Spotify Backstage on AKS

My deployment of backstage.io on a Kubernetes cluster.

Suppporting infrastructure

• AKS cluster
• PostgreSQL database
• Azure Application Gateway Ingress Controller

PostgreSQL

This is a standard PostgreSQL deployment, with a Persistent Volume for storage, a Secret with authentication credentials, and a Service for Backstage <-> PostgreSQL networking.

Application Gateway

The Azure Application Gateway is installed via Helm, using the helm-config.yaml as the values file. It watches for any Ingress resources created in the cluster and provisions a load balancer in order to serve traffic to Backstage. The App Gateway IngressClass is set on the Backstage Ingress resource to wire things up:

ingressClassName: azure-application-gateway

Backstage configuration

Backstage is compiled into the ericpaulsen/backstage:latest image, with the configuration living in /app/app-config.yaml. Here's the Backstage documentation on building the application into a Docker image.
