Docker install via Snap

Often I forget steps required to install docker via snap. Here are the steps for record-keeping purpose:

Preparation

$ sudo apt-get update

Install docker

Install command: $ sudo snap install docker
Test: $ docker --version would show something like: Docker version 19.03.11, build dd360c7

Post-install task

From an archived this url, follow these steps:

Create and join the docker group:

• $ sudo addgroup --system docker
• $ sudo adduser $USER docker
• $ newgrp docker

Restart

• $ sudo snap disable docker
• $ sudo snap enable docker

Test

docker --rm -p 80:80 seoul4/hostnameprint
