Trying with driver=docker
[dave@dave simple-k8s]$ minikube start --driver=docker
😄 minikube v1.14.2 on Fedora 32
❗ Both driver=docker and vm-driver=kvm2 have been set.
Since vm-driver is deprecated, minikube will default to driver=docker.
If vm-driver is set in the global config, please run "minikube config unset vm-driver" to resolve this warning.
✨ Using the docker driver based on user configuration
👍 Starting control plane node minikube in cluster minikube
🚜 Pulling base image ...
🔥 Creating docker container (CPUs=2, Memory=3900MB) ...
🧯 Docker is nearly out of disk space, which may cause deployments to fail! (94% of capacity)
💡 Suggestion:
Try at least one of the following to free up space on the device:
1. Run "docker system prune" to remove unused docker data
2. Increase the amount of memory allocated to Docker for Desktop via
Docker icon > Preferences > Resources > Disk Image Size
3. Run "minikube ssh -- docker system prune" if using the docker container runtime
