+# Update the container registry of the Online Boutique apps
+
+By default, Online Boutique's services' container images are pulled from a public container registry (`gcr.io/google-samples/microservices-demo`). One best practice is to have these container images in your own private container registry. The Kustomize variation in this folder can help with using your own private container registry.
+
+## Change the default container registry via Kustomize
+
+To automate the deployment of Online Boutique integrated with your own container registry, you can leverage the following variation with [Kustomize](../..).
+
+From the `kustomize/` folder at the root level of this repository, execute this command:
+```bash
+REGISTRY=my-registry # Example: gcr.io/my-project/my-directory
+sed -i "s|CONTAINER_IMAGES_REGISTRY|${REGISTRY}|g" components/container-images-registry/kustomization.yaml
+kustomize edit add component components/container-images-registry
+```
+_Note: this Kustomize component will update the container registry in the `image:` field in all `Deployments`._
+
+This will update the `kustomize/kustomization.yaml` file which could be similar to:
+```yaml
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+- base
+components:
+- components/container-images-registry
+```
+
+You can (optionally) locally render these manifests by running `kubectl kustomize .`.
+You can deploy them by running `kubectl apply -k .`.

+# Add a suffix to the image tag of the Online Boutique container images
+
+You may want to add a suffix to the Online Boutique container image tag to target a specific version.
+The Kustomize Component inside this folder can help.
+
+## Add a suffix to the container image tag via Kustomize
+
+To automate the deployment of the Online Boutique apps with a suffix added to the 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:
+```bash
+SUFFIX=-my-suffix
+sed -i "s/CONTAINER_IMAGES_TAG_SUFFIX/$SUFFIX/g" components/container-images-tag-suffix/kustomization.yaml
+kustomize edit add component components/container-images-tag-suffix
+```
+_Note: this Kustomize component will add a suffix to the container image tag of the `image:` field in all `Deployments`._
+
+This will update the `kustomize/kustomization.yaml` file which could be similar to:
+```yaml
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+- base
+components:
+- components/container-images-tag-suffix
+```
+
+You can locally render these manifests by running `kubectl kustomize . | sed "s/$SUFFIX$SUFFIX/$SUFFIX/g"` as well as deploying them by running `kubectl kustomize . | sed "s/$SUFFIX$SUFFIX/$SUFFIX/g" | kubectl apply -f`.
+
+_Note: for this variation, `kubectl apply -k .` alone won't work because there is a [known issue currently in Kustomize](https://github.com/kubernetes-sigs/kustomize/issues/4814) where the `tagSuffix` is duplicated. The `sed "s/$SUFFIX$SUFFIX/$SUFFIX/g"` commands above are a temporary workaround._
+
+## Combine with other Kustomize Components
+If you're combining this Kustomize Component with other variations, here are some considerations:
+- `components/container-images-tag-suffix` should be placed before `components/container-images-registry`
+- `components/container-images-tag-suffix` should be placed after `components/container-images-tag`
+
+So for example here is the order respected:

+resources:
+- base
+components:
+- components/container-images-tag
