#0 24.86 One of the configured repositories failed (Unknown),
#0 24.86 and yum doesn't have enough cached data to continue. At this point the only
#0 24.86 safe thing yum can do is fail. There are a few ways to work "fix" this:
#0 24.86
#0 24.86 1. Contact the upstream for the repository and get them to fix the problem.
#0 24.86
#0 24.86 2. Reconfigure the baseurl/etc. for the repository, to point to a working
#0 24.86 upstream. This is most often useful if you are using a newer
#0 24.86 distribution release than is supported by the repository (and the
#0 24.86 packages for the previous distribution release still work).
#0 24.86
#0 24.86 3. Run the command with the repository temporarily disabled
#0 24.86 yum --disablerepo=<repoid> ...
#0 24.86
#0 24.86 4. Disable the repository permanently, so yum won't use it by default. Yum
#0 24.86 will then just ignore the repository until you permanently enable it
#0 24.86 again or use --enablerepo for temporary usage:
#0 24.86
#0 24.86 yum-config-manager --disable <repoid>
#0 24.86 or
#0 24.86 subscription-manager repos --disable=<repoid>
#0 24.86
#0 24.86 5. Configure the failing repository to be skipped, if it is unavailable.
#0 24.86 Note that yum will try to contact the repo. when it runs most commands,
#0 24.86 so will have to try and fail each time (and thus. yum will be be much
#0 24.86 slower). If it is a very temporary problem though, this is often a nice
#0 24.86 compromise:
#0 24.86
#0 24.86 yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
#0 24.86
#0 24.86 Cannot find a valid baseurl for repo: base/7/x86_64

ERROR: failed to solve: process "/bin/sh -c yum -y install vim net-tools wget" did not complete successfully: exit code: 1
尝试过更换yum源、检查网络等等，均无法解决。
最后将docker 重启了，但是生产环境需要谨慎重启docker
systemctl restart docker再次执行
