Migrating to the unified private EDB container registry v1.27.1

What's changing

Previously, EDB published operator and operand images selectively to one of several private repositories: k8s_standard, k8s_enterprise, k8s_standard_pgd, and k8s_enterprise_pgd. Your repository was determined by your subscription level and the operators you wanted to use. Also, public registries may have been used for some operand images. In particular, EDB provided numerous images via public repositories hosted on quay.io.

Now, the EDB Postgres® AI for CloudNativePG™ Cluster and EDB Postgres Distributed for Kubernetes operators and associated operands are provided in a single repository, k8s. If your subscription includes access to a given image, you can pull it from this repository. The old repositories remain available for now, but new images are published to the unified repository. Thus, future operator and operand upgrades will require migrating to the unified repository.

Summary of changes

Scope of changes

• Pull secrets. Because the old system relied on specifying the desired repository by username when authenticating, update the credentials stored in secrets that Kubernetes uses to pull images.
• Helm values. If you're using Helm charts, update the image.repository and image.imageCredentials.username values.
• Manifest image names. If you're using custom manifests that specify one of the old repository paths as part of an imageName or images[].image value, update those as well.

Migration processes

Updating credentials

In all cases, begin by updating any stored credentials used by your system.

Collect the following information:

• Your EDB account token
• The name of the repository: k8s
• The repository server: docker.enterprisedb.com

The instructions that follow assume your token is in an environment variable named EDB_SUBSCRIPTION_TOKEN.

Pull secrets

If you're working directly with operator manifests, update pull secrets in the relevant namespaces.

For EDB Postgres® AI for CloudNativePG™ Cluster, the default namespace is postgresql-operator-system. To create or update the pull secret in this namespace, run:

kubectl create secret -n postgresql-operator-system docker-registry edb-pull-secret \
  --docker-server=docker.enterprisedb.com \
  --docker-username=k8s \
  --docker-password=${EDB_SUBSCRIPTION_TOKEN} \
  --dry-run=client -o=json \
  | kubectl apply -f -

For EDB Postgres Distributed for Kubernetes, the default namespace is pgd-operator-system. To create or update the pull secret in this namespace, you would run:

kubectl create secret -n pgd-operator-system docker-registry edb-pull-secret \
  --docker-server=docker.enterprisedb.com \
  --docker-username=k8s \
  --docker-password=${EDB_SUBSCRIPTION_TOKEN} \
  --dry-run=client -o=json \
  | kubectl apply -f -

OpenShift pull secrets

The relevant pull secrets live in the openshift-operators namespace on OpenShift.

For EDB Postgres® AI for CloudNativePG™ Cluster and operand images, you'll need to update postgresql-operator-pull-secret:

oc create secret -n openshift-operators docker-registry postgresql-operator-pull-secret \
  --docker-server=docker.enterprisedb.com \
  --docker-username=k8s \
  --docker-password=${EDB_SUBSCRIPTION_TOKEN} \
  --dry-run=client -o=json \
  | oc apply -f -

If you're using the EDB Postgres Distributed for Kubernetes operator, you'll also need to update pgd-operator-pull-secret:

oc create secret -n openshift-operators docker-registry pgd-operator-pull-secret \
  --docker-server=docker.enterprisedb.com \
  --docker-username=k8s \
  --docker-password=${EDB_SUBSCRIPTION_TOKEN} \
  --dry-run=client -o=json \
  | oc apply -f -

Updating Helm values

For your EDB Postgres® AI for CloudNativePG™ Cluster Helm releases, you'll need to update override values for both image.repository and image.imageCredentials.username:

helm upgrade --reuse-values \
  --set image.repository=docker.enterprisedb.com/k8s/edb-postgres-for-kubernetes \
  --set image.imageCredentials.username=k8s \
  edb-pg4k \
  edb/edb-postgres-for-kubernetes

(here, edb-pg4k and edb/edb-postgres-for-kubernetes are the release and pathname used in other examples; substitute your own values)

For your EDB Postgres Distributed for Kubernetes Helm releases, you'll need to override values for both global.image.repository and image.imageCredentials.username:

helm upgrade --reuse-values \
  --set global.image.repository=docker.enterprisedb.com/k8s \
  --set image.imageCredentials.username=k8s \
  edb-pg4k-pgd \
  edb/edb-postgres-distributed-for-kubernetes

(here, edb-pg4k-pgd and edb/edb-postgres-distributed-for-kubernetes are the release and pathname used in other examples; substitute your own values)

Updating image paths in manifests

For operators or operands deployed via custom manifests (including the examples contained within current and past versions of this documentation), you'll need to update these manifests directly to update image references that specify the server and repository name as part of the image name.

Refer to the repository paths under Summary of changes for a full list of paths that you'll need to update if found among your manifests.

Example: imageName

apiVersion: postgresql.k8s.enterprisedb.io/v1
kind: Cluster
metadata:
  name: postgresql-extended-cluster
spec:
  instances: 3
  imageName: docker.enterprisedb.com/k8s_enterprise/edb-postgres-extended:17-standard-ubi9

Here is a cluster manifest that deploys three EDB Postgres Extended instances. The image path referenced in spec.imageName is out of date and will need to be updated:

  imageName: docker.enterprisedb.com/k8s/edb-postgres-extended:17-standard-ubi9

Deploy this update in the usual manner (kubectl apply ...).

Example: ImageCatalog images

Consider this (old, outdated) sample ImageCatalog manifest:

apiVersion: postgresql.k8s.enterprisedb.io/v1
kind: ImageCatalog
metadata:
  name: postgresql
  namespace: default
spec:
  images:
    - major: 13
      image: quay.io/enterprisedb/postgresql:13.21
    - major: 14
      image: quay.io/enterprisedb/postgresql:14.18
    - major: 15
      image: quay.io/enterprisedb/postgresql:15.13
    - major: 16
      image: quay.io/enterprisedb/postgresql:16.9
    - major: 17
      image: quay.io/enterprisedb/postgresql:17.5

Here is an ImageCatalog manifest that defines a set of images to be referenced elsewhere. The image paths referenced in `spec.images[].image` values are out of date and will need to be updated:

```yaml
apiVersion: postgresql.k8s.enterprisedb.io/v1
kind: ImageCatalog
metadata:
  name: postgresql
  namespace: default
spec:
  images:
    - major: 15
      image: docker.enterprisedb.com/k8s/postgresql:15.14-standard-ubi9
    - major: 16
      image: docker.enterprisedb.com/k8s/postgresql:16.10-standard-ubi9
    - major: 17
      image: docker.enterprisedb.com/k8s/postgresql:17.6-standard-ubi9
    - major: 18
      image: docker.enterprisedb.com/k8s/postgresql:18.0-standard-ubi9

Deploy this update in the usual manner (kubectl apply ...).
