Logging was configured correctly and shipping to Loki, but the stream was useless: measured at 100% healthcheck chatter, with every line wrapped in ANSI escape codes. The real SIP events were there and completely buried. Three causes, each masking the next: - asterisk.conf was written in the first lab commit with `nocolor = yes` and never mounted, so the setting had no effect. Now mounted. It was also overriding [directories] and runuser/rungroup, which the image sets up correctly itself — removed, since overriding them risks breaking the container for no gain. - The image's command is `-vvvdddf`: verbosity 3 and debug 3 forced on the command line, which overrides both asterisk.conf and logger.conf. Overridden in compose to drop -v and -d; warnings and errors still log, and verbosity is raisable at runtime when tracing a call. - The actual source: the image's healthcheck makes ~7 separate `asterisk -rx` connections every 30s, and Asterisk logs a connect/disconnect pair for each. Replaced with a single check on a 60s interval, and the check now runs `pjsip show transports` rather than `core show version` — that fails when Asterisk is up but unconfigured, which is exactly the state that produced a "healthy" container with no SIP stack on first deploy. logger.conf drops both `notice` and `verbose`, which is where those pairs arrive. Verified on galatea: noise down from ~48 to 8 lines per two minutes (-83%), zero ANSI codes in Loki, 90% of the stream now signal, container still healthy, transport and dialplan intact.

# This is the LOCAL variant: ports and credentials are concrete, not Jinja.

# CLI: docker compose -f docker-compose.lab.yml exec asterisk asterisk -rvvv

|
# host networking: SIP/RTP carry IP addresses *inside* the payload, so a
|
|
# bridged network needs external_media_address set correctly or the call
|
|
# connects with no audio. Host networking sidesteps that entirely for local
|
|
# work. The Virgo deploy uses the same approach for the same reason.
