#                   Open Match Script for Google Cloud Build                   #
################################################################################

# example command-line invocation:
# gcloud builds submit --config=cloudbuild.yaml --substitutions=_OM_VERSION=DEV .

# This YAML contains all the build steps for building Open Match.
# All PRs are verified against this script to prevent build breakages and regressions.

# Conventions
# Each build step is ID'ed with "Prefix: Description".
#   The prefix portion determines what kind of step it is and it's impact.
#   Docker Image: Read-Only, outputs a docker image.
#   Lint: Read-Only, verifies correctness and formatting of a file.
#   Build: Read-Write, outputs a build artifact. Ok to run in parallel if the artifact will not collide with another one.
#   Generate: Read-Write, outputs files within /workspace that are used in other build step. Do not run these in parallel.
#   Setup: Read-Write, similar to generate but steps that run before any other step.

# Some useful things to know about Cloud Build.
# When your build executes, Cloud Build copies the contents of your repository to /workspace, the default working directory for Cloud Build. 
# Learn more about working directories on the Build configuration overview page https://cloud.google.com/build/docs/build-config-file-schema
#   - Modifications that occur within /workspace are persisted between build steps.
#   - If you want to replicate the build process from this file locally, you'll need to
#     clone the open match github repo and set HEAD to the commit you're trying to build. 
# If a build step has intermediate files that need to be persisted for a future step then use volumes.
#    An example of this is the go-vol which is where the pkg/ data for go mod is stored.
#    More information here: https://cloud.google.com/cloud-build/docs/build-config#build_steps
# A build step is basically a docker image that is tuned for Cloud Build,
#    https://github.com/GoogleCloudPlatform/cloud-builders/tree/master/go
