Toaster is a web interface to the Yocto Project's
|
|
<ulink url='&YOCTO_DOCS_REF_URL;#build-system-term'>OpenEmbedded build system</ulink>.
|
|
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.

Toaster allows you to configure and run builds, and it

<emphasis>Configure and Run Builds:</emphasis>
|
|
You can use the Toaster web interface to configure and
|
|
start your builds.
|
|
Builds started using the Toaster web interface are
|
|
organized into projects.
|
|
When you create a project, you are asked to select a
|
|
release, or version of the build system you want to
|
|
use for the project builds.
|
|
As shipped, Toaster supports Yocto Project releases 1.8
|
|
and beyond.
|
|
With the Toaster web interface, you can:
|
|

Browse layers listed in the various

OpenEmbedded Metadata Index at

Toaster also allows you to configure and run your builds
|
|
from the command line, and switch between the command line and
|
|
the web interface at any time.
|
|
Builds started from the command line appear within a special
|
|
Toaster project called "Command line builds".

<emphasis>Information About the Build Process:</emphasis>
|

Toaster also records extensive information about your builds.
|
|
Toaster collects data for builds you start from the web
|
|
interface and from the command line as long as Toaster
|
|
is running.
|
|
<note>
|
|
You must start Toaster before the build or it will not

collect build data.

You can set Toaster up to run as a local instance or as a shared
|
|
hosted service.
|

</para>
|
|
|
|
<para>
|
|
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:
