解决方式：

列出并排序您存储库中可用的版本。此示例按版本号（从高到低）对结果进行排序。

呵呵，又是新问题。。。。。

看上面的内容，说的是containerd.io >= 1.2.2-3 ，意思就是 containerd.io 的版本必须大于等于 1.2.2-3

要么就降低docker 的版本，要么就更新 containerd.io 的版本。

到https://download.docker.com/linux/centos/7/x86_64/edge/Packages/ 这里去看看最新版本的dontainerd.io

我这儿选最新的一个版本下载。

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

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集
