<p>There is a conflict in the <code class="docutils literal notranslate"><span class="pre">iptables</span></code> setup of Docker & 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>

|

|
|
</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>

<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

|

<em>archlinux</em> image:</p>
|
|||
|
|
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ sudo -H ./utils/lxc.sh build searxng-archlinux

|

|
|
<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
