Zuul is a project gating system that drives continuous integration, delivery and deployment workflows.
It focuses on testing proposed changes before they are merged, helping development teams keep their main branches in a working state.
The software can test multiple dependent changes and repositories together, including changes hosted on different code-review platforms. Zuul executes jobs as Ansible playbooks and supports complex, multi-node testing and deployment processes.
This is free and open source software.
Key Features
- Prevents changes from being merged until their required tests have completed successfully.
- Tests speculative future repository states before changes enter the main branch.
- Runs tests for multiple queued changes in parallel while preserving their dependency order.
- Supports dependencies between changes in separate repositories and across different hosting services.
- Integrates with Gerrit, GitHub, GitLab and other source-code systems.
- Defines CI and deployment jobs using Ansible playbooks.
- Supports job inheritance, reusable project templates and dependent job graphs.
- Prepares repositories with proposed and dependent changes already merged for testing.
- Provides support for multi-node test and deployment environments.
- Offers a web dashboard, REST API and real-time build-log streaming.
- Supports multiple tenants with independently managed projects and configurations.
- Emits operational metrics through the StatsD protocol.
