Install Docker and Docker Compose on Linux and post-installation

This is just a curated list of resources of how to install docker and docker compose on linux from docker official documentation. I recently installed docker twice on my centos server so I think it is worth noting it down for future use.

Docker installation and post-installation:

• Install Docker Engine for linux
• Post-installation steps for linux

Docker daemon configuration

Daemon configuration Change data-root parameter to a custom path. Change registry-mirrors to another public or private servers. Here’s my sample config file:

"data-root":"/my/path/docker",
"registry-mirrors": [
    "https://hub-mirror.c.163.com",
    "http://registry.docker-cn.com",
    "http://docker.mirrors.ustc.edu.cn",
    "https://ghcr.io",
    "https://mirror.baidubce.com"
  ]
}

Start docker engine

sudo dockerd --debug

Install docker compose V2

Current latest release for V2 is v2.0.1, just follow instructions below to install it: Docker compose v2 installation

Alternatively, docker compose can be installed via pip(python’s package manager). It’s not recommended to go to this route because it may cause problem when you try to uninstall docker and docker compose.
