多种方式安装 Docker

CentOS

To install Docker Engine, you need a maintained version of CentOS 7, CentOS 8 (stream), or CentOS 9 (stream).

## Uninstall old versions
sudo yum remove docker \
                docker-client \
                docker-client-latest \
                docker-common \
                docker-latest \
                docker-latest-logrotate \
                docker-logrotate \
                docker-engine

## Install the yum-utils package (which provides the yum-config-manager utility) and set up the repository.
sudo yum install -y yum-utils
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin
## or
yum list docker-ce --showduplicates | sort -r
## sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io docker-compose-plugin

## Start docker
sudo systemctl start docker

## Enable selfstart
sudo systemctl enable docker

Ubuntu

• Ubuntu Kinetic 22.10
• Ubuntu Jammy 22.04 (LTS)
• Ubuntu Focal 20.04 (LTS)
• Ubuntu Bionic 18.04 (LTS)

## Uninstall old versions
sudo apt-get remove docker docker-engine docker.io containerd runc

## Update the apt package index and install packages to allow apt to use a repository over HTTPS:
sudo apt-get update
sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

## Add Docker’s official GPG key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

## Use the following command to set up the repository:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

## Update the apt package index:
sudo apt-get update

## Receiving a GPG error when running apt-get update?
sudo chmod a+r /etc/apt/keyrings/docker.gpg
sudo apt-get update

## Install Docker Engine, containerd, and Docker Compose:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
## Or Specific version, List the available versions:
apt-cache madison docker-ce | awk '{ print $3 }'
## Select the desired version and install:
VERSION_STRING=5:20.10.13~3-0~ubuntu-jammy
sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-compose-plugin

Binaries

Prerequisites

Before attempting to install Docker from binaries, be sure your host machine meets the prerequisites:

• A 64-bit installation
• Version 3.10 or higher of the Linux kernel. The latest version of the kernel available for your platform is recommended.
• iptables version 1.4 or higher
• git version 1.7 or higher
• A ps executable, usually provided by procps or a similar package.
• XZ Utils 4.9 or higher
• A properly mounted cgroupfs hierarchy; a single, all-encompassing cgroup mount point is not sufficient. See Github issues #2683, #3485, #4568).
