Tekton is a powerful and flexible open-source framework for creating CI/CD (Continuous Integration and Continuous Deployment) systems. It allows developers to define and run pipelines, which are sequences of tasks that automate software development processes. Tekton is designed to be cloud-native and integrates seamlessly with Kubernetes, making it an ideal choice for modern cloud-based development workflows.
When working with Tekton, you might encounter a situation where a PipelineRun appears to be missing. This symptom is typically observed when you expect a pipeline to execute, but there is no evidence of its initiation or completion in the system logs or user interface.
PipelineRun resources when querying the Kubernetes cluster.The missing PipelineRun issue often arises when the PipelineRun resource was not created or was inadvertently deleted. This can happen due to several reasons, such as misconfigurations, manual deletions, or issues in the pipeline definition that prevent the creation of a PipelineRun.
PipelineRun resource.To address the issue of a missing PipelineRun, follow these steps:
First, ensure that the PipelineRun was created successfully. Use the following command to list all PipelineRun resources in your namespace:
kubectl get pipelineruns -n <your-namespace>
If the PipelineRun is not listed, it may not have been created.
Review the YAML configuration of your pipeline to ensure there are no syntax errors or misconfigurations. Validate your YAML files using tools like YAML Checker to catch any issues.
If the PipelineRun was created but is now missing, check for any deletion events. Use the following command to view recent events in your namespace:
kubectl get events -n <your-namespace>
Look for any events indicating that the PipelineRun was deleted.
Ensure that the service account used by Tekton has the necessary permissions to create and manage PipelineRun resources. Check the role bindings and adjust them if necessary.
By following these steps, you should be able to diagnose and resolve the issue of a missing PipelineRun in Tekton. For more detailed information, refer to the Tekton Pipelines Documentation. Ensuring proper configuration and permissions will help prevent similar issues in the future.
