# USAGE:
# 0: Install `docker` and `terraform` (Process specific to your system)
# 1: Copy the sample.env file to .env
# 2: Fillout the GCP info in .env
# 3: Edit GCP_REPO to the correct docker image repo path if you are using something other than Container registry
# 4: Edit the PREFIX if you would like images and GKE entities to be prefixed with something else
# 5: Run `make init` to initialize terraform
# 6: Follow the normal Preplexica configuration steps outlined in the project readme
# 7: Run `make build-deplpy` to build and push the project images to the repo, create a GKE cluster and deploy the app
#
# NOTES/ WARNINGS:
# - The app endpoint is unsecured and exposed to the internet at large, you will need to implement your desired auth
# - No auto scaling is enabled for this cluster and deployments, edit the terraform files accordingly for that
include .env

# Use `location-id-docker.pkg` for artifact registry Ex. west-1-docker.pkg
