# This sets up a Photon Controller with the tenant, project, flavors
# and image that are needed to deploy Kubernetes with kube-up.
#
# This is not meant to be used in production: it creates resource tickets
# (quotas) that are arbitrary and not likely to work in your environment.
# However, it may be a quick way to get your environment set up to try out
# a Kubernetes installation.
#
# It uses the names for the tenant, project, and flavors as specified in the
# config-common.sh file
#
# If you want to do this by hand, this script is equivalent to the following
# Photon Controller commands (assuming you haven't edited config-common.sh
# to change the names)
#
# photon target set https://192.0.2.2
# photon tenant create kube-tenant
# photon tenant set kube-tenant
# photon resource-ticket create --tenant kube-tenant --name kube-resources --limits "vm.memory 1000 GB, vm 1000 COUNT"
# photon project create --tenant kube-tenant --resource-ticket kube-resources --name kube-project --limits "vm.memory 1000 GB, vm 1000 COUNT"
# photon project set kube-project
# photon -n flavor create --name "kube-vm" --kind "vm" --cost "vm 1 COUNT, vm.cpu 1 COUNT, vm.memory 2 GB"
# photon -n flavor create --name "kube-disk" --kind "ephemeral-disk" --cost "ephemeral-disk 1 COUNT"
# photon image create kube.vmdk -n kube-image -i EAGER
#
# Note that the kube.vmdk can be downloaded as specified in the documentation.
