# Container-appropriate defaults. The image bakes this at
# /etc/dnsink/config.toml; override with a bind-mount to customize:
#
#   docker run -v /path/to/my-config.toml:/etc/dnsink/config.toml:ro ...

[listen]
# fly.io needs asymmetric binding:
#   UDP must bind to fly-global-services so Linux uses the right source
#   IP on replies (wildcard binds break UDP on fly).
#   TCP must bind to a wildcard so fly-proxy's external route-in lands.
# `tcp_address` overrides the UDP bind address for TCP specifically.
# 5353 avoids NET_BIND_SERVICE on the distroless nonroot user.
# For local Docker runs (no fly-global-services), users override the
# config via `-v` bind-mount.
