前言

docker相关的网站已经给墙了，所以安装起来就比较麻烦，这里做一个安装记录。

安装过程

1. 准备条件

#安装前先卸载操作系统默认安装的docker，
sudo apt-get remove docker docker-engine docker.io containerd runc

#安装必要支持
sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

2. 安装

#添加 Docker 官方 GPG key （可能国内现在访问会存在问题）
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

# 阿里源（推荐使用阿里的gpg KEY）
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg



#添加 apt 源:
#Docker官方源
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null


#阿里apt源
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null


#更新源
sudo apt update
sudo apt-get update

安装Docker
#安装最新版本的Docker
sudo apt install docker-ce docker-ce-cli containerd.io
#等待安装完成

#查看Docker版本
sudo docker version

#查看Docker运行状态
sudo systemctl status docker

3. 安装Docker 命令补全工具(可无)

sudo apt-get install bash-completion

sudo curl -L https://raw.githubusercontent.com/docker/docker-ce/master/components/cli/contrib/completion/bash/docker -o /etc/bash_completion.d/docker.sh

source /etc/bash_completion.d/docker.sh

4. 开机启动

# 启动& 开机启动docker； enable + start 二合一
systemctl enable docker --now

5. 配置hub加速

# 配置加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "registry-mirrors": [
        "https://mirror.ccs.tencentyun.com",
        "https://docker.m.daocloud.io"
    ]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
