安装docker

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils

# Step 2: 添加软件源信息
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# Step 3: 安装Docker
sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Step 4: 开启Docker服务
sudo systemctl start docker
systemctl enable docker

# 注意：
# 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。
# vim /etc/yum.repos.d/docker-ce.repo
#   将[docker-ce-test]下方的enabled=0修改为enabled=1
#
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
#   Loading mirror speeds from cached hostfile
#   Loaded plugins: branch, fastestmirror, langpacks
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            docker-ce-stable
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            @docker-ce-stable
#   docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable
#   Available Packages
# Step2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.1-1.el7.centos)
# sudo yum -y install docker-ce-[VERSION]
