## Common questions

### Do I need to manage Red Hat subscriptions on the build host to get repository access while building UBI8 images?

If you subscribe the build host with subscription-manager, the RHEL repository RPMs covered by your subscription become available during the build. If using podman natively, the host subscription context may need to be passed into the build.

### Why might UBI8 images fail to update packages to UBI8.4?

A Red Hat solution documents that as of 2021-05-21 UBI8 images were unable to update packages to UBI8.4 or install new packages. The solution is marked verified and was later updated.

### What AppStream naming change can affect ubi8/ubi-minimal Docker images?

The AppStream repository name changed in ubi8/ubi-minimal, so images using the old ubi-8-appstream name can fail. The docs were updated to mention the new names.

### Can I inspect public vulnerability data for UBI containers?

A Red Hat UBI discussion notes a public container health index that can show potential published vulnerabilities in UBI containers.
