Issue

Docker or Podman, as provided by Red Hat on Red Hat Enterprise Linux 7 or 8, automatically mounts host subscription data into containers as a secret via the /run/secrets directory.
Docker as provided by other vendors, or any Docker package not provided by Red Hat, may not provide methods for automatically attaching subscription data.
What manual steps can be taken to automatically attach host entitlement data directly into containers running non-Red Hat container solutions?

Non-Red Hat container solution such as Docker-CE or Docker-EE
Non-Red Hat Kubernetes solutions
Red Hat Enterprise Linux 7
Red Hat Enterprise Linux 8
Red Hat provided base images such as registry.redhat.io/rhel7 or registry.redhat.io/ubi8
