Kubenpod is a tool designed to simplify listing and monitoring pods operating on a specific node within a Kubernetes cluster. You can utilize it by specifying a node name or a pod name, as demonstrated in the examples below. If you encounter any issues or have suggestions, feel free to leave a comment.
To install Kubenpod, execute the following commands in your terminal:
sudo curl -LO https://raw.githubusercontent.com/ehok/toppod/master/kubenpod > kubenpod
sudo chmod +x kubenpod
sudo mv kubenpod /usr/local/bin/kubenpod
After installation, you can use the following commands:
$ kubenpod --help
USAGE:
kubenpod <NODE_NAME> : show metrics of all pods of the <NODE_NAME>
kubenpod -p <POD_NAME> : show metrics of pods of the <POD_NAME>'s node
kubenpod : show this message
kubenpod -h,--help : show this message
kubenpod -l,--list <NODE_NAME> : list all pods of the <NODE_NAME>
kubenpod -lp,--listpod <POD_NAME> : list all pods of the <POD_NAME>'s node
To display metrics for all pods on a specific node:
$ kubenpod ip-10-0-0-1.us-east-1.compute.internal
hoke hoke-deployment-cda628x58-p1vzz 176m 267Mi
kube-system aws-node-r6n1m 3m 28Mi
kube-system coredns-165c7a19dd-st08z 3m 20Mi
kube-system kube-proxy-ty1m6 1m 14Mi
kube-system spot-interrupt-handler-f7syd 2m 4Mi
monitoring prometheus-node-exporter-d91th 2m 9Mi
nginx-ingress nginx-ingress-controller-vqf8q 36m 151Mi
To show metrics of the node where a specific pod is running:
$ kubenpod -p hoke-deployment-cda628x58-p1vzz
hoke hoke-deployment-cda628x58-p1vzz 176m 267Mi
kube-system aws-node-r6n1m 3m 28Mi
kube-system coredns-165c7a19dd-st08z 3m 20Mi
kube-system kube-proxy-ty1m6 1m 14Mi
kube-system spot-interrupt-handler-f7syd 2m 4Mi
monitoring prometheus-node-exporter-d91th 2m 9Mi
nginx-ingress nginx-ingress-controller-vqf8q 36m 151Mi
To list all pods on a specific node:
$ kubenpod -l ip-10-0-0-1.us-east-1.compute.internal

To list all pods on the node where a specific pod is running:
$ kubenpod -lp hoke-deployment-cda628x58-p1vzz
