Install Docker on Raspberry Pi

Posted on by

This article explains how to install Docker on a Raspberry Pi, how to build a simple image, and how to run a container based on it.

Update 20/9/22: This procedure has been updated and tested successfully on RaspiOS “Bullseye”, release date 2022-09-06 (lite version).

Docker provides a mobile execution environment in which to run software. It is a very popular container technology. Docker is useful in the rapid deployment of applications and in application isolation. It is a valuable tool for developers, users and systems administrators. In this procedure, it will be used to install a simple video processing application called “comskip“.

Although the article is entitled Install Docker on Raspberry Pi, this procedure will work unaltered on most Linux distros, which is one of the advantages of Docker.

Besides acting as a demonstration for those wanting to learn about Docker, this article is aimed at readers of my previous articles How to Watch and Record Live TV with a Raspberry Pi and How to Install Comskip on a Rasperry Pi (without Docker).

Raspberry Pi 4 Real World Tests

The Raspberry Pi 4 was launched on 24th June and has been well received, to say the least. The spec is a big step up on previous models. It has 4 CPU cores like the Pi 2, a gigabit port like the Pi 3, plus USB 3, a better SoC, a separated bus architecture, faster memory and more of it.

Over the years, many “home” devices have been launched with Gigabit Ethernet, promising lightning fast network speeds, only to disappoint due to their lack of overall grunt. The Linkstation Live, the Sheevaplug and, to a lesser extent the Pi 3 are all on that category, unable to push their gigabit ports to more than about 14, 8 and 12 megabytes/sec respectively, due to the limitations of the CPU and the board. Is the Pi 4 the same, or can it operate as a serious NAS ?

Short answer: Yes. The Pi 4 is a *serious* NAS contender. Sustained write speeds of over 68 MB/s were obtained, and over 105 MB/s for reading, including saturation of the Gigabit network. Yes, the Pi 4 can push even a 1000 MB/s network to 100%.

In need of some network storage in the home ? Well, you could go off and buy a proper NAS unit, offering RAID, several Tb of storage, fast access speeds and so on. On the other hand, you might have something lying round the house that will do. It won’t be as good as a proper NAS, but it might just be good enough. Continue reading →

Mounting BT Home Hub 3 USB on WD TV Live

This post may be of interest to UK users who own both a BT Home Hub 3 router and a WD TV Live media streamer. Both are Linux based systems, but getting one to work with the other can be a bit of a challenge.

The USB port on the back of the Home Hub 3 can be used to share storage over the network. Plug in a disk or memory stick, and it is automatically shared out as a windows share. Using a large capacity memory stick offers the possibility of NAS like, always-on access to your media files from any connected device. Low power consumption too. This post explains how access the USB connected drive from the WD TV Live. Continue reading →
