Dokku

Dokku is a lightweight platform-as-a-service (PaaS) that runs on a single server and uses Docker to build, deploy, and manage applications. It provides a Heroku-like workflow where you push code via Git and Dokku handles containerized runtime and app lifecycle.

Key Features

• Git push deployments with Heroku-compatible workflow
• App builds via Heroku buildpacks or Dockerfile-based deployments
• Per-app container isolation and process management
• Plugin system for add-ons such as databases, caches, and other services
• Built-in management for domains, environment variables, and SSL/TLS certificates

Use Cases

• Hosting multiple small-to-medium web apps on a single VM with simple deploys
• Replacing managed PaaS for personal projects or small teams with full server control
• Running a consistent deployment workflow across many languages supported by buildpacks

Limitations and Considerations

• Designed primarily for single-host operation; advanced multi-node orchestration is outside its core scope
• Operational responsibilities (backups, monitoring, capacity planning) remain with the operator

Dokku is well-suited for teams that want an easy, Heroku-style deployment experience without adopting a full cluster platform. It combines a familiar Git-based workflow with Docker containers and a flexible plugin ecosystem for common hosting needs.
