failure: repodata/repomd.xml from kubernetes: [Errno 256] No more mirrors to try. [Errno -1] repomd.xml signature could not be verified for kubernetes

 Issue: 

when installing kubernetes I got massage like this :

Trying other mirror.

 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

Solution :

the solution is simpel 

jus make your  /etc/yum.repos.d/kubernetes.repo file change repo_gpgcheck part to  0 

like this 

[kubernetes]

name=Kubernetes

baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64

enabled=1

gpgcheck=1

repo_gpgcheck=0

gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg

now continue your tutorial articel to install kubernetes

hope it help sorry for bad english
