Ubuntu用户

如果你过去安装过docker或docker-engine，先卸载：

$ sudo apt-get remove docker docker-engine docker.io containerd runc

然后安装依赖：

$ sudo apt-get update
$ sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

信任 Docker 的 GPG 公钥：

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

添加软件仓库：

$ 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

安装docker及docker-compose：

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose

CenOS/RHEL

如果你过去安装过docker或docker-engine，先卸载：

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

添加软件仓库：

$ sudo yum install -y yum-utils
$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

最后安装Docker：

$ sudo yum install docker-ce docker-ce-cli containerd.io docker-compose
