migrate to FBC for manage operator metadata

[sunya-ch]

Background

To make multi-nic-cni operator available on OpenShift operator hub, we need to make a PR to the repo https://github.com/redhat-openshift-ecosystem/community-operators-prod.

Operator hub basically provides RedHat catalog source which is operated OLM.

Catalog is an image that contains an arranged collection of bundle and bundle is an image that contains a collection of deployment yaml files. Operator SDK provides an API to generate the bundle and the catalog.

This document gives an explanation about operator versioning and how to write the ci.yaml. We are now using the default mode (replace).

Note (current detailed operation):

I have forked this repo under my private account and basically update on the multi-nic-cni-1.2 branch: https://github.com/sunya-ch/ocp-community-operators/tree/multi-nic-cni-1.2 and make a PR from there and here is the most recently PR that I pushed and it was merged. I have a script to move to my local multi-nic-cni project, checkout a branch with inputted version, run make bundle and copy necessary file to the subfolder.

Issue

Refer to the warning from operator hub integration: redhat-openshift-ecosystem/community-operators-prod#5598 (comment)

redhat-openshift-ecosystem/community-operators-prod#5031 (comment) is a new way to manage operator metadata. This operator does not use FBC. Consider migrating for better maintainability.

Action items

Follow the step in https://redhat-openshift-ecosystem.github.io/operator-pipelines/users/fbc_workflow/.

• Generate catalogs using templates
  • load updated files (run wget command as instructed in the website)
  • create catalog template refer to steps in https://redhat-openshift-ecosystem.github.io/operator-pipelines/users/fbc_onboarding/ (for now, we can keep the same structure of the release in https://foundation-model-stack.github.io/multi-nic-cni/release/)
• Updating existing catalogs
• Test building catalog (run make catalog) and try deploying it via catalog-source.yaml (not via operator hub)
