Spec #

This is a top-level attribute of the pipeline spec.

{
    "pipeline": {...},
    "transform": {...},
    "metadata": {
        "annotations": {
            "annotation": string
        },
        "labels": {
            "label": string
        }
    },
    ...
}

Behavior #

• Labels help organize and track cluster objects by creating groups of pods based on a given dimension.

• Annotations enable you to specify any arbitrary metadata.

Both parameters require a key-value pair. Do not confuse this parameter with podPatch, which adds metadata to the user container of the pipeline pod. For more information, see Labels and Selectors and Kubernetes Annotations in the Kubernetes documentation.

When to Use #

Use metadata for operation ergonomics and to simplify the querying of Kubernetes objects.
