<p>With the use of <em>Linux Containers</em> (<a class="reference external" href="https://linuxcontainers.org/lxc/introduction/">LXC</a>) we can scale our tasks over a stack of
containers, what we call the: <em>lxc suite</em>. The <a class="reference internal" href="#lxc-searxng-env"><span class="std std-ref">SearXNG suite config</span></a> is
loaded by default, every time you start the <code class="docutils literal notranslate"><span class="pre">lxc.sh</span></code> script (<em>you do not need

<p>There is a conflict in the <code class="docutils literal notranslate"><span class="pre">iptables</span></code> setup of Docker &amp; LXC. If you have
docker installed, you may find that the internet connectivity of your LXD
containers no longer work.</p>
<p>Whenever docker is started (reboot) it sets the iptables policy for the
<code class="docutils literal notranslate"><span class="pre">FORWARD</span></code> chain to <code class="docutils literal notranslate"><span class="pre">DROP</span></code> <a class="reference external" href="https://docs.docker.com/network/iptables/#docker-on-a-router">[ref]</a>:</p>

:FORWARD ACCEPT [7048:7851230]
:FORWARD DROP [7048:7851230]
</pre></div>
</div>
<p>A handy solution of this problem might be to reset the policy for the
<code class="docutils literal notranslate"><span class="pre">FORWARD</span></code> chain after the network has been initialized. For this create a
file in the <code class="docutils literal notranslate"><span class="pre">if-up</span></code> section of the network (<code class="docutils literal notranslate"><span class="pre">/etc/network/if-up.d/iptable</span></code>)
and insert the following lines:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="ch">#!/bin/sh</span>
<span class="n">iptables</span> <span class="o">-</span><span class="n">F</span> <span class="n">FORWARD</span>
<span class="n">iptables</span> <span class="o">-</span><span class="n">P</span> <span class="n">FORWARD</span> <span class="n">ACCEPT</span>
</pre></div>
</div>
<p>Dont forget to set the execution bit:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">sudo</span> <span class="n">chmod</span> <span class="n">ugo</span><span class="o">+</span><span class="n">x</span> <span class="o">/</span><span class="n">etc</span><span class="o">/</span><span class="n">network</span><span class="o">/</span><span class="k">if</span><span class="o">-</span><span class="n">up</span><span class="o">.</span><span class="n">d</span><span class="o">/</span><span class="n">iptable</span>

<p>Reboot your system and check the iptables rules:</p>

<p>The intention of the <em>SearXNG LXC suite</em> is to build up a suite of containers
for development tasks or <a class="reference internal" href="#setup-searxng-buildhost"><span class="std std-ref">buildhosts</span></a> with a very
small set of simple commands. At the end of the <code class="docutils literal notranslate"><span class="pre">--help</span></code> output the SearXNG
suite from the <a class="reference internal" href="#lxc-searxng-env"><span class="std std-ref">SearXNG suite config</span></a> is introduced:</p>

containers: searxng-ubu2004 searxng-ubu2204 searxng-fedora35 searxng-archlinux
</pre></div>
</div>
<p>As shown above there are images and containers build up on this images. To show
more info about the containers in the <em>SearXNG LXC suite</em> call <code class="docutils literal notranslate"><span class="pre">show</span> <span class="pre">suite</span></code>.
If this is the first time you make use of the SearXNG LXC suite, no containers
are installed and the output is:</p>

<p>If you do not want to run a command or a build in all containers, <strong>you can
build just one</strong>. Here by example in the container that is build upon the

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/lxc.sh build searxng-archlinux
$ sudo -H ./utils/lxc.sh cmd searxng-archlinux pwd

<p>Otherwise, to apply a command to all containers you can use:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/lxc.sh build
$ sudo -H ./utils/lxc.sh cmd -- ls -la .

<p><strong>Inside containers, you can run scripts</strong> from the <a class="reference internal" href="index.html#toolboxing"><span class="std std-ref">DevOps tooling box</span></a> or run
what ever command you need. By example, to start a bash use:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/lxc.sh cmd searxng-archlinux bash

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ pwd

$ sudo -H ./utils/lxc.sh cmd searxng-archlinux pwd
INFO: [searxng-archlinux] pwd
/share/SearXNG
</pre></div>
</div>
<p>The path <code class="docutils literal notranslate"><span class="pre">/share/SearXNG</span></code> will be different on your HOST system. The commands
in the container are executed by the <code class="docutils literal notranslate"><span class="pre">root</span></code> inside of the container. Compare
output of:</p>
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ ls -li Makefile

...
</pre></div>
</div>
<p>Since the path <code class="docutils literal notranslate"><span class="pre">/share/SearXNG</span></code> of the HOST system is wrapped into the
container under the same name, the shown <code class="docutils literal notranslate"><span class="pre">Makefile</span></code> (inode <code class="docutils literal notranslate"><span class="pre">47712402</span></code>) in
the output is always the identical <code class="docutils literal notranslate"><span class="pre">/share/SearXNG/Makefile</span></code> from the HOST
system. In the example shown above the owner of the path in the container is
the <code class="docutils literal notranslate"><span class="pre">root</span></code> user of the container (and the timezone in the container is
different to HOST system).</p>
