rpm-ostree
|
|
==========
|
|
|
|
This tool takes a set of packages, and commits them to an
|
|
[OSTree](https://wiki.gnome.org/Projects/OSTree) repository. At the
|
|
moment, it is intended for use on build servers.
|
|
|
|
Major changes since 2014.8
|
|
--------------------------
|
|
|
|
The previous major release of this program contained within it an
|
|
"autobuilder" codebase which had significant functionality beyond just
|
|
composing trees, such as creating VM disk images and running
|
|
smoketests.
|
|
|
|
Since that time, the other functionality has moved to:
|
|
https://github.com/cgwalters/rpm-ostree-autocompose
|
|
|
|
This program now only commits trees to a repository, using "treefiles"
|
|
which are very simple JSON input data.
|
|
|
|
Installing and setting up a repository
|
|
--------------------------------------
|
|
|
|
First, unfortunately you must *disable* SELinux on the build host in
|
|
order to *support* SELinux on the built system. See:
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1060423
|
|
|
|
Second, you must install `nss-altfiles` on the host system, and
|
|
edit your /etc/nsswitch.conf to include `altfiles`, like this:
|
|
|
|
passwd: files altfiles
|
|
group: files altfiles
|
|
|
|
You may or may not be using SSSD (and thus the `sss` option); if you
|
|
are then it should look like:
|
|
|
|
passwd: files altfiles sss
|
|
group: files altfiles sss
|
|
|
|
For more information, see:
|
|
http://lists.rpm.org/pipermail/rpm-maint/2014-January/003652.html
|
|
|
|
There are packages available in the rpm-ostree COPR:
|
|
http://copr-fe.cloud.fedoraproject.org/coprs/walters/rpm-ostree/
|
|
|
|
At the moment, all of the tooling except for the patched
|
|
`shadow-utils` is in Fedora rawhide.
|
|
|
|
Once you have that done, choose a build directory. Here we'll use
|
|
/srv/rpm-ostree.
|
|
|
|
# cd /srv/rpm-ostree
|
|
# mkdir repo
|
|
# ostree --repo=repo init --mode=archive-z2
|
|
|
|
Running rpm-ostree
|
|
------------------
|
|
|
|
The core "rpm-ostree" takes as input a "treefile". See examples in
|
|
`doc/treefile-examples`.
|
|
|
|
# rpm-ostree treecompose --repo=/srv/rpm-ostree/repo --proxy=http://127.0.0.1:8123 sometreefile.json
|
|
|
|
All this does is use yum to download RPMs from the referenced repos,
|
|
and commit the result to the OSTree repository, using the ref named by
|
|
`ref`. Note that we've specified a local caching proxy (`polipo` in
|
|
this case) - otherwise we you will download the packages for each
|
|
treecompose.
|
|
|
|
You can export `/srv/rpm-ostree/repo` via any static webserver.
