Goals

This project’s toplevel goal is to maintain default definitions for base bootable container images, locked with Fedora ELN and CentOS Stream 9.

Status

This is an in-development project not intended for production use yet.

Container images

The primary output of this project is container images. The current main development targets are Fedora ELN and CentOS Stream 9.

Distribution locked images

These images are intended to exactly match the content of the underlying distribution.

quay.io/centos-bootc/fedora-bootc:eln
quay.io/centos-bootc/centos-bootc:stream9

Layered images

There are also layered images; for more information on these, see the centos-bootc-layered repository.

Development images

Some components of this project move quickly, and it’s often useful to see things as they appear in git main instead of waiting for package releases.

The following images track git main of selected components:

quay.io/centos-bootc/fedora-bootc-dev:eln
quay.io/centos-bootc/centos-bootc-dev:stream9

For more information, see the dev repository.

Trying it out

See install.md.

Understanding “tiers”

There is a “tier-0” image, but it is not yet being automatically built. The “tier-0” contains:

kernel
systemd
bootc
selinux-policy-targeted

The tier-1 is a reasonably large system:

NetworkManager, chrony
openssh-server
dnf (for installing packages in container builds)
rpm-ostree (A lot of tooling uses this too)

The content set for these images is subject to change.

Building

Here’s an example command:

sudo rpm-ostree compose image --authfile ~/.config/containers/myquay.json --cachedir=cache -i --format=ociarchive centos-tier-0-stream9.yaml centos-tier-0-stream9.ociarchive

In some situations, copying to a local .ociarchive file is convenient. You can also push to a registry with --format=registry.
