v1.12.1: The minikube docker container exited unexpectedly.

[etanshaul]

Minikube 1.12.1, on OSX using the docker driver
Using Cloud Run workflows from the IDE.

What happened

• I was successfully running through the Cloud Run local workflows from Cloud Code: Minikube was paused, I'd start the dev session, and Minikube would successfully unpause and things worked great
• I then wanted to test out things from scratch, so I issued on the command line against my Cloud Code managed minikube binary: minikube delete --all --purge.
• I reran the session and got the output shown at the bottom (full verbose output: https://paste.googleplex.com/6439869599449088)

What I tried

• I tried running docker system prune -a, same error

Docker Desktop Setup

• 2 CPUs
• 8GB memory

* If you are still interested to make docker driver work. The following suggestions might help you get passed this issue:
* 
	- Prune unused docker images, volumes and abandoned containers.
* 
	- Restart your docker service
* 
	- Ensure your docker daemon has access to enough CPU/memory resources. 
* 
	- Docs https://docs.docker.com/docker-for-mac/#resources
* 
	- Delete and recreate minikube cluster
		minikube delete
		minikube start --driver=docker

thanks @medyagh . Assuming I say in this state with minikube 1.12.1, I assume that on upgrade once the new minikube version is released it will transition smoothly into a working state?
