# Controls whether the matrix-prometheus container exposes its HTTP port (tcp/9100 in the container).
#
# Takes an "<ip>:<port>" value (e.g. "127.0.0.1:9100"), or empty string to not expose.
#
# 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)
# - or listens on a loopback interface only (--net=host and 127.0.0.1:9100), which is not reachable from another container (like `matrix-prometheus`)
#
# Using `--net=host` and binding to Docker's `matrix` bridge network may be a solution to both,
# but that's trickier to accomplish and won't necessarily work (hasn't been tested).
#
# Not using `--net=host` means that our network statistic reports are likely broken (inaccurate),
# because node-exporter can't see all interfaces, etc.
# For now, we'll live with that, until someone develops a better solution.
