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] Headless Install of 64-bit Raspberry Pi OS (No Monitor or Keyboard Needed)

Fri, 17 Sep 2021 00:24:18 +0900

I only recently noticed that Raspberry Pi OS has a 64-bit version, so I will install it on a Raspberry Pi 4. As usual, this assumes no keyboard, mouse, or display is connected to the Raspberry Pi.

Like when installing Ubuntu, this records the steps up to installing the OS and logging in from the host PC (Windows) over SSH. This time I use an SSD for storage instead of an SD card.

[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.

[Raspberry Pi 4] Install Docker on Ubuntu Server 21.04

Tue, 08 Jun 2021 02:10:55 +0900

This is a memo. Since Ubuntu Hirsute 21.04 is already installed on the Raspberry Pi, installing Docker only requires following the procedure on the official site.

Test Environment

Raspberry Pi 4, 4GB memory

Ubuntu Server 21.04

Install Docker

# 旧バージョン等のクリーンアップ
$ sudo apt-get remove docker docker-engine docker.io containerd runc

# Set up the repository
$ sudo apt-get update
$ sudo apt-get install -y 

apt-transport-https 

ca-certificates 

curl 

gnupg

[Raspberry Pi 4] Headless Installation of Ubuntu Server 21.04 Over Wi-Fi Only (No Monitor or Keyboard) 🐣 Beginner-Friendly 🐣
Mon, 07 Jun 2021 11:48:41 +0900
I got a 4 GB memory version of the Raspberry Pi 4, so I tried a headless installation of Ubuntu Server 21.04. For now, I will record the steps from installing the OS to logging in by SSH from the host PC.
Environment Tested
Raspberry Pi 4, 4 GB memory
Transcend microSD 128GB










Write the Ubuntu Image to the SD Card
Prepare the environment on the host PC.
Write Ubuntu to the SD card from Windows, Mac, or Linux.


[Raspberry Pi 4] Run WordPress with Docker
Sat, 13 Mar 2021 13:19:49 +0900
Overview
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.

[Raspberry Pi 4] Build a Mail Server (Postfix + Dovecot) with Docker
Tue, 02 Feb 2021 09:55:54 +0900
This time, I use Docker to start a mail server and handle the various settings around it.
Overview
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.

Overview
Since I installed Ubuntu 20.10 on a Raspberry Pi 4, I migrated the mail server and WordPress running on my current home server over to the Raspberry Pi. These are my notes.
Environment Tested
Raspberry Pi 4 Ubuntu 20.10 (arm64)
$ nginx -v
nginx version: nginx/1.18.0 (Ubuntu)
$ certbot --version
certbot 1.11.0
Prerequisites and Preparation
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.


[Raspberry Pi 4] Headless Installation of Ubuntu 20.10: Installing Without a Keyboard or Display
Tue, 12 Jan 2021 08:07:00 +0900
Overview
This is about installing Ubuntu 20.10 on a Raspberry Pi 4. I did not have a MicroHDMI cable, so I installed and performed the initial setup without connecting a keyboard or display.
I install Ubuntu and make it possible to log in by SSH from a PC, while using the Cloud-init (user-data) mechanism so that as little work as possible is needed after boot.
In a previous article, after installing and booting Ubuntu, various settings still had to be done. This procedure automates that part: [Raspberry Pi 3] Installing Ubuntu 18.04 LTS (no keyboard or display required)


[Raspberry Pi 3] How to Change Only the Ubuntu Username Without Changing the User ID (uid)
Sat, 14 Mar 2020 20:09:17 +0900
This continues from [Raspberry Pi 3] Installing Ubuntu 18.04 LTS (No Keyboard or Display Required).
Leaving the user and password as ubuntu/ubuntu is dangerous, so this is about changing them for now.
Creating a new user and then deleting the ubuntu user would be fine too, but I tried changing only the name while keeping uid=1000 and gid=1000.
Test Environment
Raspberry Pi 3
Ubuntu 18.04.04 LTS 32-bit
How to Do It
You need to log in as root before doing the work, so it may be a little more troublesome than adding a new user and deleting the ubuntu user.

Add the Japanese Locale to Ubuntu 19.10
Sat, 07 Dec 2019 13:56:23 +0900
Even if you set LANG=ja_JP.UTF-8, if the locale definition does not exist you will see error messages like the following.
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory 
Add the Japanese locale with the locale-gen command.
$ sudo locale-gen ja_JP.UTF-8
You can see that it has been added.
