Overview
Administration is done with minikube.
Addons
minikube instance must be running for "addons" to work.
minikube addons list
minikube addons enable <addon-name>
Start
minikube start
minikube v1.12.3 on Darwin 10.14.6
✨ Automatically selected the docker driver
👍 Starting control plane node minikube in cluster minikube

🌟 Enabled addons: default-storageclass, storage-provisioner
🏄 Done! kubectl is now configured to use "minikube"
❗ /usr/local/bin/kubectl is version 1.16.6-beta.0, which may be incompatible with Kubernetes 1.18.3.
💡 You can also use 'minikube kubectl -- get pods' to invoke a matching version
Kubernetes Configuration at Startup
minikube start --extra-config=.... --extra-config=...
minikube start --extra-config=apiserver.enable-admission-plugins=PodSecurityPolicy
Custom Configuration Files
Files placed in ~/.minikube/files (including recursive directories) are transferred into minikube VM. A file placed in ~/.minikube/files/etc/tokens.csv is copied in the VM as /etc/token.csv.
Start with Admission Controller Enabled
See Enable Pod Security Policies below for an example how to start with a PodSecurityPolicy admission controller.

Delete
Deletes a local Kubernetes cluster. This command deletes the VM, and removes all associated files.
minikube delete --all --purge
--all deletes all profiles.
--purge deletes delete the '.minikube' folder from the user directory.
Enable Pod Security Policies
minikube stop
minikube start --extra-config=apiserver.enable-admission-plugins=PodSecurityPolicy --addons=pod-security-policy
CRI-O
Troubleshooting
minikube logs
minikube start --alsologtostderr --v=2
Obtaining details about kube-apiserver startup arguments:
kubectl -n kube-system describe pod kube-apiserver-minikube
SSH into the minikube VM:
minikube ssh
To get more details about IP and port:
minikube ssh --v=2 --alsologtostderr
Then you can use the IP address (127.0.0.1) and the port to connect via native SSH:
ssh docker@127.0.0.1 -p 32799 -i ~/.minikube/machines/minikube/id_rsa
For file transfer, a local directory can be mounted into the minikube VM (failed last time I tried it):
minikube mount ~/tmp/minikube:/tmp/temporary
Files can be transferred back and forth via scp:
scp -P 32799 -i ~/.minikube/machines/minikube/id_rsa docker@127.0.0.1:/var/tmp/minikube/kubeadm.yaml .
