Tekton is an open-source framework for creating CI/CD systems. It allows developers to build, test, and deploy across cloud providers and on-premise systems. Tekton provides a set of Kubernetes CRDs (Custom Resource Definitions) for defining and running continuous integration and continuous delivery pipelines.
When working with Tekton, you might encounter a situation where a PipelineRun
fails due to a step exceeding its timeout. This is typically observed in the logs where a specific step does not complete within the expected time frame, leading to a timeout error.
The error message might look like this:
Error: Step "step-name" in TaskRun "taskrun-name" exceeded its timeout.
A step timeout occurs when a step in a PipelineRun
takes longer to execute than the specified timeout duration. This can happen due to various reasons such as network latency, resource constraints, or inefficient task execution.
The root cause is often related to the step's configuration in the PipelineRun
spec. If the timeout is set too low for the task at hand, it can lead to premature termination of the step.
To resolve the step timeout issue, you can increase the timeout duration for the specific step in the PipelineRun
spec. Follow these steps:
First, identify which step in the PipelineRun
is timing out. You can do this by reviewing the logs of the PipelineRun
and identifying the step that fails with a timeout error.
Once you have identified the step, modify the PipelineRun
spec to increase the timeout. Open the YAML configuration file for the PipelineRun
and locate the step configuration. It should look something like this:
apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
name: example-pipelinerun
spec:
pipelineSpec:
tasks:
- name: example-task
taskSpec:
steps:
- name: step-name
image: example-image
script: |
# Your script here
timeout: "1h"
Increase the timeout
value to a duration that is sufficient for the step to complete. For example, change timeout: "1h"
to timeout: "2h"
if needed.
After modifying the PipelineRun
spec, apply the changes using the following command:
kubectl apply -f pipelinerun.yaml
This command updates the PipelineRun
with the new timeout settings.

By following these steps, you should be able to resolve the step timeout issue in your Tekton PipelineRun
and ensure that your CI/CD pipelines run smoothly.
