PipelineRun status

Status #

GitHub apps #

After the PipelineRun has finished, its status will be shown in the GitHub Check tabs, along with a concise overview of the status the name and the duration of each task in the pipeline. If the task has a displayName it will use it as the description of the task or otherwise just the task name.

If any step fails, a small portion of the log from that step will also be included in the output.

In case an error is encountered while creating the PipelineRun on the cluster, the error message reported by the Pipeline Controller will be conveyed to the GitHub user interface. This facilitates the user to swiftly identify and troubleshoot the issue, without having to navigate to the underlying infrastructure.

Any other error that may arise during the execution of the pipeline will also be reported to the GitHub user interface. However, if there was no match for the namespace, the error will be logged in the Pipelines-as-Code Controller’s logs.

Statuses for other providers (Webhook based) #

If the webhook event pertains to a pull request, it will be included as a comment to the corresponding pull or merge request. However, when it comes to push events, it is not feasible to exhibit the status of the PipelineRun as there is no dedicated space to showcase it. In such scenarios, you can employ alternate methods as enumerated below.

Log Snippet when reporting error #

If an error is detected in one of the tasks in the Pipeline, a brief excerpt of the last three lines from the task breakdown is displayed. However, the API has a character limit that restricts us to output only the output of the first failed task.

To prevent exposing secrets, Pipelines-as-Code analyze the PipelineRun and replace secret values with hidden characters. This is achieved by retrieving all secrets from the environment variables associated with tasks and steps, and searching for matches of these values in the output snippet. These matches are then replaced with a "*****" placeholder hidding these secrets.

The hiding of the secret does not support concealing secrets from workspaces and envFrom sources.

Error detection from containers logs as GitHub Annotation #

If you enable the error-detection-from-container-logs option in the pipeline-as-code configuration map, Pipelines-as-Code will attempt to detect errors from the container logs and add them as annotations on the corresponding Pull Request where the error occurred.

Currently, only a simple error format such as those resembling makefile or grep output are supported, specifically the format of :

filename:line:column: error message

Tools like golangci-lint, pylint, yamllint, and many others can produce errors in this format.

You can refer to the Pipelines-as-Code pull_request.yaml for an example of how we lint our code and output errors in the specified format.

You can customize the regular expression used for detecting errors with the error-detection-simple-regexp setting. The regular expression uses named groups to provide flexibility in specifying the matching criteria. The necessary groups for matching are filename, line, and error (the column group is not used). The default regular expression is defined in the configuration map.

By default, Pipelines-as-Code searches for errors in only the last 50 lines of the container logs. However, you can increase this limit by setting the error-detection-max-number-of-lines value. If you set this value to -1, the system will search through all available lines for errors. Keep in mind that increasing this maximum number of lines may increase the memory usage of the watcher.


Namespace Event stream #

When a namespace has been matched to a repository, Pipelines-as-Code will emit its log messages as Kubernetes events within the namespace of the corresponding repository.

Repository CRD #

The most recent five statuses of any PipelineRuns associated with a repository are stored within the corresponding repository custom resource (CR).

% kubectl get repo -n pipelines-as-code-ci
NAME                  URL                                                        NAMESPACE             SUCCEEDED   REASON      STARTTIME   COMPLETIONTIME
pipelines-as-code-ci   https://github.com/openshift-pipelines/pipelines-as-code   pipelines-as-code-ci   True        Succeeded   59m         56m

Using the tkn pac describe command from the cli you can easily view all of the statuses of the PipelineRuns associated with your repository, as well as their metadata.

Notifications #

Notifications are not managed by Pipelines-as-Code.

To add notifications to your pipeline runs, you can use the finally feature of Tekton Pipelines. This allows you to execute a set of tasks at the end of a pipeline run, regardless of whether it succeeds or fails.

Here is an example of a task sending a Slack message on failures or successes:


As an example, you can refer to the push pipeline in the Pipelines-as-Code repository, which sends a Slack message if there are any failures while generating artifacts on every push. The relevant section of the pipeline can be found here:
