Docker安装

  1. 更换国内软件源，推荐 清华大学开源软件镜像源 。Ubuntu的软件配置文件是/etc/apt/sources.list, 将系统自带的文件做个备份，将该文件替换为下面内容，即可使用清华的软件源镜像。

    # 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse

  2. 如果你过去安装过docker，先删掉：

    1
    sudo apt-get remove docker docker-engine docker.io

  3. 首先安装依赖

    1
    2
    sudo apt-get install apt-transport-https ca-certificates \
       curl gnupg2 software-properties-common

  4. 信任Docker的GPG公钥

    1
    curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

  5. 添加清华的软件仓库

    1

    4
    sudo add-apt-repository \
       "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

  6. 安装

    1
    2
    sudo apt-get update
    sudo apt-get install docker-ce

Docker一些设置

  1. 设置开机启动。(安装后默认设置开机启动，可忽略)

    1
    2
    sudo systemctl enable docker
    sudo systemctl start docker

  2. 添加当前用户到docker用户组，可以不用 sudo 运行docker

    1
    2
    sudo groupadd docker
    sudo usermod -aG docker $USER
