use_container_labels and container_name, container_id, conta

Error message

use_container_labels and container_name, container_id, container_id_regexp, container_name_regexp are mutually exclusive

What it means

Validation guard in docker UnmarshalConfig: use_container_labels is enabled while explicit container selectors (container_name, container_id, container_id_regexp, container_name_regexp) are also set. Label-based discovery and explicit selection are mutually exclusive strategies; allowing both would make the watched set ambiguous.

Solutions

1. Either set use_container_labels: true and remove all container_* selectors, or disable it and list containers explicitly
2. Pick discovery-by-label when containers are ephemeral; pick explicit selectors for stable setups
