# Use this instead of directly selecting Dockerfile option in the build trigger, as we need to use this file to instruct on how to deploy as well.
steps:
# Build the container image
- id: tardsquad-discord-bot-build
  name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'us.gcr.io/tardsquad-discord-bot/tardsquad-discord-bot', '.']
# Push the container image to Container Registry
- id: tardsquad-discord-bot-push
  name: 'gcr.io/cloud-builders/docker'
  args: ['push', 'us.gcr.io/tardsquad-discord-bot/tardsquad-discord-bot']
# Deploy container image to Cloud Run
#- id: tardsquad-discord-bot-deploy
  #name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'
  #entrypoint: gcloud
  #args: ['run', 'deploy', 'tardsquad-discord-bot', '--image', 'us.gcr.io/tardsquad-discord-bot/tardsquad-discord-bot', '--region', 'us-central1']
# Deploy container image to Compute Engine
# Requires that the Clould Build service account has Compute Engine permissions, which can be set in iAM but easiest at
#  https://console.cloud.google.com/cloud-build/settings/service-account?project=tardsquad-discord-bot
# Ref: https://cloud.google.com/compute/docs/containers/deploying-containers#updating_a_container_on_a_vm_instance
- id: tardsquad-discord-bot-deploy
  name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'
  entrypoint: gcloud
  args: ['compute', 'instances', 'update-container', '--project=tardsquad-discord-bot', '--zone=us-central1-a', '--container-image', 'us.gcr.io/tardsquad-discord-bot/tardsquad-discord-bot:latest', 'tardbot-vm']
# Delete storage bucket
# Container Registry automatically creates a Cloud Storage Bucket that is multi-regional. However the free tier for Cloud Storage only has regional included.
# Possible workaround is to use a custom build trigger: https://stackoverflow.com/a/60983361/265508
# Another hack: delete undelaying Bucket after deployment: https://stackoverflow.com/a/70821159/265508
# Con: can't reboot the Compute Engine VM, as the image is now gone. Instead have to trigger a rebuild from Trigger UI.
# Note: the command succeeds and prints deleted files, but they are still visible in the bucket UI...
