Rocky Linux Ostree
This repository contains all the bits to get a working Ostree for Rocky Linux (8.6). Although Fedora and Red Hat CoreOS use (rpm)Ostree, this is NOT a CoreOS clone.
If you want to build a Rocky Linux CoreOS, in other words a Red Hat CoreOS clone, then checkout coreos-assembler. Other sites with information about CoreOS and building custom OStree(s):
Especially osbuild is a very nice project/tool which is now incorperated in the more recent Red Hat versions.
Dir: bootserver
Contains an Ansible playbook to configure a PXE bootserver
Dir: ostree-config
Contains the config files to build a basic Ostree for Rocky Linux
How to use
From the root directory of this project:
- Create a build directory with the repo and cache directory below it. The repo directory will have the final OStree repository where you could boot from.
- Initialize the ./build/repo directory as a OStree repository
- Build the OStree repo
mkdir -p ./build/{repo,cache}
ostree --repo=./build/repo init --mode=archive
sudo rpm-ostree --unified-core compose tree --cachedir=./build/cache --repo=./build/repo config/manifest.yaml
When the compose state is finished, rsync the repo to the bootserver and network boot from it.
sudo rsync -av --delete ./build/repo root@192.168.122.89:/var/www/html/ostree/
