Dokku

What is Dokku?

Dokku is an open-source Platform-as-a-Service (PaaS) solution built on Docker that enables developers to deploy applications without managing complex infrastructure. It provides a lightweight alternative to commercial PaaS offerings like Heroku by allowing users to run their own deployment platform on a single server. The platform simplifies application deployment through a Git-based workflow, where developers can push code to trigger automatic builds and deployments. Dokku supports multiple programming languages and frameworks through Docker containerization, making it flexible for various project types. Dokku is designed for developers and small teams who want to maintain control over their deployment infrastructure while avoiding the overhead of managing Kubernetes or other complex orchestration tools. It eliminates the need for dedicated DevOps expertise while providing essential features like SSL certificate management, environment variable configuration, and application scaling. Being fully open-source and free, Dokku reduces hosting costs compared to managed PaaS solutions. Installation is straightforward through a bootstrap script, and it can run on any standard Linux server. The project is actively maintained with packages available for Ubuntu and Arch Linux, supported by an active community and comprehensive documentation.
