Docker for Windows Kubernetes pod gets ImagePullBackOff after creating a new deployment

I just had the exact same problem. Boils down to the imagePullPolicy:

PC:~$ kubectl explain deployment.spec.template.spec.containers.imagePullPolicyKIND:     DeploymentVERSION:  extensions/v1beta1FIELD:    imagePullPolicy <string>DESCRIPTION:     Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always     if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated.     More info:     https://kubernetes.io/docs/concepts/containers/images#updating-images

Specifically, the part that says: Defaults to Always if :latest tag is specified.

That means, you created a local image, but, because you use the :latest it will try to find it in whatever remote repository you configured (by default docker hub) rather than using your local. Simply change your command to:

kubectl run myapp --image=myimage:latest --image-pull-policy Never

or

kubectl run myapp --image=myimage:latest --image-pull-policy IfNotPresent

You didn't specify where myimage:latest is hosted, but essentially ImagePullBackoff means that I cannot pull the image because either:

• You don't have networking setup in your Docker VM that can get to your Docker registry (Docker Hub?)
• myimage:latest doesn't exist in your registry or is misspelled.
• myimage:latest requires credentials (you are pulling from a private registry). You can take a look at this to configure container credentials in a Pod.

I had this same ImagePullBack error while running a pod deployment with a YAML file, also on Docker Desktop.

For anyone else that finds this via Google (like I did), the imagePullPolicy that Lucas mentions above can also be set in the deployment yaml file. See the spec.templage.spec.containers.imagePullPolicy in the yaml snippet below (3 lines from the bottom).

I added that and my app deployed successfully into my local kube cluser, using the kubectl yaml deploy command: kubectl apply -f .\Deployment.yaml
