Preflight Controller

This is a very-alpha controller that runs Openshift Preflight as a job in a Kubernetes Cluster on creation of a PreflightCheck resource.

Quick Run

Assuming KUBECONFIG is set, and a running cluster with admin privs (because the controller runs on your machine)

# Clone the repo
git clone https://github.com/opdev/preflight-controller && cd preflight-controller

# Install the CRD
make install && make run

# Apply the samples (or configure your own)
make install-samples

# Watch the samples do their thing (they don't all succeed)
watch oc get preflightcheck
# sample output is below

# When done, clean up the samples.
make uninstall-samples

Sample output of watch command:

$ oc get preflightcheck

Notes on behavior

• This spins up a single job for a given PreflightCheck. If an job already exists for an instance, no other jobs are created.
• This will attempt the job a single time.
• The type of Preflight checks to apply depend on which PreflightCheck.Spec.CheckOptions exist in your manifest.
• Credentials aren't fully wired up, so they will not function as expected as of the time of this writing.
