To use local Docker images with Minikube, you can follow these steps:

  1. Start the Minikube cluster by running the following command:

     
    minikube start

  2. Build the Docker image: Build the Docker image using the docker build command. For example, to build an image from a Dockerfile in the current directory, run the following command:

     
    docker build -t my-image .

    This will create a Docker image with the tag my-image.

  3. Load the image into Minikube: Load the Docker image into Minikube by running the following command:

     
    minikube image load my-image

    This will load the my-image Docker image into the Minikube Docker daemon.

  4. Use the image in a Kubernetes deployment: You can now use the my-image Docker image in a Kubernetes deployment by specifying the image name in the deployment manifest. For example:

     
    apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-container
        image: my-image
        ports:
        - containerPort: 8080

    This will create a deployment with one replica and a container named my-container, which uses the my-image Docker image.
