WalkthroughThe Dockerfiles now configure ChangesPQC container enablement
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The PR updates four runtime images but currently prevents expected base-image security updates and leaves the containers running as root. These security configuration issues affect every downstream and MCE runtime image, so the PR is not ready to merge until they are addressed.

Security Misconfiguration (CWE-16)
Reachability: Internal · Exploitability: Difficult
Remove digest pinning from Red Hat UBI PQC image references. The digest overrides the :latest tag, preventing Red Hat's automatic security updates on floating tags. Red Hat images must use floating tags per the coding guideline.
Update all four Dockerfiles to remove the @sha256:... digest:
Dockerfile.assisted-installer-controller-downstreamline 17Dockerfile.assisted-installer-controller-mceline 20Dockerfile.assisted-installer-downstreamline 17Dockerfile.assisted-installer-mceline 20
Then update the renovate.json regex matcher at lines 92–105 to match the tag without requiring a digest suffix. The current regex requires @sha256:[a-f0-9]+ and will not match plain :latest.

💡 Result:
The Red Hat Universal Base Image (UBI) minimal images, including ubi-minimal and specialized variants like ubi-minimal-pqc, default to the root user [1][2]. Standard UBI minimal images are designed as general-purpose base images and do not automatically enforce a non-root user by default in the image metadata [1][3]. While security best practices for containerization strongly recommend running processes as a non-root user to adhere to the principle of least privilege, developers using these images are responsible for configuring a non-root user within their Containerfile or via the container runtime [3]. The ubi-minimal-pqc image is a variant of the UBI 9 minimal image that includes support for Post-Quantum Cryptography (PQC) in OpenSSL [4]. Like other UBI 9 minimal images, it follows the standard UBI user configuration, which defaults to root [1][4]. If your application requires running as a non-root user, you should define a specific user in your Dockerfile or Containerfile, for example: USER 1001 For environments requiring hardened, non-root-by-default images, Red Hat provides separate "Red Hat Hardened Images," which are distinct from the standard UBI offerings and are specifically configured to enforce non-root execution [3].

Declare a non-root runtime user in all four Dockerfiles.
The pinned ubi-minimal-pqc image defaults to root. Add USER 1001 to each runtime stage after the package-installation RUN instruction. Update the pull-secret permissions or pod security context if UID 1001 must read the mounted token.
