这是下载源没有找到对应的安装包，更换下载源即可，如下操作：
文章地址：https://blog.csdn.net/qq_58159763/article/details/143830116
 直接到阿里巴巴开源镜像站下载Centos-7.repo yum源
 wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
更换yum源后记得执行：yum clean all && yum repolist
再次执行yum install docker-ce docker-ce-cli containerd.io 即可。

 
# 或方式二：选择安装指定版本 例如docker-ce-24.0.9
yum install docker-ce- docker-ce-cli- containerd.io
 
# 若选择测试版本的 Docker 请执行以下命令
yum-config-manager --enable docker-ce-test

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
 
Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/

若能正常输出以上信息，则说明安装成功。
