Not able to access keycloak on kubernetes

I am facing a weird issue, my keycloak is running successfully in minikube but at the same time I am not able to access by port forwarding to 8080. I wanted my own spi to be deployed so created a new docker image file as shown below.

FROM jboss/keycloak:latest
ADD common-keycloak-spi-0.1.jar /opt/jboss/keycloak/standalone/deployments/
ENTRYPOINT ["/usr/bin/env"]
CMD ["sh","/opt/jboss/tools/docker-entrypoint.sh"]

Now this runs fine in docker container but when I am trying to depoloy it on kubernetes I am unable to access the service by using port forwading.

vipul@vipul-Latitude-5530:~/Downloads$ kubectl port-forward springdoc-64f8dbf547-xrqcl 8080:8080

And also getting NONE for any port and host port in kubectl describe <POD>.

Thanks

You can check the following step to troubleshoot the issue:

1. Check whether the firewall is blocking the port. “netstat -anp | grep 8080”

2. Check the pod is configured correctly with port and host port in the config yaml file. Use thislink as a reference.

3. If you are using the same port configuration in Docker container and in the kubectl will not access the same port so try to check the port number.

Also you can check the blog by Ales Nosek for hostport.
