This was solved. There is a mistake in the docs.

I can see there is a mistake in the docs.

Line containing exclude=kube* should be removed.

It should be as follows:

cat <<EOF > /etc/yum.repos.d/kubernetes.repo [kubernetes] name=Kubernetes baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64 enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg EOF setenforce 0 yum install -y kubelet kubeadm kubectl systemctl enable kubelet && systemctl start kubelet

yum remove kubernetes-client 
yum remove kubernetes-node
yum clean packages
yum update
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet && systemctl start kubelet

The exclude=kube* will actually exclude all pkgs. Just remove it and it should work.

For me, this issue was solved by following the instructions more closely:

yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

the flag there at the end makes this work.

Hi

It sounds like packages not found by yum repo commands. Do try yum repo clean & yum update & then try installing the packages.

There is no such thing as “yum repo clean”, maybe you meant “yum clean all”?

Still error for me on CentOS 7.5 , worked after removed line: exclude=kubelet kubeadm kubectl and systemctl enable kubelet && systemctl start kubelet
