Local Images

Running local Docker images in Minikube requires loading them into Minikube's Docker.

Read more on "Pushing directly to the in-cluster Docker Daemon".

Reuse the Docker daemon from Minikube

Use the docker-env output to setup the Docker environment from Minikube as primary Docker.

eval $(minikube docker-env)

Load an Image into Minikube

You must build the image before, run: docker build -t local/bun-hello-world .

To make an image available for Minikube, the image must be loaded first.

minikube image load local/bun-hello-world

Create a Pod with Local Image

Create a Pod with the image on Kubernetes could be done by creating the following pod.yaml, then applying it with kubectl apply -f pod.yaml.

apiVersion: v1
kind: Pod
metadata:
  name: bun-hello-world
  labels:
    app: bun-hello-world
    tier: backend
spec:
  containers:
    - name: bun-hello-world
      image: local/bun-hello-world
      imagePullPolicy: Never

The imagePullPolicy is used to restrict Kubernetes from pulling the image from the registry and to instead use the local image.

Check the Pod is running:

kubectl get pod

NAME              READY   STATUS    RESTARTS   AGE
bun-hello-world   1/1     Running   0          19s

Port-Forward Pod

To access the Pod, you must run the kubectl port-forward command.

kubectl port-forward bun-hello-world 3030:3030
