# This workflow build and push a Docker container to Google Artifact Registry and deploy it on Google Kubernetes Engine when a commit is pushed to the "develop" branch
# You can start your commit with `#update` and the workflow will just trigger an update of the Helm installation, without building a new image
#
# To configure this workflow:
#
# 1. Ensure the required Google Cloud APIs are enabled in the project:
#
# Cloud Build cloudbuild.googleapis.com
# Kubernetes Engine API container.googleapis.com
# Artifact Registry artifactregistry.googleapis.com
#
# 2. Create a service account (if you don't have one) with the following fields:
#
# Service Account Name <PROJECT-NAME>-github-actions
# Service Account ID <PROJECT-NAME>-github-actions
#
# 3. Ensure the service account have the required IAM permissions granted:
#
# Kubernetes Engine Developer
# roles/container.developer (kubernetes engine developer)
#
# Artifact Registry
# roles/artifactregistry.repoAdmin (artifact registry repository administrator)
# roles/artifactregistry.admin (artifact registry administrator)
#
# Service Account
# roles/iam.serviceAccountUser (act as the Cloud Run runtime service account)
#
# Basic Roles
# roles/viewer (viewer)
#
# NOTE: You should always follow the principle of least privilege when assigning IAM roles
#
# 4. Ensure you have the following GitHub Secrets and Variables:
#
# GitHub Secrets
# GCP_SA_KEY (Google Cloud Project Service Account Key) ref visit https://github.com/Datawheel/company/wiki/Setting-Up-a-Service-Account-for-Workflows#use-the-service-account-on-github-secrets
#
# GitHub Variables
# GCP_PROJECT_ID (Google Cloud Project ID)
# GCP_ARTIFACT_REGISTRY_NAME (Google Cloud Articaft Registry Repository Name)
# GCP_ARTIFACT_REGISTRY_LOCATION (Google Cloud Artifact Registry Reposotiry Location)
#
# 5. Ensure you have the following GitHub Variables for each environment that you will set up:
#
# GitHub Variables
# GCP_IMAGE_NAME (Docker Image Name)
# GKE_APP_NAME (Google Kubernetes Engine Deployment Name)
# GKE_APP_NAMESPACE (Google Kubernetes Engine Deployment Namespace)
# GKE_CLUSTER (Google Kubernetes Engine Cluster Name)
# GKE_ZONE (Google Kubernetes Engine Cluster Zone)
#
