Update the container image tag of the Online Boutique apps

By default, the Online Boutique apps are targeting the latest release version (see the list of versions here). You may need to change this image tag to target a specific version, this Kustomize variation will help you setting this up.

Change the default container image tag via Kustomize

To automate the deployment of the Online Boutique apps with a specific container imag tag, you can leverage the following variation with Kustomize.

From the kustomize/ folder at the root level of this repository, execute this command:

TAG=v1.0.0
sed -i "s/CONTAINER_IMAGES_TAG/$TAG/g" components/container-images-tag/kustomization.yaml
kustomize edit add component components/container-images-tag

Note: this Kustomize component will update the container image tag of the image: field in all Deployments.

This will update the kustomize/kustomization.yaml file which could be similar to:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- base
components:
- components/container-images-tag

You can locally render these manifests by running kubectl kustomize . as well as deploying them by running kubectl apply -k ..

Important notes: if combining with the other variations, here are some considerations:

• should be placed before components/container-images-registry

So for example here is the order respected:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
- base
components:
- components/container-images-tag
- components/container-images-registry
