Steps to Install Docker on Manjaro 18

Step 1. Update Manjaro

sudo pacman -Syu

This process could take few minutes, depends on the internet speed.

Step 2. Install Docker

Use this command to install Docker

sudo pacman -S docker

:: Proceed with installation? [Y/n]

Press Y and then Enter, to confirm the installation. After sometimes, Docker should be installed on your Manjaro system. Now run and enable Docker on startup.

sudo systemctl start docker
sudo systemctl enable docker

Check Docker version

sudo docker version

It should return something like this

[dhani@dhani-pc ~]$ sudo docker version

API version: 1.37
Go version: go1.10.2

Done. At this point, Docker is installed on Manjaro.

Step 3. Configure Docker user

By default, only user with root or sudo privileges can run or manage Docker. If you want to run docker without root privileges or without having to add sudo everytime, do the following

sudo usermod -aG docker $USER

Then, reboot Manjaro. 

Upon reboot, you can run docker commands without having to switch to root user or use sudo anymore. You can run with the current user privilege.
