I created a docker image of my app which is running an internal server exposed at 8080. Then I tried to create a local kubernetes cluster for testing, using the following set of commands.
$ kubectl create deployment --image=test-image test-app
$ kubectl set env deployment/test-app DOMAIN=cluster
$ kubectl expose deployment test-app --port=8080 --name=test-service
I am using Docker-desktop on windows to run run kubernetes. This exposes my cluster to external IP localhost but i cannot access my app. I checked the status of the pods and noticed this issue:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
test-66-ps2 0/1 ImagePullBackOff 0 8h
test-6f-6jh 0/1 InvalidImageName 0 7h42m
May I know what could be causing this issue? And how can i make it work on local ? Thanks, Look forward to the suggestions!
