Raspberry Pi is quite a utility featuring small size, ARM processor, and decent RAM. Power consumption is low. The device performs substantial work and enables several people to try new technologies affordably.
We are going to cover the steps for the full Docker experience on a RPi. A few steps are needed to set up the environment correctly.
After you have flashed the latest OS onto a MicroSD, we will want to connect a keyboard and screen to the device.
Once you have booted into the OS, we will want to make sure things are up-to-date.
sudo apt update && sudo apt full-upgrade && sudo apt autoremove && sudo apt autocleanNow we will want to add a key ring to be able to install Log2RAM. This utility saves the life of your MicroSD by making sure minimal amounts of write activity happens on the card. If you haven’t read it elsewhere, MicroSD are nice, but they are not know for their lifespan. The main thing that kills them is frequent and persistent writes of data from log files and the like.
echo "deb [signed-by=/usr/share/keyrings/azlux-archive-keyring.gpg] http://packages.azlux.fr/debian/ $(bash -c '. /etc/os-release; echo ${VERSION_CODENAME}') main" | sudo tee /etc/apt/sources.list.d/azlux.list && sudo wget -O /usr/share/keyrings/azlux-archive-keyring.gpg https://azlux.fr/repo.gpg && sudo apt update && sudo apt install log2ramNow, for Docker itself we have an easy one-liner to get it installed. Some do not like to run these, but as this is from “docker.com” it should be trustworthy and with the extra steps and difficulty involve this is the easiest way to get Docker setup swiftly.
curl -sSL https://get.docker.com | shTo be able to use Docker as the logged in user however, you will need to add your use to the “docker” group.
sudo usermod -aG docker $USER
