Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Checked yesterday - source: GitHub (zarguell/ubi8)

Resources & Compatibility

ARM (e.g. Raspberry Pi) is supported.

Checked 14 days ago - source: Docker Hub image tags and published docs

First-install notes

  • Usage UBI8 is a base layer, not a ready-to-run application. Pull the image and build your software on top of it, for example by starting a Dockerfile with FROM redhat/ubi8 and adding your application layers over it. source
  • Using UBI 8 as a base image UBI 8 is a base image, not an app to run directly. Pull redhat/ubi8 from Docker Hub and set it as the FROM layer in your Dockerfiles; Red Hat publishes security updates for the image. source

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.
