High level design

The goal of the system is to be a workstation, using rpm-ostree for the base OS, and a combination of Docker and Flatpak containers, as well as virtualization tools such as Vagrant.

Status

This project is actively maintained and is ready for use by sophisticated and interested users, but not ready for widespread promotion.

Installing (do not use partitioning defaults!)

Important! Don't choose auto-partitioning in the below installer ISO; you currently can't use a separate /home partition, and Anaconda defaults to that. This will be fixed in Fedora 27; see this known issue as well as this anaconda PR.

There are ISOs available for Fedora 26 direct link and rawhide.

Important issues:

• Anaconda autopartitoning - be sure to use /var/home instead of /home
• flatpak system repo

Migrating between OSTree repos

Enable the 26/27 remotes:

ostree remote add --if-not-exists --gpg-import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-26-primary fedora-ws-26 https://kojipkgs.fedoraproject.org/compose/ostree/26
ostree remote add --if-not-exists --gpg-import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-27-primary fedora-ws-27 https://kojipkgs.fedoraproject.org/compose/ostree/rawhide

Rebase to rawhide:

rpm-ostree rebase fedora-ws-27:fedora/rawhide/x86_64/workstation

Using the system

First, try out rpm-ostree install to layer additional packages. For example, rpm-ostree install powerline.

Next, let's try flatpak. Before you do: There's a known flatpak issue on AtomicWS - run this workaround, which you only need to do once. After that, try flatpak.

If you are a developer for server applications, try oc cluster up to create a local OpenShift v3 cluster.

Finally, you'll likely want to make one or more "pet" Docker containers, potentially privileged, and use dnf/yum inside these. You can use e.g. -v /srv:/srv so these containers can share content with your host (such as git repositories). Note that if you want to share content between multiple Docker containers and the host (e.g. your desktop session), you should execute (once):

sudo chcon -R -h -t container_file_t /var/srv

Future work

• GNOME Software support for both rpm-ostree/flatpak and possibly docker
• automated tests that run on this content
