# Cyclone

-Cyclone is a cloud native workflow engine not only for CI/CD pipelines, but also for general workflows. It defines workflow by assembling workflow stages as DAG. As Cyclone totally bases on Kubernetes, it can be easily deployed and used.
+Cyclone is a powerful workflow engine and end-to-end pipeline solution implemented with native Kubernetes resources,
+with no extra dependencies. It can run anywhere Kubernetes is deployed: public cloud, on-prem or hybrid cloud.
-Cyclone defines each workflow stage as a pod, and assemble them to workflow by capturing dependencies between stages as DAG.
+Cyclone is architectured with a low-level workflow engine that is application agnostic, offering capabilities like
+workflow DAG scheduling, resource lifecycle management and most importantly, a pluggable and extensible framework for
+extending the core APIs. Above which, Cyclone provides built-in support for high-level functionalities, with CI/CD
+pipelines and AI DevOps being two notable examples, and it's possible expand to more use cases as well.
+
+With Cyclone, users end up with the flexibility of workflow orchestration and the usability of complete solutions.
## Features
-- **Kubernetes Native**: Totally based on Kubernetes without any other dependencies..
-- **Workflow Engine**: Supports CI/CD pipelines, AI pipelines and any other general workflows.
-- **DAG**: Cyclone supports any DAG workflow.
-- **Pluggability**: Cyclone can easily integrate with external systems, such as SCM, Docker Registry, S3, etc.
-- **Triggers**: Workflow can be triggered by time schedule, webhooks.
-- **Controllable**: Execution of workflow can be paused, resumed or cancelled.
-- **Multi-Tenant**: Cyclone supports multi-tenant.
-- **Garbadge Collection**: Cleanup after workflow finished and results collected.
+
+- DAG graph scheduling: Cyclone supports DAG workflow execution
+- Parameterization: stage (unit of execution) can be parameterized to maximize configuration reuse
+- External dependencies: external systems like SCM, docker registry, S3 can be easily integrated with Cyclone
+- Triggers: Cyclone supports cron and webhook trigger today, with upcoming support for other types of triggers
+- Controllability: workflow execution can be paused, resumed, retried or cancelled
+- Multi-cluster: workflow can be executed in different clusters from where Cyclone is running
+- Multi-tenant: resources manifests and workflow executions are grouped and isolated per tenant
+- Garbadge Collection: automatic resource cleanup after workflow execution
+- Logging: logs are persisted and indpendent from workflow lifecycle, enabling offline inspection
+- Built-in Pipeline: curated DAG templates and stage runtimes for running DevOps pipelines
## Quick Start
Build images
+
```bash
$ make container
```
Deploy to Kubernetes cluster
+
```bash
$ kubectl create -f manifests/cyclone.yaml
```

+## Contributing
+
+If you are interested in contributing to Cyclone, please checkout [CONTRIBUTING.md](./CONTRIBUTING.md).
+We welcome any code or non-code contribution!
-Before v0.9.0, Cyclone focuses on CI/CD pipelines and run pipelines in both Docker and Kubernetes.
+## Licensing
-From v0.9.0, Cyclone has been totally refactored, new Cyclone not only aims at CI/CD pipeline, but also provides a general workflow engine. Compared with previous one, it's more flexible and powerful.
