I don't see any problem here but don't know why it's not working.. Any help or guidance would be helpful
FYI, Today I was able to create keycloak pods successfully once but for retesting it I have deleted minikube and then recreated it. Afterward again I ran the same commands but not able to bring pods back as I am getting above mentioned errors.

Answer 1

Actually what happened is it shows Readiness Probe Failed but after some time Pod becomes ready automatically. Able to bring up the dashboard.
