Access to kubernetes node via nsenter, similar with kubectl debug but more powerful

chmod +x ./kube-nodeshell.sh
# [optional] install kubectl plugin, make sure /usr/local/bin in your PATH
sudo mv ./kube-nodeshell.sh /usr/local/bin/kubectl-nodeshell

Usage

You can use the script kube-nodeshell.sh directly, or use kubectl plugin kubectl nodeshell

kubectl nodeshell {node_name}
