centos8 安装docker

1 卸载老版本的docker容器 不是root用户使用sudo为开头

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

2 更新软件

sudo yum -y update

3 设置存储库

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

   sudo yum install docker-ce docker-ce-cli

5 启动docker容器

sudo systemctl start docker

6 替换docker源 阿里云搜索 镜像加速器 下面的是我的配置

https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors

sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://v8cenbom.mirror.aliyuncs.com"]
