# rpm-ostree Overview

rpm-ostree is a hybrid image/package system. It uses
|
|
[OSTree](https://wiki.gnome.org/Projects/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](http://www.projectatomic.io/) uses rpm-ostree to
|
|
provide a minimal host for Docker formatted Linux containers.
|
|
Replicating a base immutable OS, then using Docker for applications.
|
|
|
|
Using rpm-ostree to build OS images/trees
|
|
-----------------------------------------
|
|
|
|
See [Compose Server](docs/manual/compose-server.md).
|
|
|
|
Building
|
|
--------
|
|
|
|
Releases are available as GPG signed git tags, and most recent
|
|
versions support extended validation using
|
|
[git-evtag](https://github.com/cgwalters/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](https://git.gnome.org/browse/ostree/tree/packaging/Makefile.dist-packaging#n11)
|
|
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](https://github.com/rpm-software-management/libhif/). It also
|
|
requires a few other libraries like
|
|
[librepo](https://github.com/rpm-software-management/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`.
