When using ImageStream name in DeploymentConfig the pod's image gets resolved to docker.io instead of internal registry

Solution Verified - Updated -

Issue

  • When using ImageStream name in DeploymentConfig as image value, the actual image in the Pod gets resolved to docker.io instead of internal registry.

  • Getting this message in the OpenShift events output:

Raw
Failed to pull image "example": rpc error: code = Unknown desc = Error reading manifest in docker.io/example/example: errors: denied: requested access to the resource is denied unauthorized: authentication required
  • Cannot pull images after update from 4.6.44 to 4.6.46
  • The image stream names are no longer resolved into image references in pods that are created by deployment configs, in some cases in statefulsets, and possibly in other objects.

Environment

  • Red Hat OpenShift Container Platform
    • 4.6.45+
    • 4.7.28+
