Kubernetes REST API

Question

Does kubernetes accessible via a REST API? I was looking over at the Kubernetes API page and it all looks very cryptic / incomplete. They talk about new versions but have not disclosed the API usage or docs anywhere. I just wanted to know if there is a way to access the cluster information in any other way other than using the kubectl command.

Example usage:

What I do now:

kubectl get pod --context='my-prod-cluster'

What I'd like to do:

curl GET /some/parameters/to/get/info

Answer 1

您可以通过将--v=8传递给任何 kubectl 命令来查看 kubectl 正在进行的所有 API 调用

Answer 2

The REST API is fully documented on the Kubernetes website: https://kubernetes.io/docs/reference/using-api/api-overview/

It includes info on how to reach the API , be authorized to use the API , and a full breakdown of what API objects are available and what operations you can do on them.

Answer 3

The API is available to you outside of kubectl . In fact, my understanding is that underneath it all kubectl is just making REST calls to the API server. In a cluster using TLS certificates for authentication, a curl call to list your pods might look something like this (you can get your apiserver location/port with kubectl cluster-info | grep 'Kubernetes master' ):

curl --cert myuser.pem --key myuser-key.pem --cacert /path/to/ca.pem https://my-prod-cluster-apiserver:6443/api/v1/pods

This doc shows how to use kubectl proxy to allow you to explore the Swagger-generated API docs on your own cluster.

Answer 4

I think this is maybe what you find , though it is not always up to date. http://kubernetes.io/kubernetes/third_party/swagger-ui/

Answer 5

Kubernetes has an API reference page. It details all the operations accessible via the API. To access your cluster's API locally, make sure to proxy in, using kubectl proxy (after set-up of course).
