detach

Starts a pipeline in the node.

pipeline::detach { … }, [id=string]

Description

The pipeline::detach operator starts a hidden managed pipeline in the node, and returns as soon as the pipeline has started.

Subject to Change

This operator primarily exists for testing purposes, where it is often required to run pipelines in the background, but to be able to wait until the pipeline has started. The operator may change without further notice.

id = string (optional)

Sets the pipeline's ID explicitly, instead of assigning a random ID. This corresponds to the id field in the output of pipeline::list, and the pipeline_id field in the output of metrics and diagnostics.

Examples

Run a pipeline in the background

pipeline::detach {
  every 1min {
    version
  }
  select version
  write_lines
  save_stdout
}
