==== 3.1 Install Docker ====

<ol style="list-style-type: decimal;">
<li><p>'''Verify Existing Docker Installation:'''</p>
<p>Run the command to check if Docker is installed: <code>docker --version</code>. Make sure the version is 24.0.0 or later. If it’s an older version, remove it by using:</p>
<pre>sudo apt remove docker docker-engine docker.io containerd runc</pre></li>
<li><p>'''Install the Latest Version of Docker:'''</p>
<p>Download and install Docker using the official installation script. Run:</p>
<pre>curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh</pre></li></ol>

<blockquote>'''Note:''' Use the official Docker installation, not the Snap version. The Snap version is [https://www.reddit.com/r/docker/comments/shztqs/wow_docker_works_a_lot_better_when_you_dont_have/ ''horrible''] &amp; causes tons of issues. If you got tricked into installing Docker at the end of the Ubuntu server installation prompts, I am sorry, but you have to remove that, it’s garbage. Run <code>sudo snap remove docker</code> and never look back.

<ol start="3" style="list-style-type: decimal;">
<li><p>'''Install Docker Compose:'''</p>
<pre>sudo apt install docker-compose-plugin -y</pre></li>
<li><p>'''Verify Docker Compose Installation:'''</p></li>
<li><p>Make sure Docker Compose version is 2.0 or higher by running:</p>
<pre>docker compose version</pre></li>
<li><p>'''Set Proper Permissions for Docker:'''</p>
<ul>
<li><p>Docker typically requires root permissions, but you can add your user to the Docker group to avoid using <code>sudo</code>. Run:</p>
<pre>sudo usermod -aG docker $USER</pre></li>
<li><p>Log out and log back in, or run:</p>
<pre>newgrp docker</pre></li></ul>
</li></ol>
