centos8怎么安装原版的docker而不是podman

It looks like the yum-config-manager command is not found on your system. This could be because the yum-utils package, which provides this command, is not installed.

Here’s how you can install yum-utils and then add the Docker repository:

1. Install yum-utils:

   sudo yum install -y yum-utils
   

2. Add the Docker repository:

   sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
   

3. Install Docker Engine:

   sudo yum install -y docker-ce docker-ce-cli containerd.io
   

4. Start and enable Docker:

   sudo systemctl start docker
   sudo systemctl enable docker
   

5. Verify Docker installation:

   docker run hello-world
