Troubleshooting Services

We will see how to root cause failures for services.

Try to list the service, and see the service type. Then make a call to the service (using an ephemeral pod).

There is a command get endpoints. It will render all the virtual ip of pods a service should be able to route.

If we see <none> we have issues with connecting the pod.

2 sources of misconfiguration:

• label selector,
• targetport does not match with the container port.

Check the network policies. k get networkpolicies, make sure it says none

Make sure the pods are running.
