Base images

This project closely tracks CentOS and Fedora, and aims to tightly integrate with their underlying lifecycle as well as release and test infrastructure, and in particular the CentOS Stream versions are the upstream for the RHEL product.

These are the default "full" images:

  • CentOS Stream 9: quay.io/centos-bootc/centos-bootc:stream9 (source repo)

  • Fedora: quay.io/fedora/fedora-bootc:41 (source repo)

  • CentOS Stream 10 (in development): quay.io/centos-bootc/centos-bootc:stream10 (source repo)

For RHEL, see RHEL 9 Image Mode. Note that at the current time the RHEL product is Tech Preview status and this is also true of the upstream; the contents and interfaces of the base images are still subject to change.

"full" image philosophy

The content set for the default images are intentionally quite large.

  • bootc: Included in the container to perform in-place upgrades "day 2"

  • kernel: There’s a kernel

  • systemd: systemd is included and is configured to run by default when executed as a container too

  • NetworkManager: Full support for many complex networking types

  • podman: Support for OCI containers

  • Filesystem tools, support for LUKS, LVM, RAID etc.

  • Lots of other supporting tools, such as sos, jq etc.

No cloud agents by default

However, the image does not include hypervisor specific agents. You may install them in derived builds. For example, on Amazon Web Services, you may want to install cloud-init; but this is also not required.

See Cloud agents for more information.

"minimal" image philosophy

There are also demonstration images that are much smaller that are intended to be used more as a development reference. These images are not currently published on Quay.io but are available in the GitLab container registry.

This image has almost nothing; just kernel systemd bootc; everything else (including e.g. networking) you need to add.
