suspend-template-outputs.yaml

# This example uses a suspend template that expects outputs to be provided to it. These outputs may be provided by the CLI
# with the 'argo node set' command, the API with the '/set' endpoint, or directly via K8s.
#
# Example:
#   argo node set suspend-outputs -p message="Hello, world!" --node-field-selector displayName=approve
#   argo node set suspend-outputs --message="Test message" --node-field-selector displayName=approve
#   argo resume suspend-outputs
