Docker and Docker-compose on Raspberry Pi¶
How to install docker on Raspberry Pi¶
sudo apt install -y docker.io
Runing Docker as root¶
sudo usermod -aG docker pi
Manage Docker as a non-root user¶
The Docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The Docker daemon always runs as the root user.
If you don’t want to preface the docker command with sudo, create a Unix group called docker and add users to it. When the Docker daemon starts, it creates a Unix socket accessible by members of the docker group.
The docker group grants privileges equivalent to the root user.
sudo groupadd docker sudo usermod -aG docker $USER newgrp docker
How to install docker-compose on Raspberry Pi¶
sudo apt install docker-compose
