How to use local docker images with Minikube?
I have several docker images that I want to use with minikube
. I don't want to first have to upload and then download the same image instead of just using the local image directly. How do I do this?
Stuff I tried:
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 just gets stuck on some status but never reaches the ready state.
2. I tried creating a registry and then putting images into it but that didn't work either. I might've done that incorrectly but I can't find proper instructions to do this task.
Please provide instructions to use local docker images in local kubernetes instance.

If someone could help me get a solution that uses docker-compose to do this, that'd be awesome.

As the README describes, you can reuse the Docker daemon from Minikube with eval $(minikube docker-env)
.
So to use an image without uploading it, you can follow these steps:
- Set the environment variables with
eval $(minikube docker-env)
- Build the image with the Docker daemon of Minikube (eg
docker build -t my-image .
) - Set the image in the pod spec like the build tag (eg
my-image
) - Set the
imagePullPolicy
toNever
, 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.
What worked for me, based on the solution by @svenwltr:
# Start minikube
minikube start
# Set docker env
eval $(minikube docker-env) # unix shells
minikube docker-env | Invoke-Expression # PowerShell
# Build image
docker build -t foo:0.0.1 .
# Run in minikube
kubectl run hello-foo --image=foo:0.0.1 --image-pull-policy=Never
# Check that it's running
kubectl get pods
