Introducing the Dynamic Pipeline Stage Orchestrator

Introducing the Dynamic Pipeline Stage Orchestrator

In the domain of CI/CD, orchestrating complex workflows within Jenkins pipelines for continuous testing requires both adaptability and efficiency. This research introduces the "Dynamic Pipeline Stage Orchestrator," a framework designed to dynamically generate pipeline stages at runtime, based upon users' needs.

For any given service, there are some integration tests with a large execution time. Waiting for extended periods before production deployment is impractical, necessitating a more efficient approach to minimize these durations.   

The framework addresses this challenge by enabling users to predefine the number of stages in a YAML file, allowing tests to run in parallel to reduce test execution time. It lets the user group the tests using cucumber tags and associate each group with a pipeline stage and run in parallel. The Jenkins pipeline, unaware of the required number of stages beforehand, reads the configuration file at runtime, dynamically determines and creates the necessary stages, and executes. This approach ensures that the same pipeline framework, when executed for different services, generates a varying number of stages based on each service's configuration.   

Key Features

The entire configuration is done in a YAML file, and the pipeline framework reads it at runtime and performs the required action. Here is the list of major functionalities that can be achieved through the YAML configuration.

1. Dynamic Stage Creation: To optimize test execution time, each service can design its pipeline stages and execute them in parallel.

2. Confluence Upload: Users can configure the YAML file to upload Cucumber HTML reports to Confluence.

3. Stagewise Console Log Saving: For each stage, it generates a separate log file, simplifying the debugging process.

4. Consolidated Report Generator: It generates stage-wise Cucumber reports and combines all reports into a consolidated report for a comprehensive overview.

5. Deployment Rollback: Automatic rollback of deployments in case of stage failure can be configured through YAML, preventing progression to production deployment.

6. Notification to Slack and Email: Users can configure notifications to be sent to Slack or email upon the successful completion of a test execution, ensuring timely updates and communication.

7. Execution Support for Shell Commands: Through the YAML configuration, it is possible to execute a custom shell command to perform any specific action during test execution.

8.  Stage Orientation: Users can pre-define the mode of execution of stages, enhancing flexibility in pipeline design. For example, stage1|stage2->stage3, stage 1 and stage 2 will run in parallel, and after that, stage 3 will be executed.

Conclusion

This framework represents a significant advancement in the CI/CD process. By enabling the dynamic generation of pipeline stages at runtime, it provides a flexible and efficient solution. It optimizes the test execution times, thereby accelerating the overall deployment process. This innovation not only enhances the efficiency of Jenkins pipelines but also provides a scalable approach that adapts to the specific needs of different services. As a result, it ensures faster, more reliable, and streamlined production deployments, ultimately contributing to a more robust and agile development lifecycle.
