kubernetes go client used storage of nodes and cluster

问题

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.

回答1:

This is actually 2 problems:

1. 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

2. 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.
