# This workflow will build a docker container, publish it to Google Container
|
|
# Registry, and deploy it to GKE when there is a push to the "main"
|
|
# branch.
|
|
#
|
|
# To configure this workflow:
|
|
#
|
|
# 1. Enable the following Google Cloud APIs:
|
|
#
|
|
# - Artifact Registry (artifactregistry.googleapis.com)
|
|
# - Google Kubernetes Engine (container.googleapis.com)
|
|
# - IAM Credentials API (iamcredentials.googleapis.com)
|
|
#
|
|
# You can learn more about enabling APIs at
|
|
# https://support.google.com/googleapi/answer/6158841.
|
|
#
|
|
# 2. Ensure that your repository contains the necessary configuration for your
|
|
# Google Kubernetes Engine cluster, including deployment.yml,
|
|
# kustomization.yml, service.yml, etc.
|
|
#
|
|
# 3. Create and configure a Workload Identity Provider for GitHub:
|
|
# https://github.com/google-github-actions/auth#preferred-direct-workload-identity-federation.
|
|
#
|
|
# Depending on how you authenticate, you will need to grant an IAM principal
|
|
# permissions on Google Cloud:
|
|
#
|
|
# - Artifact Registry Administrator (roles/artifactregistry.admin)
|
|
# - Kubernetes Engine Developer (roles/container.developer)
|
|
#
|
|
# You can learn more about setting IAM permissions at
|
|
# https://cloud.google.com/iam/docs/manage-access-other-resources
|
|
#
|
|
# 5. Change the values in the "env" block to match your values.
