Cohesity Cloud Scale Technology Manual Deployment Guide for Kubernetes Clusters

Resolve an issue related to pulling an image from the container registry

Primary or media server failed to deploy with ImagePullBackOff error. If the pod Status field displays ImagePullBackOff, it means that the pod could not start because Kubernetes cannot pull a container image. A misspelled registry or image name or image registry being not reachable can cause a ImagePullBackOff status.

Run the $ k get all -n netbackup-operator-system command.

The output should look like:

            NAME            READY   STATUS             RESTARTS   AGE
pod/msdp-operator
-controller-manager-
65d8fd7c4d-bsgms            2/2     Running            0          7m9s

pod/netbackup-operator
-controller-manager-
5df6f58b9b-6ftt9            1/2     ImagePullBackOff   0          13s

For additional details, use the following command:

$ kubectl describe pod/<pod_name> -n netbackup-operator-system

Resolve this issue using any of the following methods:

  • Check if image name and tag are correct. If not, edit and update the environment CR using the helm upgrade cloudscale cloudscale-<version>.tgz -n netbackup --reuse-values --set environment.primary.tag=<tag> command with correct image name and tag, and then save the changes.

  • Check if the user is authorized and has permissions to access the Azure/AWS container registry.
