1.Docker安装
1.1 删除旧的Docker版本（待验证，在新创建的虚拟机里安装的，没有这步操作）
[root@bogon ~]# sudo dnf remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
[root@bogon ~]# sudo yum remove docker*
1.2 使用安装脚本自动安装
官方安装脚本
[root@bogon ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
国内 daocloud 一键安装命令（待验证，官方脚本可正常使用，，可跳过）
[root@bogon ~]# curl -sSL https://get.daocloud.io/docker | sh
1.2.1 官方安装脚本记录
[root@bogon ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

================================================================================
To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:
dockerd-rootless-setuptool.sh install
Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.
To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/
WARNING: Access to the remote API on a privileged Docker daemon is equivalent
to root access on the host. Refer to the 'Docker daemon attack surface'
documentation for details: https://docs.docker.com/go/attack-surface/

1.3 使用yum安装（待验证，使用官方安装脚本安装的，可跳过）
1.3.1、设置Docker yum源
[root@bogon ~]# sudo yum install -y yum-utils
[root@bogon ~]# sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
1.3.2 安装最新的Docker engine
sudo yum install docker-ce docker-ce-cli containerd.io
1.3.2.1 安装指定版本Docker engine
#找到所有可用docker版本列表
yum list docker-ce --showduplicates | sort -r
# 安装指定版本，用上面的版本号替换<VERSION_STRING>
sudo yum install docker-ce-<VERSION_STRING>.x86_64 docker-ce-cli-
<VERSION_STRING>.x86_64 containerd.io
#例如：
#yum install docker-ce-3:20.10.5-3.el7.x86_64 docker-ce-cli-3:20.10.5-
3.el7.x86_64 containerd.io
#注意加上 .x86_64 大版本号
1.4 docker启动服务
systemctl start docker
systemctl enable docker
1.5 镜像加速
- 科大镜像：docker.mirrors.ustc.edu.cn/
- 网易：hub-mirror.c.163.com/
- 阿里云：https://<你的ID>.mirror.aliyuncs.com
- 七牛云加速器：reg-mirror.qiniu.com
以阿里云为例：
官方镜像加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://bbq6yc2w.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
