+# This workflow will build and push a node.js application to an Azure Web App when a commit is pushed to your default branch.
+#
+# This workflow assumes you have already created the target Azure App Service web app.
+# For instructions see https://docs.microsoft.com/en-us/azure/app-service/quickstart-nodejs?tabs=linux&pivots=development-environment-cli
+#
+# To configure this workflow:
+#
+# 1. Download the Publish Profile for your Azure Web App. You can download this file from the Overview page of your Web App in the Azure Portal.
+#    For more information: https://docs.microsoft.com/en-us/azure/app-service/deploy-github-actions?tabs=applevel#generate-deployment-credentials
+#
+# 2. Create a secret in your repository named AZURE_WEBAPP_PUBLISH_PROFILE, paste the publish profile contents as the value of the secret.
+#    For instructions on obtaining the publish profile see: https://docs.microsoft.com/azure/app-service/deploy-github-actions#configure-the-github-secret
+#
+# 3. Change the value for the AZURE_WEBAPP_NAME. Optionally, change the AZURE_WEBAPP_PACKAGE_PATH and NODE_VERSION environment variables below.

+# 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.
