&lt;p&gt;These are notes from setting up WordPress with Docker. Nginx is already running on the host side, and an SSL certificate has already been obtained, so WordPress will ride on that setup too.&lt;/p&gt;

&lt;h2&gt;Overview&lt;/h2&gt;
&lt;p&gt;I use Postfix and Dovecot for my home mail server, but when installed as native packages, the initial configuration is complicated. When rebuilding the server or moving it to another PC, I completely forget what was configured and how. On top of that, I also need to configure other tools such as spam countermeasures and Fail2Ban, so it is a real hassle. This time the goal is an easy installation using Docker.&lt;/p&gt;</description></item><item><title>[Raspberry Pi 4] Install Nginx and Obtain an SSL Server Certificate from Let's Encrypt</title><link>https://nosubject.io/en/raspberry-pi4-nginx-letsencrypt/</link><pubDate>Sat, 23 Jan 2021 17:54:14 +0900</pubDate><guid>https://nosubject.io/en/raspberry-pi4-nginx-letsencrypt/</guid><description>&lt;h2&gt;Overview&lt;/h2&gt;
&lt;p&gt;Since I &lt;a href="https://nosubject.io/raspberry-pi4-ubuntu-20-10-headless-install/" title="[Raspberry Pi 4] Headless installation of Ubuntu 20.10. How to install without a keyboard or display" target="_blank" rel="noreferrer noopener"&gt;installed Ubuntu 20.10 on a Raspberry Pi 4&lt;/a&gt;, I migrated the mail server and WordPress running on my current home server over to the Raspberry Pi. These are my notes.&lt;/p&gt;
&lt;h3&gt;Environment Tested&lt;/h3&gt;
&lt;p&gt;Raspberry Pi 4 Ubuntu 20.10 (arm64)&lt;/p&gt;
&lt;p&gt;$ nginx -v&lt;br&gt;nginx version: nginx/1.18.0 (Ubuntu)&lt;/p&gt;
&lt;p&gt;$ certbot --version&lt;br&gt;certbot 1.11.0&lt;/p&gt;
&lt;h3&gt;Prerequisites and Preparation&lt;/h3&gt;
&lt;p&gt;Complete the Ubuntu installation, PPPoE settings, and domain settings in advance. This is the same as what I did previously on the Pi 3, so I will omit the details.&lt;/p&gt;</description></item></channel></rss>
