What is the meaning of ImagePullBackOff status on a Kubernetes pod?

Question

I\'m trying to run my first kubernetes pod locally. I\'ve run the following command (from here):

export ARCH=amd64
docker run -d \\
    --volume=/:/rootfs:ro \\
         


        

Answer 1

Despite all the other great answers none helped me until I found a comment that pointed out this Updating images:

The default pull policy is IfNotPresent which causes the kubelet to skip pulling an image if it already exists.

That's exactly what I wanted, but didn't seem to work.

Reading further said the following:

If you would like to always force a pull, you can do one of the following:

• omit the imagePullPolicy and use :latest as the tag for the image to use.

When I replaced latest with a version (that I had pushed to minikube's Docker daemon), it worked fine.

$ kubectl create deployment presto-coordinator \
    --image=warsaw-data-meetup/presto-coordinator:beta0
deployment.apps/presto-coordinator created

$ kubectl get deployments
NAME                 READY   UP-TO-DATE   AVAILABLE   AGE
presto-coordinator   1/1     1            1           3s

Find the pod of the deployment (using kubectl get pods) and use kubectl describe pod to find out more on the pod.
