How are subscription details passed from RHEL host to ubi container ?

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux 7
  • Red Hat Enterprise Linux 8
  • Red Hat Enterprise Linux 9
  • podman
  • docker

Resolution

  • Red Hat entitlements are passed from a subscribed Red Hat host as a secrets mount (defined in /usr/share/containers/mounts.conf) on the host running podman/the container engine:
$ cat /usr/share/containers/mounts.conf
/usr/share/rhel/secrets:/run/secrets

  • yum, dnf, and microdnf commands know to look for entitlement data at this path. If it's not present, then they cannot use Red Hat entitled content such as the RHV repositories because they lack the keys/content access the host has.

  • Please note that this is applicable only for Red Hat shipped/provided docker and podman on a RHEL host. If podman/docker not shipped by Red Hat is used, then some additional steps are required to be performed to pass the subscription data to non Red Hat provided docker/podman.
