Using local docker images with Minikube

0 votes

I've got a few custom docker images I want to use directly with minikube instead of uploading them and tehn using them. So this is what I've tried so far:

1. I tried running these commands (separately, deleting the instances of minikube both times and starting fresh)

kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989
kubectl run hdfs --image=fluxcapacitor/hdfs:latest --port=8989 imagePullPolicy=Never

Output :

NAME                    READY     STATUS              RESTARTS   AGE
hdfs-2425930030-q0sdl   0/1       ContainerCreating   0          10m

It never gets ready.

2. I also tried using the registry by uploading the images to it but for some reason that too isn't working.

Please provide instructions to use local docker images in local kubernetes instance.

Please help I don't know where to go from here, thanks.

You can reuse the Docker daemon from minikube with eval minikube docker-env). Do this to use your local images with minikube without uploading them

  1. set the environment variables with eval $(minikube docker-env)
  2. build the image with the Docker daemon of Minukube (eg docker build -t my-image .)
  3. set the image in the pod spec like the build tag (eg my-image)
  4. set the imagePullPolicy to Never, otherwise Kubernetes will try to download the image.

Important note: You have to run eval $(minikube docker-env) on each terminal you want to use, since it only sets the environment variables for the current shell session.
