Base images

This repository contains recipies (Containerfiles/Dockerfiles) for building base images for use in SPK.

The container images are currently built using podman on internal GitHub Runners.

⚙️ Containerfile customisation

The Containerfiles take advantage of the ARG instruction to allow for customisation of the build process. Inspect each Containerfile for the available arguments.

🪨 Rocky Linux 8, 9, and 10

Based on the latest rockylinux images. Primarily used as base images for other images. We set the timezone to Europe/Oslo and install internal SPK root CA certificates, as well as adding, but not enabling, internal Yum repositories.

Available versions:

• 8
• 8-minimal
• 9
• 9-minimal
• 10
• 10-minimal

Yum repositories

As default, only standard external yum repositories are enabled, no internal SPK repos. That means you can use it on cloud runners.

If you need to install SPK-RPMs, you need to build on our internal runners, enable the SPK repos, and disable the mirrorlist in the standard repos. The repo config can be done by running the script yum-switch-to-internal-repos.sh in your build file, as root, before dnf install.
