# smpp-dumb-client is one-shot and dials out, so it needs node:2775 already listening - the same
# problem compose.smppload.yaml's entrypoint solves, and the same fix: a healthcheck this marker
# satisfies at once, and node depends on it rather than the other way round.
#
# Its own smpp.remote config field is fed straight into net.ParseIP with no DNS resolution at all
# (hdr.go), so the compose service name in every conf/*.yml is a NODE_HOST placeholder, resolved
# here and substituted into a writable copy before the real binary ever sees the config file.
