deploy

To deploy a Rails application with Docker and Kamal, you need a multi-stage Dockerfile and Kamal 2 configuration. This generates zero-downtime deployment scripts, Thruster HTTP/2 proxy settings, and Puma server configurations for production environments.

The Solid Trifecta uses solid_queue, solid_cache, and solid_cable to replace Redis in Rails deployments. Configuration involves setting up database-backed Queue, Cache, and Cable layers within your Docker container architecture instead of external dependencies.

Yes, Kamal deploys Ruby and Grape apps to AWS ECS, Kubernetes, Heroku, and Fly.io. The deployment generates appropriate cloud platform manifests, health checks, and environment variable configurations specific to your chosen infrastructure.

Docker deployments handle database migrations and asset precompilation through multi-stage Dockerfile templates and safe migration strategies. This ensures environment variables, secrets, and assets are verified via a pre-release checklist before deployment.

Configuring Thruster HTTP/2 proxy with Puma involves installing Thruster and integrating it as the front-facing proxy. This architecture pairs Thruster with Puma and the Solid Trifecta behind a load balancer for optimized Rails request handling.

Yes, Kamal 2 zero-downtime deployments require multi-stage Dockerfile templates for building and running the app. You also need appropriate health check implementations and environment variable definitions to ensure safe release transitions.
