Manage systemd-nspawn containers
--------------------------------
:manual section: 7
:manual group: Open Infrastructure
Description
===========
[A Linux container] is an operating-system-level virtualization environment for
running multiple isolated Linux systems (containers) on a single Linux control
host.
-- Wikipedia (https://en.wikipedia.org/wiki/LXC)
**compute-tools** provides the system integration for managing containers using
systemd-nspawn(1).
Download

Installation
============
Source
------
| $ sudo apt install git make python3-docutils dbus systemd-container
| $ git clone https://git.open-infrastructure.net/software/compute-tools
| $ cd compute-tools && sudo make install

| $ sudo apt install compute-tools
Development
===========
Bug reports, feature requests, help, patches, support and everything else are
welcome on the Open Infrastructure Software Mailing List
(https://lists.open-infrastructure.net/listinfo/software).
Please base patches against the 'next' Git branch using common sense
(https://www.kernel.org/doc/Documentation/SubmittingPatches).
Debian specific bugs can also be reported in the Debian Bug Tracking System
(https://bugs.debian.org).
Known limitations
=================
This version of compute-tools currently do not work with systemd-networkd and
depend on ifupdown.
Using overlay, the upper directory can not be an NFS mount due to limitations in
Linux' overlay filesystem
(https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/filesystems/overlayfs.txt).
Usage
=====
Build a new container:
sudo container build -n NAME
Start a container:
sudo container start -n NAME
Stop a container:
sudo container stop -n NAME
Remove a container:
sudo container remove -n NAME
List container on the system:
sudo container list
Show container version:
container version
See container(1) for a list of all container commands.
