Docker Setup

Install​

Follow Docker Installation Guide via this LINK

Setup​

Start docker-client and set automatically start on boot Docker

sudo systemctl start docker && sudo systemctl enable docker

Containerd

sudo systemctl start containerd && sudo systemctl enable containerd

To stop this behavior, use disable instead.

sudo systemctl disable docker
sudo systemctl disable containerd

Run Docker Without Sudo​

You can set up the Docker daemon to run without root privileges. This is a good way to avoid using sudo when you use the docker command.
Directly use the following script for a quick setup, or follow the steps below for manual operation.

warning

Membership in the docker group is effectively equivalent to root access because Docker can mount host filesystems and run privileged containers. Add only trusted users to this group.

Quick Setup​

WGET

wget -N --no-cache --no-check-certificate https://carry0987.github.io/Linux-Note/data/Docker/docker-setup.sh && chmod +x docker-setup.sh && bash docker-setup.sh

CURL

curl -H 'Cache-Control: no-cache' -O https://carry0987.github.io/Linux-Note/data/Docker/docker-setup.sh && chmod +x docker-setup.sh && bash docker-setup.sh
