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 using Kubernetes resources. Tekton provides a set of Kubernetes Custom Resource Definitions (CRDs) for defining pipelines, tasks, and other CI/CD constructs.
For more information, you can visit the official Tekton website.
When working with Tekton, you might encounter an error message stating that a TaskRun artifact is not found. This typically occurs when a TaskRun attempts to access an artifact that has not been produced or is missing from the expected location.
The "TaskRun artifact not found" error indicates that a specific artifact expected by a TaskRun is unavailable. This can happen due to several reasons, such as:
Understanding the root cause is crucial for resolving the issue effectively.
Ensure that the task responsible for producing the artifact has executed successfully. You can check the logs of the TaskRun using the following command:
kubectl logs taskrun/ -n
Look for any errors or warnings that might indicate why the artifact was not produced.
Verify that the artifact is stored in the correct location. If you are using a persistent volume or an external storage solution, ensure that the storage configuration is correct and accessible. Check the storage path specified in the TaskRun or PipelineRun definitions.
Examine the Task and Pipeline definitions to ensure that the artifact paths are correctly specified. Pay attention to the workspaces and results sections in your YAML files. For more details on configuring workspaces, refer to the Tekton Workspaces documentation.
After making the necessary corrections, re-run the pipeline to see if the issue is resolved. Use the following command to start the pipeline:
tkn pipeline start -n
Monitor the pipeline execution to ensure that the artifact is produced and accessible as expected.
By following these steps, you should be able to diagnose and resolve the "TaskRun artifact not found" issue in Tekton. Ensuring that artifacts are correctly produced and stored is crucial for the smooth execution of CI/CD pipelines.
