When kubelet is installed, run the command:
yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes
The following prompts and errors appear:
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:
-
Contact the upstream for the repository and get them to fix the problem.
-
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). -
Run the command with the repository temporarily disabled
yum --disablerepo=kubernetes … -
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 -
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.

Two solutions: The main reason for this problem is that there is a problem with Ali's domestic yum source. It should be that the file path has been changed or upgraded, or the original file does not exist; prompts provide 1-5 solutions.
At this time, only It is necessary to modify the gpgcheck and repo_gpgcheck parameters of /etc/yum.repos.d/kubernetes.repo, and change it to 0, see below:
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
exclude=kubelet kubeadm kubectl
EOF
In this way, run yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes again
to install kubelet.
