Description

I noticed that preloaded-images-k8s and index.docker.io/kicbase progress bars step on each other when download is in progress and it is confusing for the user and might be interpreted as a glitch. When the download is finished, they are displayed in separate lines:

minikube start --driver=docker
😄  minikube v1.19.0 on Darwin 10.15.7
✨  Using the docker driver based on user configuration
👍  Starting control plane node minikube in cluster minikube
