i遵循此步骤：https://minidcos.readthedocs.io/en/latest/dcos-vagrant-cli.html我用以下命令创建了一个集群：minidcos vagrant create ./dcos_generate_config.sh然后这个错误出现在我身上：以下SSH命令以非零退出状态响应。Vagrant认为这意味着命令失败！
yum install -y centos-release
命令的标准输出：
已加载的插件：fastestmirror
命令中的Stderr：

其中一个配置的存储库失败（Docker存储库），并且yum没有足够的缓存数据来继续。此时唯一yum可以做的安全的事情是失败。有几种方法可以“解决”此问题：
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=dockerrepo ...
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 dockerrepo
or
subscription-manager repos --disable=dockerrepo
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=dockerrepo.skip_if_unavailable=true
失败：来自dockerrepo的repodata / repomd.xml：[Errno 256]没有更多尝试使用的镜像。https://yum.dockerproject.org/repo/main/centos/7/repodata/repomd.xml：[Errno 14] HTTPS错误404-未找到
创建集群时出错。完整错误：命令'['/ usr / bin / vagrant'，'up']'返回非零退出状态1。
希望有人帮助我
如果有人坚持此错误，我找到了解决方案在Vagrantfile中：config.vbguest.auto_update = true将true替换为false
