Replace the coturn image's fragile eval-based entrypoint with a robust wrapper that handles external IP detection without word-splitting issues. The image's `exec $(eval "echo $@")` produces empty tokens when DETECT_EXTERNAL_IP's DNS lookup fails → "ERROR: CONFIG: Unknown argument:" Also add --listening-ip=0.0.0.0 so coturn binds a single wildcard address instead of enumerating every host interface (reduces log noise). https://claude.ai/code/session_01KWVtEt9MmZdywcu7WmgchX

# Robust coturn entrypoint
|
|
#
|
|
# The coturn/coturn Docker image's native entrypoint uses:
|
|
# exec $(eval "echo $@")
|
|
# which is fragile — if DETECT_EXTERNAL_IP's DNS lookup returns empty,
|
|
# the eval produces an empty token → "ERROR: CONFIG: Unknown argument:"
|
|
#
|
|
# This wrapper reuses the image's detect-external-ip script but avoids
|
|
# the eval word-splitting issue. If detection fails, we simply omit
|
|
# --external-ip rather than passing a blank argument.
|
|
# ================================================================
|
|
|
|
# Use explicit PUBLIC_IP if provided, otherwise auto-detect
|
|
