Custom Image Registry

[geoff-carr-bzy]

How can the default pause container image used for the portworx-api and portworx-kvdb pods be overridden? I have specified a custom image registry in the install spec which works for just about everything else but for the pause container it appends the original registry and image path as follows: -

Back-off pulling image "docker.repo/k8s.gcr.io/pause:3.1"

I need it to be: -

docker.repo/pause:3.1

I have tried to edit and update the portworx-api DaemonSet but it then reverts back to the original so I am guess the operator is resetting it.

Found this which suggests adding // to the custom registry path which fixes the pause container pull but then breaks everything else: -

#319

Same issue for the stork-scheduler pods: -

Back-off pulling image "docker.repo/gcr.io/google_containers/kube-scheduler-amd64:v1.18.6"

however the stork pods work: -

Also having this issue, we're looking to migrate from the Pure Storage Orchestrator CSI driver and this is blocking us from deploying this operator, @piyush-nimbalkar apologies for the ping, this issue has been open for a while.

Sorry guys for the late response. This just slipped my radar.
Due to an old bug which was not considering gcr.io and k8s.gcr.io as image repositories, we had this misconstructed path. To avoid breaking existing deployments, we came up with an annotation to fix these repositories.

You can add operator.libopenstorage.org/common-image-registries: "gcr.io,k8s.gcr.io" annotation to the StorageCluster object. The operator will then consider them as normal registries like docker.io or quay.io and should construct the correct path for the above images that are causing issues.

apiVersion: core.libopenstorage.org/v1
kind: StorageCluster
metadata:
  name: px-cluster
  namespace: kube-system
  annotations:
    operator.libopenstorage.org/common-image-registries: "gcr.io,k8s.gcr.io"
spec:
  ...
