I am trying to write a .net core application to run in a kubernetes pod. This application needs to know if the cluster has been unable to schedule any pods.
I have tried getting deployment data from
kubectl get --raw /apis/apps/v1/namespaces/default/deployments
I can see the
unavailableReplicas number and the
Are these valid metrics to watch for the cluster status?
Is there a way to query the cluster as a whole instead of by deployment?
If you are looking for the images in each node in the cluster you can try
kubectl get nodes -o json
which will return a json object or using --field-selector as shown below.
kubectl get pods --all-namespaces --field-selector=status.phase==Pending
and using api
kubectl get --raw /api/v1/pods?fieldSelector=status.phase==Pending
