Dokku
Create a personal PaaS on any server. Push Heroku-compatible applications via Git and let Docker build and run them in isolated containers. No vendor lock-in.
Dokku is an open-source Platform as a Service that you can run on your own hardware, giving you a powerful alternative to services like Heroku. Powered by Docker, it helps you build and manage the entire lifecycle of your applications. Once configured on a host, you can deploy applications simply by pushing your code via Git.
The platform automatically builds your application using standard Heroku buildpacks and runs it within an isolated container. This provides you with your own personal, single-host version of Heroku without the associated costs or vendor lock-in.
Key features include:
- Total Control: Install it on any server, from a low-cost cloud provider to a Raspberry Pi.
- Git-Based Workflow: Deploy your applications using the familiar
git pushcommand. - Plugin Architecture: Extend its functionality with a rich ecosystem of plugins for databases, caching, SSL certificates, and more.
- No Vendor Lock-in: Own your infrastructure and avoid being tied to a single provider's ecosystem.
