# Minikube installation and cluster setup for indri
# Uses qemu2 driver for full VM with kernel mount capabilities (NFS, SMB, etc.)
#
# NOTE: minikube start may have issues when run via SSH.
# If cluster fails to start, manually run on indri:
#   minikube start --driver=qemu2 --container-runtime=containerd \
#     --cpus=6 --memory=12288 --disk-size=200g \
#     --apiserver-names=k8s.tail8d86e.ts.net --apiserver-names=indri \
#     --apiserver-port=6443 --listen-address=0.0.0.0
