Obtain Kubernetes API key with Java

I'm using k8s java client and need a way to get OAuth access token for some clusters. Now I can do that only with this bash script:

export KUBECONFIG=~/.kube/<config-file>

APISERVER=$(kubectl config view --minify | grep server | cut -f 2- -d ":" | tr -d " ")
SECRET_NAME=$(kubectl get secrets | grep ^default | cut -f1 -d ' ')
TOKEN=$(kubectl describe secret $SECRET_NAME | grep -E '^token' | cut -f2 -d':' | tr -d " ")

echo "TOKEN: ${TOKEN}"

Is there a way to do that with java code? Don't ask for the whole solution but at least for some direction to look.

The Kubernetes config is stored as a YAML file. Use a library to read and parse it, example

In the end you'll get an object with all the keys and values from the config. Just access directly what you need.

Kubernetes is not involved in the OAuth side of things at all. That’s up to your IdP. More normally you would use a ServiceAccount token for automation though.
