安装依赖

sudo yum install -y yum-utils  device-mapper-persistent-data  lvm2
    sudo yum-config-manager  --add-repo   https://download.docker.com/linux/centos/docker-ce.repo
    sudo yum install docker-ce docker-ce-cli containerd.io

安装containerd.io出现错误如下

方法一  
1、查看是否安装 Podman

[root@localhost yum.repos.d]# rpm -q podman
    podman-2.0.5-5.module_el8.3.0+512+b3b58dca.x86_64

2、删除之后在重新yum install docker-ce下载

[root@localhost yum.repos.d]# dnf remove podman

方法二

yum erase podman buildah

然后一路y 完事在下载yum install docker-ce

再装剩下两个

sudo yum install docker-ce docker-ce-cli
    sudo systemctl start docker
    docker --version

开机自启

sudo systemctl enable docker

接着，我们可以使用Docker进行容器的创建：

docker info                # 查看docker的信息
    docker search img_name     # 搜索名为img_name的镜像
    docker pull img_name       # 将名为img_name的镜像下载到本地
    docker images              # 查看本地已有的镜像
    docker rmi img_name        # 删除名为img_name的镜像
     
    docker ps                  # 列出正在运行的容器
    docker ps -a               # 列出所有的容器
    docker run -itd --name=container_name img_name  # 使用img_name以交互模式在后台运行分配了伪终端的名为container_name的镜像
     
    docker start container_name/container_id        # 通过容器名字或ID启动容器
    docker stop container_name/container_id         # 通过容器名字或ID停止容器
    docker restart container_name/container_id      # 通过容器名字或ID重启容器
    docker rm container_name/container_id           # 通过容器名字或ID删除容器
     
    docker exec -it container_name/container_id /bin/bash   # 通过容器名字或ID进入容器
    exit
