Verified steps

  1. Install the Flux image-reflector-controller and image-automation-controller components (included in `flux bootstrap` with `--components-extra=image-reflector-controller,image-automation-controller`)
  2. Create an ImageRepository resource pointing to your container registry; annotate it with credentials via a Secret if the registry is private
  3. Create an ImagePolicy referencing the ImageRepository; define a `filterTags` policy (e.g., semver `>=1.0.0`) to select which tag to track
  4. Mark the image reference in your Kubernetes manifest with a Flux marker comment so the automation controller knows which field to update
  5. Create an ImageUpdateAutomation resource pointing to your Git repository and source branch; configure it to commit on detected image changes
  6. Verify with `flux get image policy <name>` that the latest tag is resolved, then check Git for an automated commit updating the image tag
