Installing kubectl – CentOS

Iam getting a message as No package kubectl available while installing kubectl

I have followed the documentation mentioned here
for CentOS VERSION="7 (Core)" , Linux kernel version = 3.10.0-862.14.4.el7.x8

cat <<EOF > /etc/yum.repos.d/kubernetes.repo

     https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF
yum search kubectl
yum install -y kubectl

when it is executing the command yum search kubectl it is giving the following logs

I think it is not retrieving the key from “https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg“

    Ideally it should work with kubernetes.repo file also but it didn't work in my case. So installed using below steps from the official documentation and it was successful.

    curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.15.0/bin/linux/amd64/kubectl
chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl

    The package is clearly available from that repository, so we just need to check your configuration to make sure we can install it.

    <package pkgid="3d5dd3e6a783afcd660f9954dec3999efa7e498cac2c14d63725fafa1b264f14" name="kubectl" arch="x86_64"><version epoch="0" ver="1.15.0" rel="0"/><file>/usr/bin/kubectl</file></package>

    Source: https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64/repodata/filelists.xml

    I would first check that A)/etc/yum.repos.d/kubernetes.repo actually exists, and B) that the contents match, i.e., via cat /etc/yum.repos.d/kubernetes.repo.

    Next, both of the commands below can be used to search for the kubectl package.

    # Using search
yum search kubectl

# Using grep
yum list | grep kubectl

    For importing the GPG key for use with yum, see the following answer:

    1. Try with this:
    cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-$basearch
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

yum install -y kubelet kubeadm kubectl

    1. You may also try to install a specific version by executing: yum install -y kubelet-<version> kubectl-<version> kubeadm-<version>

    2. Always make sure your versions satisfy dependency requirements.

    3. If you have some older versions, uninstall them first.

    4. You may also consider using kubeadm init.

    Please let me know if that helped.
