# 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) | |
# | |
