Using Minikube with Local Docker Images

When developing locally with Minikube, you may want to use locally built Docker images instead of images hosted in a registry. Why push images up to Google’s GCR or AWS ECR if you’re only testing locally? Thankfully, this is simple with only a few steps.

  • With Minikube running, eval the docker-env to configure your shell to get started.
eval $(minikube docker-env)
  • Build your image.
  • In the containers specification of your deployment, use the locally built image and specify the imagePullPolicy. Setting this policy to IfNotPresent tells Kubernetes to use a local image preferentially.
    # This is for local use on minikube
    - image: nginx:20180919
      name: nginx
      imagePullPolicy: IfNotPresent
  • Apply the deployment and that’s it! You have a locally built image running in Minikube on your machine.
