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, the next step is to install the build dependencies. At the moment, rpm-ostree has a hard requirement on a bleeding edge version of libhif. It also requires a few other libraries like librepo.

Once you have the dependencies, building is the same as every autotools project:

env NOCONFIGURE=1 ./autogen.sh
./configure --prefix=/usr --libdir=/usr/lib64 --sysconfdir=/etc
make

At this point you can run some of the unit tests with make check. For more information on this, see CONTRIBUTING.md.
