Without this patch the control repository does not contain any scripts
to execute CI jobs for Puppet code deployment. This patch addresses the
problem by adding a Gitlab CI job configuration with three jobs defined
across two stages. The test stage executes first with a Syntax and a
Lint job executing in parallel. If an environment branch has been
pushed, one matching `developemnt`, `testing`, `production` or starting
with the prefix `playground`, the deploy stage is executed.
The deploy stage requires a Gitlab secret environment variable,
PUPPET_TOKEN. This environment variable is the puppet access token
configured with Code Manager.
The test stage runs the following syntax checks:
* yaml files (*.yml, *.yaml)
* json files (*.json)
* bash scripts (*.sh)
* ruby scripts (*.rb)
* puppet manifests (*.pp)
* erb files (*.erb)
The behavior of the checks are to check only files modified relative to
a base branch, defaulting to `production`. This avoids running syntax
checks against files which have not been modified by the merge request.
The check uses `git diff --name-status` to identify changed files across
multiple commits in a topic branch.
The lint checks rely on bundler and the Gemfile to install numerous lint
checks.
Gem libraries are installed in a per-job location in $HOME. This is an
intentional compromise between installing into a system GEM_PATH
element, which would create library conflicts with other jobs, and the
job workspace, which would cause gem libraries to be installed from the
network on each job invocation.
