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 provides a set of Kubernetes Custom Resources (CRDs) that enable you to define pipelines, tasks, and other CI/CD components declaratively.
When working with Tekton, you might encounter a situation where a PipelineRun fails. This is a common issue that developers face, and it typically manifests as an error message indicating that the PipelineRun did not complete successfully.
The error message might look something like this:
PipelineRun failed: One or more TaskRuns within the PipelineRun failed.
The failure of a PipelineRun is often due to one or more TaskRuns within the pipeline failing. Each TaskRun represents an execution of a task, and if any of these tasks encounter an error, the entire pipeline can fail.
To resolve a failed PipelineRun, you need to inspect the logs of the failed TaskRuns to identify the specific errors. Here are the steps to do so:
First, list all TaskRuns associated with the failed PipelineRun:
kubectl get taskruns -l tekton.dev/pipelineRun=
Replace <PipelineRunName> with the name of your failed PipelineRun.
Next, inspect the logs of each TaskRun to identify the error:
tkn taskrun logs -f
Replace <TaskRunName> with the name of the TaskRun you want to inspect. The tkn CLI tool is part of the Tekton CLI, which you can install from the Tekton CLI GitHub repository.
Once you identify the error, take appropriate action to fix it. This might involve:
By following these steps, you can diagnose and resolve issues that cause a PipelineRun to fail in Tekton. For more detailed information, refer to the Tekton PipelineRuns documentation.
