I created pods using objects in kubernetes but the pods have status "Pending"
I created pods using kubectl create -f file.yaml. Deployment successfully gets created but the status of the pods show Pending. I also have docker image available on my local repository for which I am creating the pod. I am not sure what the issue is.
The yaml file is as follows.
Kubernetes version that I am running is 1.1.6.

Just from that information I cannot deduce what is wrong. What I can write is how to help you address such issues. kubectl describe pod __name_of_your_pod__ kubectl describe delpoyment nginx_deployment What I think has happend you might have no cpu resources, no nodes or taints.
BTW 1.1.6 k8s is pretty old. Think about an upgrade.
You should be able to get more info from the pod logs. For example ...
kubectl logs --tail=100 nginx-deploymentMore information in the kubectl docs
Alternatively, you can open a console session, and troubleshoot from within the container itself.
kubectl get pods # To get actual pod name
kubectl exec -it <POD_NAME>
Another thing you can try is running your container outside of Kubernetes(using docker run -p 80:80 nginx-deployment) just to ensure that your app is running correctly, and responding etc.
You can also try running kubectl describe nodes. This might give you more info to troubleshoot with.
Run the following command to get the pods
kubectl get pods --all-namespacesto find more info, run:
kubectl describe po <you-pod-name>you should be able to get more info from that output. Mostly 1) image is still pulled 2) resources crunch or docker not running
but the error/info message should take you forward.
