Are there any locations where I can see all pod's configuration scheduled on that workernode?

I would like to run some static checks on each worker nodes using Ansible to check if the pod's have been given enough resources (CPU/MEM), I have to explicitly run this job on worker node only and not through kubectl API call.

Thanks!

You can try below command

crictl stats

if you are using docker as runtime then replace crictl with docker

CodePudding user response：

This command can be executed from any node or from a system which has access to the cluster. It gives the pods in all namespaces deployed in a particular node.

kubectl get pods -A -o wide --field-selector spec.nodeName=<nodename>

This will list all pods from all namespaces but you can narrow it down for specific namespace by the following command.

kubectl get pods -n ns -o wide --field-selector spec.nodeName=<nodename>

Replace ns with required namespace.

For requests and limits

kubectl describe nodes <node name>

kubectl get pods -o yaml 

you can see the pods running on the node and their cpu and memory requests and limits.
