#cloud-config

# This config is an example of of a one-liner to getting a CSGO server up-and-running
# in just a few minutes on Google Compute Engine with the following one-liner that consumes
# the uncommented parts of this file:
#
# gcloud compute instances create csgo-server \
#     --project=$PROJECT \
#     --zone=$ZONE \
#     --image-family=cos-stable \
#     --image-project=cos-cloud \

#     --machine-type=c2-standard-4 \
#     --network=default \
#     --metadata-from-file user-data=$(PWD)/cloud-config.yaml
