AuthN-AuthZ with Keycloak is not fully accessible via Kind Cluster environment locally

[hteeyeoh]

The authentication and authorization via JWT tokens generated by Keycloak using Kind Cluster is not working in local host.
Token fetching and curl command only able to work inside the kind container. This is because of the port exposing for kind cluster setup is much more complicated.
To make token fetching and curl command working in kind container, a w/a is needed:

1. set env proxy: HTTP_PROXY, HTTPS_PROXY, NO_PROXY
2. export KEYCLOAK_ADDR=<kind_container_ip>: <keycloak_node port>
3. export INGRESS_HOST=127.0.0.1
4. export INGRESS_PORT==
   $(kubectl -n "${INGRESS_NS}" get service "${INGRESS_NAME}" -o jsonpath='{.spec.ports[?(@.name=="http2")
   ].nodePort}'
5. Then perform token fetching and curl command in the container via "docker exec -it <kind_container_name> bash " command

This is for tracking purpose. As it is related to Kind Cluster infrastructure limitation not the Auth module here.
