I am newbie in Go. I want to get the storage statistics of nodes and cluster in kubernetes using Go code. How i can get the free and used storage of Kubernetes nodes and cluster using Go.
This is actually 2 problems:
How do I perform http requests to the kubernets master?
See [1] for more details. Tl;dr you can access the apiserver in at least 3 ways:
a. kubectl get nodes (not go)
b. kubectl proxy, followed by a go http client to this url
c. Running a pod in a kubernetes cluster
What are the requests I need to do to get node stats?
a. Run kubectl describe node, it should show you resource information.
b. Now run kubectl describe node --v=7, it should show you the REST calls.
I also think you should reformat the title of your question per https://stackoverflow.com/help/how-to-ask, so it reflects what you're really asking.
