Switching the Raspberry Pi WordPress Site to Hugo

Thu, 09 Jul 2026 00:00:00 +0900

I already wrote about migrating the article data from WordPress to Hugo in Migrating from WordPress to Hugo.

This article covers the next step: switching the actual WordPress environment running on my Raspberry Pi to Hugo.

Even when I built the environment myself, I forget the details after enough time passes. Looking back at my older notes, this site was not running WordPress directly on the host with PHP and MySQL. It was running through Docker.

A Quick Way to Install WSL2 (Ubuntu) and Docker Desktop on Windows 11

Thu, 03 Aug 2023 12:13:54 +0900

This is a note from installing WSL and Docker Desktop in a Windows 11 Pro environment.

Overview

When using Docker containers on Windows, I use Docker Desktop.
For paid licensing and various other reasons, it seems people are moving away from Docker, but it is still easy and convenient when you want to verify something quickly.

On Windows 10, setting up WSL took a bit of work, but recent Windows 11 versions seem to install it quickly, so I wanted to try it.

[Raspberry Pi 4] USB Boot: Stop Using an SD Card and Boot from an SSD

Thu, 06 Jan 2022 17:12:07 +0900

This is a memo from migrating a Raspberry Pi web server that had been running from an SD card to an SSD with USB boot. I had written about something similar before; this time only the data-copying method is different. This procedure may be easier.
The steps are for Ubuntu, but I think almost the same method can be used with Raspberry Pi OS. This is amateur work, so follow it at your own risk if you use it as a reference.

[Raspberry Pi 4] Four-Channel Terrestrial Digital Recording Server on a Raspberry Pi: Docker + GPU Encoding Version

Sat, 18 Sep 2021 08:30:00 +0900

This is a memo for enabling hardware encoding in EPGStation running on a Raspberry Pi. It continues from the previous article, [Raspberry Pi 4] Four-Channel Terrestrial Digital Recording Server on Ubuntu with PX-Q1UD. Some parts still do not work perfectly, but the GPU appears to be usable, and it is mostly operational now.

This is amateur work, so follow it at your own risk if you use it as a reference.

[Raspberry Pi 4] Install Docker on the 64-bit Version of Raspberry Pi OS

Tue, 14 Sep 2021 13:51:47 +0900

This is a memo. It is the same procedure as installing on Ubuntu. The repository URL is about the only difference.

Test Environment

Raspberry Pi 4, 8GB memory
*On this site, I use a SanDisk SSD and a Buffalo SSD for storage. (Reference: [Raspberry Pi 4] Change the Pi 4 Storage from an SD Card to an SSD)

[Raspberry Pi 4] Four-Channel Simultaneous Terrestrial Digital TV Recording Server on Ubuntu with PX-Q1UD

Sat, 19 Jun 2021 00:21:28 +0900

These are notes. I tried something called a recording server. Since I already had a Docker environment, it was easy to create. I also tried hardware encoding, but it was not stable, so these notes only cover building the normal setup. This is amateur work, so if you use it as a reference, do so at your own risk.

Update: In a separate article, I wrote about operating it with H/W encoding.
