v1.2.13: compose: forward SUBTENSOR_CHAIN_ENDPOINT to the validator (#274)
About SN15 ORO
compose: forward SUBTENSOR_CHAIN_ENDPOINT to the validator An external validator (Nikolay, Staked) got stuck on foundation-finney 429s during weight setting because the compose stack has no passthrough for SUBTENSOR_CHAIN_ENDPOINT — even if a validator sets it in .env to point at their own subtensor RPC, the container never sees it and bittensor resolves SUBTENSOR_NETWORK=finney to the shared public endpoint. The problem is louder since async-substrate-interface 2.x (#228 SDK bump) reconnects more aggressively. Forward SUBTENSOR_CHAIN_ENDPOINT in the validator service's env. Rewrite command: under sh -c so ${VAR:+…} interpolation can omit --subtensor.chain_endpoint entirely when the env var is unset. Empty flag isn't equivalent to "resolve from network" — bittensor rejects it. Document the var in .env.example with an example wss URL + why private RPC is the practical answer. Co-Authored-By: Claude Opus 4.7 [email protected] Read SUBTENSOR_CHAIN_ENDPOINT in main.py; keep compose command clean Cleaner alternative to the sh -c wrapper: read SUBTENSOR_CHAIN_ENDPOINT inside get_config() the same way SANDBOX_MAX_WORKERS and friends are already read, and inject --subtensor.chain_endpoint <url> into sys.argv before argparse runs. Compose's command: block goes back to the clean YAML list form. Why the env-read: bittensor's --subtensor.chain_endpoint has no env-var default, and passing the flag with an empty value routes to ("unknown", "") in determine_chain_endpoint_and_network and crashes on connect. So we can't just interpolate ${VAR:-} in the command list the way SUBTENSOR_NETWORK does. Co-Authored-By: Claude Opus 4.7 [email protected] Co-authored-by: Claude Opus 4.7 [email protected]
