Tekton is a powerful and flexible open-source framework for creating CI/CD systems. It allows developers to define and run continuous integration and delivery pipelines in Kubernetes. Tekton Pipelines are designed to automate the process of building, testing, and deploying code, making it easier to manage and scale CI/CD workflows.

One common issue developers encounter when working with Tekton is a step in the PipelineRun being skipped. This can be frustrating as it may halt the progress of your CI/CD pipeline unexpectedly. The symptom is typically observed in the PipelineRun logs, where a specific step is marked as skipped.
In Tekton, steps within a PipelineRun can be skipped if certain conditions are not met. Conditions are used to control the execution flow of the pipeline, allowing for more dynamic and flexible workflows. If a condition evaluates to false, the associated step will be skipped.
Skipped steps often result from misconfigured conditions or logical errors in the pipeline definition. It is crucial to ensure that conditions are correctly defined and that they reflect the intended logic of the pipeline.
Start by examining the logs of the PipelineRun to identify which step was skipped and why. You can retrieve the logs using the following command:
tkn pipelinerun logs <pipeline-run-name> --follow
Look for messages indicating that a step was skipped and note any conditions mentioned.
Check the conditions associated with the skipped step in the pipeline definition. Ensure that they are correctly defined and that the logic aligns with your pipeline's requirements. For example, if a condition depends on a specific resource or parameter, verify that it is available and correctly configured.
After making adjustments to the conditions, test the PipelineRun again to see if the issue is resolved. You can trigger a new PipelineRun using:
tkn pipeline start <pipeline-name> --param <param-name>=<value>
Monitor the logs to ensure that the previously skipped step now executes as expected.
For more detailed information on configuring conditions in Tekton, refer to the Tekton Conditions Documentation. Additionally, the Tekton GitHub repository is a valuable resource for exploring examples and community discussions.
By following these steps, you should be able to diagnose and resolve issues related to skipped steps in Tekton PipelineRun, ensuring a smooth and efficient CI/CD workflow.
