rpm-ostree Overview

New! See the docs online at Read The Docs (rpm-ostree)

---

rpm-ostree is a hybrid image/package system. It uses OSTree as an image format, and uses RPM as a component model.

The project aims to bring together a hybrid of image-like upgrade features (reliable replication, atomicity), with package-like flexibility (introspecting trees to find package sets, package layering, partial live updates).

Features:

• Atomic upgrades and rollback for host system updates
• A server side tool to consume RPMs and commit them to an OSTree repository
• A system daemon to consume ostree commits as updates

Projects using rpm-ostree

Project Atomic uses rpm-ostree to provide a minimal host for Docker formatted Linux containers. Replicating a base immutable OS, then using Docker for applications.

Building

Releases are available as GPG signed git tags, and most recent versions support extended validation using git-evtag.

However, in order to build from a git clone, you must update the submodules. If you're packaging and want a tarball, I recommend using a "recursive git archive" script. There are several available online; this code in OSTree is an example.

Once you have a git clone or recursive archive, building is the same as almost every autotools project:

env NOCONFIGURE=1 ./autogen.sh
./configure --prefix=...
make
make install DESTDIR=/path/to/dest
