What does minikube docker-env mean?

Question

In the Kubernetes minikube tutorial there is this command to use Minikube Docker daemon :

$ eval $(minikube docker-env)

What exactly does this

Answer 1

Try to run minikube docker-env

You will see some environment variables are mentioned there :)

These variables will help your docker CLI (where you write docker commands) to connect with docker daemon in the VM created by minikube !

---

Now, to connect your Docker CLI to the docker daemon inside the VM you need to run : eval $(minikube docker-env)

This will temporarily(for that terminal) connect CLI to docker daemon inside the VM :)

---

Now, try to do docker ps , you can see all the containers created inside the VM (will be shown only if you have done some work in k8's cluster)

This is all possible due to those environment variables by docker-env
