Workflow
# creates a new Kindfile (edit for your needs)
$ kindtool init -d <projectdir>

# creates the cluster - this will create a .kind directory next to Kindfile
$ kindtool up

# kills the kind cluster - configuration, k8s config is removed,
# the persistent data will be kept in .kind/data
$ kindtool destroy

# kills the kind cluster and removes the data folder
# this needs to be run as root! Docker might created files that have 0/0 uids/gids
$ sudo kindtool destroy -f

# is kind running - print status information
$ kindtool status

# start the k8s dashboard
$ kindtool dashboard

# returns the directory with the config files
# can be used as export KUBECONFIG=$(kindfile get kubeconfig)
$ kindtool get kubeconfig
