configured Releases" section.
Here is the default releases
area:
"releases": [ { "name": "master", "description": "Yocto Project master", "bitbake": "master", "branch": "master", "defaultlayers": [ "openembedded-core", "meta-yocto", "meta-yocto-bsp"], "layersourcepriority": { "Imported layers": 99, "Local Yocto Project" : 10, "OpenEmbedded" : 0 }, "helptext": "Toaster will run your builds using the tip of the <a href=\"http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/\">Yocto Project master branch</a>, where active development takes place. This is not a stable branch, so your builds might not work as expected." }, { "name": "fido", "description": "Yocto Project 1.8 Fido", "bitbake": "fido", "branch": "fido", "defaultlayers": [ "openembedded-core", "meta-yocto", "meta-yocto-bsp"], "layersourcepriority": { "Imported layers": 99, "Local Yocto Project" : 10, "OpenEmbedded" : 0 }, "helptext": "Toaster will run your builds with the tip of the <a href=\"http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=fido\">Yocto Project 1.8 \"Fido\"</a> branch." }, { "name": "dizzy", "description": "Yocto Project 1.7 Dizzy", "bitbake": "dizzy", "branch": "dizzy", "defaultlayers": [ "openembedded-core", "meta-yocto", "meta-yocto-bsp"], "layersourcepriority": { "Imported layers": 99, "Local Yocto Project" : 10, "OpenEmbedded" : 0 }, "helptext": "Toaster will run your builds with the tip of the <a href=\"http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=dizzy\">Yocto Project 1.7 \"Dizzy\"</a> branch." }, { "name": "local", "description": "Local Yocto Project", "bitbake": "HEAD", "branch": "HEAD", "defaultlayers": [ "openembedded-core", "meta-yocto", "meta-yocto-bsp"], "layersourcepriority": { "Imported layers": 99, "Local Yocto Project" : 10, "OpenEmbedded" : 0 }, "helptext": "Toaster will run your builds with the version of the Yocto Project you have cloned or downloaded to your computer." } ]
In addition to the web user interface and the scripts that start
and stop Toaster, command-line commands exist through the
manage.py
management script.
You can find general documentation on
manage.py
at the
Django
site.
However, several manage.py
commands have been
created that are specific to Toaster and are used to control
configuration and back-end tasks.
You can locate these commands in the
Source Directory
(e.g. poky
) at
bitbake/lib/manage.py
.
This section documents those commands.
When using manage.py
commands given
a default configuration, you must be sure that your
working directory is set to the
Build Directory.
Using manage.py
commands from the
Build Directory allows Toaster to find the
toaster.sqlite
file, which is located
in the Build Directory.
For non-default database configurations, it is possible
that you can use manage.py
commands
from a directory other than the Build directory.
To do so, the
toastermain/settings.py
file must be
configured to point to the correct database backend.
buildslist
¶
The buildslist
command lists all builds
that Toaster has recorded.
Access the command as follows:
$ bitbake/lib/toaster/manage.py buildslist
The command returns a list, which includes numeric identifications, of the builds that Toaster has recorded in the current database.
You need to run the buildslist
command
first to identify existing builds in the database before
using the
builddelete
command.
Here is an example that assumes default repository and build
directory names:
$ cd ~/poky/build $ python ../bitbake/lib/toaster/manage.py buildslist
If your Toaster database had only one build, the above
buildslist
command would return something
like the following:
1: qemux86 poky core-image-minimal
builddelete
¶
The builddelete
command deletes data
associated with a build.
Access the command as follows:
$ bitbake/lib/toaster/manage.py builddelete build_id
The command deletes all the build data for the specified
build_id
.
This command is useful for removing old and unused data from
the database.
Prior to running the builddelete
command, you need to get the ID associated with builds
by using the
buildslist
command.
perf
¶
The perf
command measures Toaster
performance.
Access the command as follows:
$ bitbake/lib/toaster/manage.py perf
The command is a sanity check that returns page loading times in order to identify performance problems.
checksettings
¶
The checksettings
command verifies
existing Toaster settings.
Access the command as follows:
$ bitbake/lib/toaster/manage.py checksettings
In Build Mode, Toaster uses settings that are based on the
database to configure the building tasks.
The checksettings
command verifies that
the database settings are valid in the sense that they have
the minimal information needed to start a build.
In order for the checksettings
command
to work, the database must be correctly set up and not have
existing data.
To be sure the database is ready, you can run the following:
$ bitbake/lib/toaster/manage.py syncdb $ bitbake/lib/toaster/manage.py migrate orm $ bitbake/lib/toaster/manage.py migrate bldcontrol
After running these commands, you can run the
checksettings
command.
loadconf
¶
The loadconf
command loads an
existing Toaster configuration file (JSON file).
You must run this on a new database that does not have any
data.
Running this command on an existing database that has data
results in errors.
Access the command as follows:
$ bitbake/lib/toaster/manage.py loadconf filepath
The loadconf
command configures a database
based on the supplied existing
toasterconf.json
file.
For information on the toasterconf.json
,
see the
"JSON Files"
section.
runbuilds
¶
The runbuilds
command launches
scheduled builds.
Access the command as follows:
$ bitbake/lib/toaster/manage.py runbuilds
The runbuilds
command checks if
scheduled builds exist in the database and then launches them
per schedule.
The command returns after the builds start but before they
complete.
The Toaster Logging Interface records and updates the database
when the builds complete.
