Zerops x Gleam

This is the most bare-bones example of Gleam running on Zerops — as few libraries as possible, just a simple endpoint with connnect, read and write to a Zerops PostgreSQL database.

Recipe features

  • Wisp + Mist app running on a load balanced Zerops Gleam service
  • Zerops PostgreSQL 16 service as database
  • Built with wisp and mist for HTTP server functionality
  • Health check endpoint at /status
  • Utilization of Zerops' built-in environment variables system
  • Utilization of Zerops' built-in log management

Production vs. development

Base of the recipe is ready for production, the difference comes down to:

  • Use highly available version of the PostgreSQL database (change mode from NON_HA to HA in recipe YAML, db service section)
  • Use at least two containers for the Gleam service to achieve high reliability and resilience (add minContainers: 2 in recipe YAML, api service section)

Futher things to think about when running more complex, highly available Gleam production apps on Zerops:

  • containers are volatile - use Zerops object storage to store your files
  • use Zerops Redis (Valkey) for caching, storing sessions and pub/sub messaging
