# If spot_price is null, it will create an on-demand EC2 instance. This is
# more expensive, but more stable. Spot instances can save you up to 90%
# on-demand prices; but they can be pulled out from under you (killing
# your gaming session). It's a bidding model, the higher your bid, the more
# likely you are to keep your instance online. I suggest setting the price higher
# than the price of the on-demand instance ($2 instead of $1.5 in this case).
# So MOST of the time you'll be at the cost-saving; but when demand is pushing
# you, your high-bid is likely to keep you online. Set this to null (or don't
# include it) if you don't ever want a gaming session killed; and you're willing
# to pay a premium for that. Set it to a number if you're willing to have
# sessions killed, with the benefit of $$$ savings.

# Note: you might need to request a Spot Instance quota increase (from 0 to 1);
# EC2 disables Spot Requests by default in some cases. Go to AWS > <search for
# "service quotas" > EC2. Create a request for "All G and VT Spot Instance Requests"
# setting "new request" from 0 to 1. They grant this manually, so it could take some
# days. If you want to get started, set below to `null` and do the Spot thing later.
