Ssl 使用kubeadm设置Kubernetes群集，如何修复对等证书错误

我正在本地服务器（Centos 7.6）上使用kubeadm设置kubernetes群集。我得到了“对等证书错误”。我在

kubernetes.conf

中设置了

sslverify=0

，并且能够继续。但是，我想知道如何下载证书并在没有SSLVERFIY flase的情况下继续进行

[root@k8s-master yum.repos.d]# yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes
Loaded plugins: fastestmirror

Trying other mirror.
It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.
You can try to solve this issue by using the instructions on https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.



One of the configured repositories failed (Kubernetes),
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=kubernetes ...

 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 kubernetes
    or
        subscription-manager repos --disable=kubernetes

 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=kubernetes.skip_if_unavailable=true

failure: repodata/repomd.xml from kubernetes: [Errno 256] No more mirrors to try.
