In some deployment environments (gating, integration, some Wind River lab environments), the DCAE policy handler fails to deploy, with an error message like this:

Error: failed to start container "dcae-policy-handler": Error response from daemon: OCI runtime create failed: invalid mount {Destination:logs Type:bind Source:/var/lib/docker/volumes/d1bb2804db44ede9164f109b7a9c147bc25421a03b1ccf794506f255e5e308e4/_data Options:[rbind]}: mount destination logs not absolute: unknown

The container runtime system is trying to create this mount because the image has a mount definition in it, created by a VOLUME statement in the Dockerfile:

VOLUME logs

In earlier deployment environments, this doesn't appear to cause a problem, but recently we have seen the above error in some newer environments.

The volume doesn't appear to be necessary (the Helm chart for policy handler mounts an emptyDir volume at /app/logs).
