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 (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 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 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 searx.sh and install packages, needed by searx:

$ sudo -H ./utils/lxc.sh cmd -- ./utils/searx.sh install packages

And run one of the 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

Overview

The --help output of the script is largely self-explanatory:

../utils/lxc.sh --help
