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 for defining cloud-native CI/CD pipelines.
When working with Tekton, you might encounter an error message stating 'Task not found'. This typically occurs when a Task is referenced in a PipelineRun or TaskRun, but Tekton cannot locate it in the specified namespace.
The error message might look like this:
Error: Task 'example-task' not found in namespace 'default'.
The 'Task not found' error indicates that the Task you are trying to execute does not exist in the namespace where the PipelineRun or TaskRun is being executed. This can happen due to several reasons, such as the Task being deleted, not created, or being in a different namespace.
To resolve the 'Task not found' error, follow these steps:
First, ensure that the Task exists in the correct namespace. You can list all Tasks in a namespace using the following command:
kubectl get tasks -n <namespace>
Replace <namespace> with the appropriate namespace name.
If the Task does not exist, you need to create it. You can apply the Task YAML file using:
kubectl apply -f task.yaml -n <namespace>
Ensure that the YAML file is correctly configured and points to the right namespace.
Ensure that the PipelineRun or TaskRun is configured to use the correct namespace. Check the YAML configuration for the namespace field:
apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
name: example-pipelinerun
namespace: <namespace>
Make sure the namespace matches where the Task is located.

By following these steps, you should be able to resolve the 'Task not found' error and ensure your Tekton pipelines run smoothly.
