Prerequisites

The provided Kubernetes manifests are meant to be applied to Google Kubernetes Engine cluster. You need to prepare the following things:

• Create a cluster in Google Kubernetes Engine
• Configure kubectl and gcloud CLI to connect to the cluster, you can follow this guide.
• Reserve a static IP address for the Ingress, you can follow this guide. The name of this IP will be put in the Ingress's manifest, under kubernetes.io/ingress.global-static-ip-name annotation.

Steps

• If there is an .env.example file in the manifest directory, copy it to a .env file within the same directory then fill in the values. Here is an example.

• The environment variables for the frontend is an exception, it should be set in its Dockerfile. I am still working on this.

• Go to the deployment scripts directory, then run the following in order:

  • ./deploy-infrastructure.sh
  • ./deploy-database-migrator.sh
  • ./deploy-backend.sh
  • ./deploy-frontend.sh
  • ./deploy-ingress.sh
