Kubernetes fails to run a docker image build locally

Question

I am trying to run a docker image that I have build locally with Kubernetes.

Here is my command line:

kubectl run myImage --image=myImage --port 3030 --image-pull-policy=IfNotPresent

I have seen many peoples saying that we need to add the --image-pull-policy=IfNotPresent flag so Kubernetes can look for the image locally instead of Docker Hub, but I still get this error (from the Minikube dashboard on the pod, the service and the deployment).

Failed to pull image "myImage": rpc error: code = Unknown desc = Error response from daemon: pull access denied for myImage, repository does not exist or may require 'docker login'

But it looks like there is another issue here, I also tried --image-pull-policy=Never and it doesn't work either.

Any idea?

Answer 1

The image is not available in minikube.

Minikube uses separate docker daemon. That's why, even though the image exists in your machine, it is still missing inside minikube.

First, send the image to minikube by,

docker save myImage | (eval $(minikube docker-env) && docker load)

This command will save the image as tar archive, then loads the image in minikube by itself.

Next, use the image in your deployment with image-pull-policy set to IfNotPresent

kubectl run myImage --image=myImage --port 3030 --image-pull-policy=IfNotPresent
