docker build 没有网络 执行dockerfile中yum报错 curl#6 - “Could not resolve host: mirrorlist.centos.org 解决方法_curl#6 - "could not resolve host: mirrorlist.cento

curl#6 - "could not resolve host: mirrorlist.centos.org; unknown error

报错现象

  1. Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
  2. 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
  3. One of the configured repositories failed (Unknown),
  4. and yum doesn't have enough cached data to continue. At this point the only
  5. safe thing yum can do is fail. There are a few ways to work "fix" this:
  6. 1. Contact the upstream for the repository and get them to fix the problem.
  7. 2. Reconfigure the baseurl/etc. for the repository, to point to a working
  8. upstream. This is most often useful if you are using a newer
  9. distribution release than is supported by the repository (and the
  10. packages for the previous distribution release still work).
  11. 3. Run the command with the repository temporarily disabled
  12. yum --disablerepo=<repoid> ...
  13. 4. Disable the repository permanently, so yum won't use it by default. Yum
  14. will then just ignore the repository until you permanently enable it
  15. again or use --enablerepo for temporary usage:
  16. yum-config-manager --disable <repoid>
  17. or
  18. subscription-manager repos --disable=<repoid>
  19. 5. Configure the failing repository to be skipped, if it is unavailable.
  20. Note that yum will try to contact the repo. when it runs most commands,
  21. so will have to try and fail each time (and thus. yum will be be much
  22. slower). If it is a very temporary problem though, this is often a nice
  23. compromise:
  24. yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
  25. 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
