# Takes an "<ip>:<port>" value (e.g. "127.0.0.1:9187"), or empty string to not expose.
#
# You likely don't need to do this. See `matrix_prometheus_postgres_exporter_metrics_proxying_enabled`.
#
# Official recommendations are to run this container with `--net=host`,
# but we don't do that, since it:
# - likely exposes the metrics web server way too publicly (before applying https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1008)
