It covers creating a MongoDB replica set with three pods using the official Helm chart, packaging a Node.js app as a Docker image, building a custom Helm chart for the application, and configuring environment variables through ConfigMaps and Secrets. The tutorial demonstrates how to connect the stateless Node.js layer to the stateful MongoDB replica set using DNS entries, implement health checks, and verify data replication across database instances. It includes practical steps for scaling replicas and troubleshooting common issues. ## Full article daily.dev links to this article rather than hosting it.
