Explore the Kubernetes API¶
Outcomes¶
- Understand the Kubernetes API
- Query the Kubernetes API using kubectl and curl
Outline¶
Increase verbosity of kubectl output
kubectl get pods -v=8
Notice the curl
command at the top of the output; save it as you'll need it later.
Create a service account and cluster role binding
kubectl create serviceaccount k8s-api-explorer
kubectl create clusterrolebinding k8s-api-explorer --clusterrole=cluster-admin --serviceaccount=default:k8s-api-explorer
Get the token for the service account
TOKEN=$(kubectl create token k8s-api-explorer -o jsonpath='{.data.token}')
Now construct the curl command to query the API
curl -k -v -XGET -H "Authorization: Bearer ${TOKEN}" <URL from command above>
