Let's put Docker in Manjaro installed on Raspberry Pi 4 and set up some server. It's my first Arch system and I'm embarrassed and nervous.
$ lsb_release -rd Description: Manjaro ARM Linux Release: 20.09
$ sudo pacman -S docker $ docker --version Docker version 19.03.12-ce, build 48a66213fe
$ sudo usermod -aG docker `whoami`
I wanted to do
systemctl start docker without rebooting, but it didn't start at all.
After restarting with
systemctl enable docker, it was easy, so this is fine.
$ sudo systemctl enable docker $ sudo reboot
$ sudo pacman -S docker-compose $ docker-compose --version docker-compose version 1.27.3, build unknown
The package is quite substantial.
