### 报错现象 ###

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
    14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
    
    
     One of the configured repositories failed (Unknown),
     and yum doesn't have enough cached data to continue. At this point the only
     safe thing yum can do is fail. There are a few ways to work "fix" this:
    
         1. Contact the upstream for the repository and get them to fix the problem.
    
         2. Reconfigure the baseurl/etc. for the repository, to point to a working
            upstream. This is most often useful if you are using a newer
            distribution release than is supported by the repository (and the
            packages for the previous distribution release still work).
    
         3. Run the command with the repository temporarily disabled
                yum --disablerepo=<repoid> ...
    
         4. Disable the repository permanently, so yum won't use it by default. Yum
            will then just ignore the repository until you permanently enable it
            again or use --enablerepo for temporary usage:
    
                yum-config-manager --disable <repoid>
            or
                subscription-manager repos --disable=<repoid>
    
         5. Configure the failing repository to be skipped, if it is unavailable.
            Note that yum will try to contact the repo. when it runs most commands,
            so will have to try and fail each time (and thus. yum will be be much
            slower). If it is a very temporary problem though, this is often a nice
            compromise:
    
                yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
    
    Cannot find a valid baseurl for repo: base/7/x86_64

### 部署情况 ###

win10安装VMware， VMware中安装了centos7 在centos7上进行 docker build

### 可能原因 ###

1.centos7宿主机和docker网络问题

2.win10中的VMware 造成的centos7虚拟机 中的docker网络问题

### 解决方法 ###

方法1：重启docker 命令为：systemctl restart docker

方法2：重启VMware宿主机 win10系统
