List all containers images used for each deployment bootstrap, management, workload
Summary
Create an exhaustive list of all containers images used in a cluster deployment.
"All images" means:
- active pods images once cluster is deployed
- but also dead pods, jobs, initcontainers...
This list should be created for:
- bootstrap cluster
- management cluster
- workload cluster
Details
This list will help us to audit our deployments, and control which images versions are really needed.
Those lists should be saved as YAML files and could be saved in CI pipeline as artifacts for future use.
