Cheatsheet for docker

Configure Docker to start on boot

Most current Linux distributions (RHEL, CentOS, Fedora, Debian, Ubuntu 16.04 and higher) use systemd to manage which services start when the system boots. On Debian and Ubuntu, the Docker service is configured to start on boot by default. To automatically start Docker and Containerd on boot for other distros, use the commands below:

 sudo systemctl enable docker.service

 sudo systemctl enable containerd.service

To disable this behavior, use disable instead.

 sudo systemctl disable docker.service

 sudo systemctl disable containerd.service

If you need to add an HTTP Proxy, set a different directory or partition for the Docker runtime files, or make other customizations, see customize your systemd Docker daemon options.
