Lapwing.Org: Sponson
====================

About
=====

Sponson is a tool to create and setup ``systemd-nspawn`` containers
in a Docker-like way, without using Docker.


Requirements
============

- python3 >= 3.5
- Linux kernel >= 4.2 with ``overlayfs`` support
- Python3 DBUS bindings, provided by ``dbus-python``
- Python3 gobject bindings, provided by ``python3-gobject``
- systemd >= 234
- dnsmasq
- firewalld
- ostree
- lsof


For Fedora 27 Workstation, run
``dnf install systemd-container ostree lsof``

For Fedora 27 Cloud, run
``dnf install firewalld dnsmasq python3-gobject systemd-container ostree lsof``


nsswitch.conf
=============

To be able to connect with containers from the host,
`/etc/nsswitch.conf` requires `mymachines` in the `hosts` line,
for example

.. code::

   hosts: files dns mymachines


selinux
=======

If ``selinux`` is installed and enabled,
you will need to import a module to allow
sponson to setup the firewall when bringing up a container.

    sudo semodule -i {path to sponson}/selinux/sponson.pp

If the module does not import,
you can build the module using

    checkmodule -M -m -o {path to sponson}/selinux/sponson.mod {path to sponson}/selinux/sponson.te

    semodule_package -o {path to sponson}/selinux/sponson.pp -m {path to sponson}/selinux/sponson.mod

    sudo semodule -i {path to sponson}/selinux/sponson.pp

Fedora 25+ also seems to have faults with `machinectl` accessing `/var/lib/machines`,
so you might want to also use the provided `systemdmachine.pp`.
