(使用中科大鏡像源，同時支持PC與ARM設備)

1.添加源文件/etc/apt/sources.list.d/ustc.list

(也可以直接修改原來的/etc/apt/sources.list)

deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-backports main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-proposed main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-security main multiverse restricted universe
deb http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates main multiverse restricted universe
#deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe
#deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-backports main multiverse restricted universe
#deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-proposed main multiverse restricted universe
#deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-security main multiverse restricted universe
#deb-src http://mirrors.ustc.edu.cn/ubuntu-ports/ bionic-updates main multiverse restricted universe

2.安裝必要工具

sudo apt-get update\
sudo apt-get -y install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

3.添加軟件源的 GPG 密鑰

curl -fsSL https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

4.向 source.list 中添加 Docker 軟件源

sudo add-apt-repository \
    "deb https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu \
    $(lsb_release -cs) \
    stable"

5.更新緩存并安裝docker

sudo apt-get update
sudo apt-get -y install docker-ce

6.創建用戶組并添加當前用戶

sudo groupadd docker
sudo usermod -aG docker $USER
