This is the most bare-bones example of a Ruby Sinatra app running on Zerops — as few gems as possible, just a simple endpoint with connect, read and write to a Zerops PostgreSQL database.
You can either click the deploy button to deploy directly on Zerops, or manually copy the import yaml to the import dialog in the Zerops app.
- Ruby with Sinatra on a load balanced Zerops Ruby service
- Zerops PostgreSQL 16 service as database
- Healthcheck setup example via
/statusendpoint - Utilization of Zerops' built-in environment variables system through dotenv
- Utilization of Zerops' built-in log management with various log levels
Base of the recipe is ready for production, the difference comes down to:
- Use highly available version of the PostgreSQL database (change
modefromNON_HAtoHAin recipe YAML,dbservice section) - Use at least two containers for the Ruby service to achieve high reliability and resilience (add
minContainers: 2in recipe YAML,apiservice section)
Further things to think about when running more complex, highly available Ruby production apps on Zerops:
- Containers are volatile - use Zerops object storage to store your files
- Use Zerops Redis (KeyDB) for caching, storing sessions and pub/sub messaging
- Consider using Puma or Unicorn as production-ready application servers
- Use more advanced logging tools such as the Ruby port of structured logging libraries
