Question

Your team stores base manifests in a directory with a kustomization.yaml referencing deployment.yaml and service.yaml. You need to create a production overlay that deploys everything into the 'prod' namespace and bumps the container image tag from 'v1.2.0' to 'v1.3.0' without editing the base files. Which overlay kustomization.yaml configuration accomplishes this most idiomatically with Kustomize?

Accepted Answer

In the overlay, set 'resources: [../base]', 'namespace: prod', and add an 'images:' entry with 'name: myapp' and 'newTag: v1.3.0'.

Answer

In the overlay, set 'bases: [../base]' and copy deployment.yaml into the overlay with the namespace field and new image tag hardcoded.

Answer

Run 'kubectl apply -k ../base --namespace prod' and then 'kubectl set image' after the base is applied to update the tag.

Answer

In the overlay, add 'patchesStrategicMerge:' pointing to the base deployment.yaml with the namespace and image changed inline.
