<p>Understanding container architecture basics is essential for properly
maintaining your SearXNG instance. This guide assumes familiarity with
container concepts and provides deployment steps at a high level.</p>
<p>If youre new to containers, we recommend learning the fundamentals at
<a class="reference external" href="https://docs.docker.com/get-started/docker-overview">Docker 101</a> before proceeding.</p>
</div>
<p>Container images are the basis for deployments in containerized environments,
Compose, Kubernetes and more.</p>

<span id="container-prerequisites"></span><h3>Prerequisites<a class="headerlink" href="#prerequisites" title="Link to this heading"></a></h3>
<p>You need a working Docker or Podman installation on your system. Choose the
option that works best for your environment:</p>
<ul class="simple">
<li><p><a class="reference external" href="https://docs.docker.com/get-docker/">Docker</a> (recommended for most users)</p></li>
<li><p><a class="reference external" href="https://podman.io/docs/installation">Podman</a></p></li>
</ul>
<p>In the case of Docker, you need to add the user running the container to the
<code class="docutils literal notranslate"><span class="pre">docker</span></code> group and restart the session:</p>

</pre></div>
</div>
<p>In the case of Podman, no additional steps are generally required, but there
are some considerations when running <a class="reference external" href="https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md">Podman rootless containers</a>.</p>

<span id="container-manual-instancing"></span><h2>Manual instancing<a class="headerlink" href="#manual-instancing" title="Link to this heading"></a></h2>
<p>This section is intended for advanced users who need custom deployments. We
recommend using <a class="reference internal" href="#container-compose-instancing">Container compose instancing</a>, which provides a preconfigured
environment with sensible defaults.</p>
<p>Basic container instancing example:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span><span class="c1"># Create directories for configuration and persistent data</span>
$<span class="w"> </span>mkdir<span class="w"> </span>-p<span class="w"> </span>./searxng/config/<span class="w"> </span>./searxng/data/
$<span class="w"> </span><span class="nb">cd</span><span class="w"> </span>./searxng/
<span class="c1"># Run the container</span>
$<span class="w"> </span>docker<span class="w"> </span>run<span class="w"> </span>--name<span class="w"> </span>searxng<span class="w"> </span>-d<span class="w"> </span><span class="se">\</span>

<span class="w"> </span>docker.io/searxng/searxng:latest

<h2>Migrate from <code class="docutils literal notranslate"><span class="pre">searxng-docker</span></code><a class="headerlink" href="#migrate-from-searxng-docker" title="Link to this heading"></a></h2>
<p>We expect the following source directory structure:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>.
└──<span class="w"> </span>searxng-docker
<span class="w"> </span>├──<span class="w"> </span>searxng

</div>
<p>Create a brand new environment outside <code class="docutils literal notranslate"><span class="pre">searxng-docker</span></code> directory, following
<a class="reference internal" href="#container-compose-instancing-setup">Container compose instancing setup</a>.</p>
<p>Once up and running, stop the services and move the configuration files from
the old mount to the new one:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>$<span class="w"> </span>mv<span class="w"> </span>./searxng-docker/searxng/*<span class="w"> </span>./searxng/core-config/

</div>
<p>If using Valkey features like bot protection (limiter), you will need to update
the URL hostname in <a class="extlink-origin reference external" href="https://github.com/searxng/searxng/blob/master/searx/settings.yml">git://searx/settings.yml</a> file to <code class="docutils literal notranslate"><span class="pre">valkey</span></code> or
<code class="docutils literal notranslate"><span class="pre">searxng-valkey</span></code>.</p>
<p>If you have any environment variables in the old <code class="docutils literal notranslate"><span class="pre">.env</span></code> file, make
sure to add them to the new one.</p>
<p>Consider setting up a reverse proxy if exposing the instance to the public.</p>
<p>You should end with the following directory structure:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>.
├──<span class="w"> </span>searxng
<span class="w"> </span>├──<span class="w"> </span>core-config

</div>
<p>If everything is working on the new environment, you can remove the old
