# Makefile for deploying redirector on Google Cloud Platform.
#
# To customize for personal use:
# * Change gs_redirector to refer to your own Google Cloud Storage bucket.
# * make install-redirector
#
# To add a new host:
# * Copy the start-rsc-io stanza and customize VM name, address name, import= and repo=.
# * Adjust certs= to point to a gs:// directory containing <host>.crt and <host>.key,
# or delete that metadata entry to disable serving with HTTPS.
# * make newip-your-vm to get an IP address.
# * make start-your-vm to start the VM.
#
# To ssh into a host (to debug):
# * make ssh-your-vm
#
# To restart a host:
# * make stop-your-vm
# * make start-your-vm

# Start VM for rsc.io. The VM name is rsc-io, as is the name for the IP address
# (acquired via 'make newip-rsc-io'). Using the debian-7 image is important
# because it has the startup-script support (Ubuntu does not).
# The f1-micro instance seems to be plenty of power for this use and costs ~$100/year.
# The gce-startup-script file is copied to the VM and runs at startup.
# It reads the three metadata variables at the end of the script, copies the
# redirector from the first one (redirector=) and then invokes it with the
# arguments given by the second and third (import= and repo=).
