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 pod_patch, 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.
