The error comes from using the plan name to build a name for a mount point in the container, which has stricter rules for labels than the migplan name itself. Since this mount point is an EmptyDir volume source that's not shared outside the container, the solution is probably just to remove the migplan name from the mount and just call it "volume-1". We'll need to verify that this doesn't break anything, though, and make sure there aren't other errors related to other places where the migplan name is used. Fix is here: https://github.com/fusor/mig-controller/pull/362 Verified in CAM 1.1.0 version from osbs image: image-registry.openshift-image-registry.svc:5000/rhcam-1-1/openshift-migration-controller-rhel8@sha256:b55c0c36333656a46e1d0500cf11cc8aa06e093d312e7c54f8e1075d4ab4c6c1 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: Creating a migplan with a dot in the name (or anything other than lowercase alphanumeric characters plus "-") results in a reconcile error Version-Release number of selected component (if applicable): CAM 1.0 How reproducible: Always Steps to Reproduce: 1. Create a migplan with a dot in the name (i.e. "migplan-1.1") 2. Wait for reconcile. 3. Look at migplan yaml output Actual results: Reconcile error is displayed: message: 'Reconcile failed: [DeploymentConfig.apps.openshift.io "registry-registry-example-plan-4.2-khf6n" is invalid: [spec.template.spec.volumes[0].name: Invalid value: "registry-registry-example-plan-4.2-khf6n-volume-1": a DNS-1123 label must consist of lower case alphanumeric characters or ''-'', and must start and end with an alphanumeric character (e.g. ''my-name'', or ''123-abc'', regex used for validation is ''[a-z0-9]([-a-z0-9]*[a-z0-9])?''), spec.template.spec.containers[0].name: Invalid value: "registry-registry-example-plan-4.2-khf6n": a DNS-1123 label must consist of lower case alphanumeric characters or ''-'', and must start and end with an alphanumeric character (e.g. ''my-name'', or ''123-abc'', regex used for validation is ''[a-z0-9]([-a-z0-9]*[a-z0-9])?''), spec.template.spec.containers[0].volumeMounts[0].name: Not found: "registry-registry-example-plan-4.2-khf6n-volume-1"]].
