Learn how to update your buildpack-packager and machete CF buildpack test framework, which are used for CF system buildpack development.
The buildpack-packager
packages buildpacks and machete
provides an integration test framework.
The CF Buildpacks team uses the gems-and-extensions pipeline to:
buildpack-packager
and machete
.The following steps assume you are using a Concourse deployment of the buildpacks-ci
pipelines.
At the end of the process, there is a new GitHub release. Updates are then applied to the buildpacks.
To update the version of either gem in a buildpack:
<gemname>-specs
for the gem was updated successfully and ran on the commit you plan to update.Start the <gemname>-tag
job to update (“bump”) the version of the gem.
The <gemname>-release
job starts and creates a new GitHub release of the gem.
Each of the buildpack pipelines, for example, the go-buildpack pipeline has a job that watches for new releases of the gem. When a new release is detected, the buildpack’s cf.Gemfile
is updated to that release version.
cf.Gemfile
starts the full integration test suite for that buildpack.The final step starts all buildpack test suites simultaneously, and causes contention for available shared BOSH lite test environments.
