  metadata:
    name: backstage
  spec:
    replicas: 1
    selector:
      matchLabels:
        app: backstage
    template:
      metadata:
        labels:
          app: backstage
      spec:
        containers:
        - name: backstage
          image: your-docker-image
          ports:
          - containerPort: 7000
  

This YAML file defines a deployment resource for your Backstage application, specifying the Docker image to use and the port to expose. Once your deployment resource is ready, apply it to your Kubernetes cluster using kubectl.

Run the following command to apply your Kubernetes pod deployment:

kubectl apply -f backstage-deployment.yaml

With your deployment resource applied, your Backstage application will be up and running on Kubernetes. In the next section, we’ll configure a PostgreSQL database for persistent storage.

Configuring a PostgreSQL Database

A PostgreSQL database is essential for Backstage, providing the persistent storage needed for your applications. Configuring this database on Kubernetes involves creating a separate deployment resource for PostgreSQL. This ensures that your database remains isolated from the Backstage application, enhancing stability and performance.

To set up PostgreSQL, start by creating a Docker image for the database. You can use an existing PostgreSQL image from Docker Hub or build your own if you have specific requirements. Once you have your image, create a Kubernetes deployment YAML file for PostgreSQL.

Here’s a basic example of a PostgreSQL deployment YAML:

  apiVersion: apps/v1
  kind: Deployment
  metadata:
    name: postgres
  spec:
    replicas: 1
    selector:
      matchLabels:
        app: postgres
    template:
      metadata:
        labels:
          app: postgres
      spec:
        containers:
        - name: postgres
          image: postgres:latest
          env:
          - name: POSTGRES_DB
            value: backstage
          - name: POSTGRES_USER
            value: postgres
          - name: POSTGRES_PASSWORD
            value: yourpassword
          ports:
          - containerPort: 5432
  

Apply this configuration using kubectl to deploy PostgreSQL to your Kubernetes cluster. This setup provides a reliable database for your Backstage application, ensuring data persistence and integrity.

Setting Up Kubernetes Service and Ingress

With your Backstage and PostgreSQL deployments in place, the next step is to set up a Kubernetes Service and Ingress. These components manage how your applications receive traffic and communicate within the cluster.

First, create a Kubernetes Service for your Backstage application. This service exposes your application to the network, allowing it to receive external traffic. Here’s an example YAML configuration for a Backstage service:

  apiVersion: v1
  kind: Service
  metadata:
    name: backstage-service
  spec:
    selector:
      app: backstage
    ports:
    - protocol: TCP
      port: 80
      targetPort: 7000
    type: LoadBalancer
  

Apply this configuration to your cluster using kubectl. Once the service is up, configure an Ingress resource to manage external access to your application. The Ingress resource routes external HTTP/S traffic to your Backstage service, providing a single point of entry.

Here’s an example of an Ingress resource configuration:

  apiVersion: networking.k8s.io/v1
  kind: Ingress
  metadata:
    name: backstage-ingress
  spec:
    rules:
    - host: your-domain.com
      http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
              name: backstage-service
              port:
