Confirm that the images are accessible to the cluster by doing one of the following:
- Allowing access to the internet sources (DockerHub).
- Providing and configuring container images for an internal registry.
If using in-cluster builds, confirm that a container image registry with write access has been configured within your cluster.
Confirm that the registry/ies are configured in the cluster, Service Account, and/or Onload CR as required, such as being insecure, internally-signed, or with a pull secret. In OpenShift®, this is configured in image.config.openshift.io/cluster CR.
Check whether the images are stale. This is particularly of concern if images are cached locally using tags that do not completely uniquely identify the image, including any particular build parameters if they are built in-house. Related to this is the imagePullPolicy in Onload CR.
