API Group¶

so far, we were using kubectl utility. can also achieve same using REST api.
First, get master-node-address and port .
minikube ip
kubectl config view --minify -o jsonpath='{.clusters[0].cluster.server}'
API groups / categories --> all k8s resources are grouped under:
/metrics
/healthz
/version --> cluster version. ?
/api * --> core functionalities.
/apis * --> named. more organized. future functionalities.
/logs --> integrating with 3rd part logging server.
so, not all user can call all api. will authorize user, will give granular permission. check here
try:
curl http://localhost:6443 -k
curl https://master-node-address:6443/version
curl https://master-node-address:6443/api/v1/pods
fixes authentication issue:
- Fix-1 :: passing--> --key --cert --cacert
- fix-2 :: use kubectl proxy server.
- It forwards the request to kubeapi server with key,cacert,and cert.
- run on port 8001.
- curl http://localhost:8001/api
- Note: kube proxy and kubectl proxy, are different. check later.
