Minikube Docker Local Registry

To use Minikube's built-in Docker registry, you can follow these steps:

1. Start Minikube:

   First, ensure Minikube is installed on your system. Then start Minikube with the following command:

minikube start

2. Enable Registry:

   Enable the registry addon in Minikube:

minikube addons enable registry

3. Configure Docker:

   Set your Docker environment to use Minikube's Docker daemon:

eval $(minikube docker-env)

4. Build Docker Image:

   Build your Docker image. For example:

docker build -t my-image:tag .

5. Tag the Image:

   Tag your Docker image with the Minikube registry:

docker tag my-image:tag localhost:5000/my-image:tag

6. Push Image to Registry:

   Push your Docker image to the Minikube registry:

docker push localhost:5000/my-image:tag

7. Pull Image form Registry: Pull your Docker image form minikube registry:

docker pull localhost:5000/my-image:tag

8. Port Forward the Registry Service:

   Forward the registry service to make it accessible on your local machine. Since the service is using ports 80 and 443, you can forward these ports to 5000 on your local machine.

kubectl port-forward -n kube-system service/registry 5000:80

This command forwards port 5000 on your local machine to port 80 on the registry service in Minikube.

9. Exit Minikube Docker Environment

eval $(minikube docker-env -u)

Use the Image in Kubernetes: You can now use your image in your Kubernetes manifests. Reference it as localhost:5000/my-image:tag.
