Tekton target

Sends events to Tekton to create Tekton TaskRun or PipelineRun objects.

With tmctl:

tmctl create target tekton

On Kubernetes:

kind: TektonTarget
  name: triggermesh-tekton-target
    success: 5m  # clean up all successfully completed task runs
    fail: 1h  # clean up all failed task runs

Tekton Target accepts events of type io.triggermesh.targets.tekton, which create a new Tekton PipelineRun or TaskRun object.

This type expects a JSON payload with the following properties:

Name Type Comment
buildType string The run object type consisting of task or pipeline
name string The Tekton task or pipeline object to invoke
params map[string]string Dictionary mapping of parameters to pass to the Tekton task or pipeline

No response events are created with this Target type.

NOTE: On Kubernetes, neither of TaskRun and PipelineRun objects nor their associated pods are deleted after execution. It is up to the user to perform the clean-up.

Reaping prior Tekton TaskRuns and PipelineRuns

To allow for reaping of old run objects, the TektonTarget Spec supports defining a duration interval (in the form of \d+[mhd] for minute, hour, or day) for how long to keep the run objects before purging.

  • reapPolicy.success Age of run objects to keep that succeeded
  • Age of the run objects to keep that failed

To trigger the reaping, a CloudEvent type of io.triggermesh.tekton.reap must be sent to the target.

You can test the Target by sending it an event using curl:

curl -v http://tektontarget-helloworld5d0adf0209a48c23fa958aa1b8ecf0b.default.svc.cluster.local \
 -X POST \
 -H "Content-Type: application/json" \
 -H "Ce-Specversion: 1.0" \
 -H "Ce-Type:" \
 -H "Ce-Source: awesome/instance" \
 -H "Ce-Id: 536808d3-88be-4077-9d7a-a3f162705f79" \
 -d '{"buildtype": "task","name": "tekton-test","params":{"greeting":"Hi from TriggerMesh"}}'

See the Kubernetes object reference for more details.
