I tried to deploy kubernetes using minikube using both from local docker image and from docker hub. But both doesn't work.

method-1: Using save and load the tar file, created the image and it is available to kubectl.

root@arun-desktop-e470:/var/local/dprojects/elasticsearch# kubectl get pods --all-namespaces -o jsonpath="{..image}" |tr -s '[[:space:]]' '\n' |sort |uniq -c|grep elk
      2 elk/elasticsearch:latest

Execute below commands to create the deployment:

kubectl run elastic --image=elk/elasticsearch:latest --port=9200
kubectl expose deployment elastic --target-port=9200 --type=NodePort
minikube service elastic --url

From kubectl describe pod command,

  Warning  Failed     122m (x4 over 124m)   kubelet, minikube  Failed to pull image "elk/elasticsearch:latest": rpc error: code = Unknown desc = Error response from daemon: pull access denied for elk/elasticsearch, repository does not exist or may require 'docker login'

Method-2: I did pushed the image to my docker hub repository, (https://hub.docker.com/r/get2arun/elk/tags) and then login to docker hub in the terminal and created the deployment again.

pushed to docker hub like below and hence I have permission to push and pull the images to my docker hub account. I have checked the "collaborators" under manage repositories and it has my docker hub id.

root@arun-desktop-e470:~# docker push get2arun/elk:elasticsearch_v1
The push refers to repository [docker.io/get2arun/elk]

kubectl run elasticsearch-v2 --image=get2arun/elk:elasticsearch_v1 --port=9200

From kubectl describe pods command:

I removed the proxy settings and tried from open wifi account but still seeing permission denied.

This error message is not sufficient to identify the issue and hoping there should be some way to narrow down these kind of issues.

1. What happens in the background when Kubernetes is asked to use the local docker image or pull the image from docker hub?
2. How to get all the log information when deployment is started ?
3. What are the other sources for logs
