Deploy and Host Harness Open Source

What is Harness Open Source?
Harness Open Source is an end-to-end, open source developer platform that combines source code management (SCM), continuous integration/continuous delivery (CI/CD), hosted development environments, and an artifact registry into a unified solution.

About Hosting Harness Open Source

Hosting Harness Open Source involves deploying all the core services—code repository hosting, CI/CD pipelines, cloud development environments (Gitspaces), and an artifact registry—in one stack. It is designed for rapid setup via container or Docker-based deployments, with environment variables for configuration and all state backed by volumes or databases. You’ll need to provide persistent storage, set up your database backend (for example PostgreSQL or another supported datastore), expose necessary ports, and configure your SCM integrations. The open-source platform supports self-hosting, giving you full control of your development lifecycle, while offering scalability and flexibility to handle multiple teams and workflows.

Common Use Cases

• Repository and SCM hosting: Host your private Git repositories, handle pull-requests, branch protections, code reviews and secret scanning.
• CI/CD pipelines: Build, test, and deploy applications across multiple languages and platforms with triggered pipelines, matrix builds, and parallel jobs.
• Artifact registry + developer environments: Store Docker images, Helm charts and other artifacts in a central registry, and provide on-demand cloud development environments to accelerate onboarding and developer productivity.

Dependencies for Harness Open Source Hosting

• Harness Open Source application stack (Docker image or containerized services)
• Database backend (e.g., PostgreSQL) for repository metadata, pipeline state, and user management
• Persistent volumes to store repository data, build artifacts, logs, and development environment state

Deployment Dependencies

• Harness Open Source GitHub Repository — source code, Docker images, installation instructions.
• Harness Open Source Documentation — detailed guides for pipelines, registries, Gitspaces, SCM.
• Harness Open Source Main Site — overview of features and open-source offering.
