CentOS7.9安装docker
1、将系统包更新到最新
1、配置epel源
[root@jintest ~]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

2、更新系统安装包到最新
-
yum update 升级系统安装包
-
升级完成后关机做快照，然后开机
2、安装docker
1、 获取docker镜像源
[root@jintest ~]# wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

3、启动docker
-
systemctl start docker #启动docker -
docker version #查看docker版本
[root@jintest ~]# systemctl start docker
[root@jintest ~]# docker version

注：离线安装
离线安装需要下载至少如下4个rpm包，传到服务器上，再去安装，安装过程中可能还需要解决依赖
docker -ce
containerd.io
docker-ce-cli
container-selinux
3、配置docker镜像加速
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://rqybk619.mirror.aliyuncs.com"]
}
EOF
systemctl daemon-reload
systemctl restart docker
4、运行一个docker镜像
[root@jintest ~]# docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
