With the use of *Linux Containers* (LXC_) we can scale our tasks over a stack of
containers, what we call the: *lxc suite*. Before you can start with
containers, you need to install and initiate LXD_ once::
$ snap install lxd
$ lxd init --auto
The *searx suite* (:origin:`lxc-searx.env <utils/lxc-searx.env>`) is loaded by
default, every time you start the ``lxc.sh`` script (you do not need to care
about). To make use of the containers from the *searx suite*, you have to build
the :ref:`LXC suite containers <lxc.sh --help>` first. But be warned, this
might take some time::
$ sudo -H ./utils/lxc.sh build
A cup of coffee later, your LXC suite is build up and you can run whatever task
you want / in a selected or even in all :ref:`LXC suite containers <lxc.sh
--help>`. Each container shares the root folder of the repository and the
command ``utils/lxc.sh cmd`` handles relative path names *transparent*::
$ sudo -H ./utils/lxc.sh cmd -- ls -la Makefile
...
[searx-ubu2004] -rw-r--r-- 1 root root 7603 Mar 30 11:54 Makefile
[searx-fedora31] -rw-r--r-- 1 root root 7603 Mar 30 11:54 Makefile
[searx-archlinux] -rw-r--r-- 1 root root 7603 Mar 30 11:54 Makefile
With this in mind, you can run :ref:`searx.sh` and install packages, needed by
searx::
$ sudo -H ./utils/lxc.sh cmd -- ./utils/searx.sh install packages
And run one of the :origin:`Makefile` targets::
$ sudo -H ./utils/lxc.sh cmd -- make test.sh
You can install a *buildhost environment* into the containers (time for another
cup of coffee)::
$ sudo -H ./utils/lxc.sh install buildhost
If you want to get rid off all the containers, just type::
$ sudo -H ./utils/lxc.sh remove
To clean up your local images use::
$ sudo -H ./utils/lxc.sh remove images
.. _lxc.sh --help:
Overview
========
The ``--help`` output of the script is largely self-explanatory:
.. program-output:: ../utils/lxc.sh --help
