Identifying the Symptom: PipelineRun Skipped

One common issue users encounter with Tekton is when a PipelineRun is unexpectedly skipped. This can be perplexing, especially when the pipeline is expected to execute as part of a CI/CD process.

What You Observe

In the Tekton dashboard or logs, you may notice that a particular PipelineRun has not executed. Instead, it is marked as skipped, and no further steps are taken.

Exploring the Issue: Why PipelineRun is Skipped

The primary reason a PipelineRun is skipped is due to unmet conditions or a failure in a previous run. Tekton allows for conditional execution of tasks, which means that if certain conditions are not met, the pipeline will not proceed.

Common Causes

Conditions specified in the pipeline are not satisfied. A previous task or pipeline run failed, causing subsequent runs to be skipped. Resource constraints or misconfigurations in the pipeline definition.

Steps to Fix the PipelineRun Skipped Issue

To resolve the issue of a skipped PipelineRun, follow these steps:

1. Review Pipeline Conditions

Check the conditions specified in your pipeline. Ensure that all conditions are correctly defined and that the expected inputs are available. You can review the pipeline definition in your YAML file:

kubectl get pipelinerun -o yaml

Look for any conditions that might not be met.

2. Check Previous PipelineRun Status

Investigate the status of previous PipelineRun executions. If a previous run failed, it might be causing the current run to be skipped. Use the following command to list previous runs:

kubectl get pipelineruns

Examine the logs of the failed runs to identify the root cause.

3. Validate Resource Availability

Ensure that all resources required by the pipeline are available and correctly configured. This includes checking for any missing or misconfigured secrets, config maps, or other dependencies.
