feat: add AUTOBAHN option to local docker cluster (CON-247) by wen-coding · Pull Request #3220 · sei-protocol/sei-chain

wen-coding · 2026-04-09T16:00:12Z

Summary

Add AUTOBAHN=true option to local docker cluster for testing autobahn consensus
NodeKey.SaveAs() writes node_pubkey.txt alongside node_key.json (node:ed25519:public:<hex> format)
FilePVKey.Save() writes validator_pubkey.txt alongside priv_validator_key.json (validator:ed25519:public:<hex> format)
step1_configure_init.sh copies pubkey files to shared volume for cross-node access
seid tendermint gen-autobahn-config Go command reads all nodes' pubkeys and generates the autobahn JSON config with typed validation (atypes.PublicKey, p2p.NodePublicKey, tcp.HostPort)
step4_config_override.sh invokes the command and injects the config path into config.toml
Shared AutobahnFileConfig and AutobahnValidator types in sei-tendermint/config/autobahn.go, used by both node/setup.go and the gen command
Startup log messages: "Autobahn config enabled", "Autobahn config loaded", "GigaRouter initialized"
AUTOBAHN env var wired through docker-compose.yml and Makefile

Usage

AUTOBAHN=true make docker-cluster-start

Test plan

AUTOBAHN=true make docker-cluster-start — all 4 nodes start with autobahn enabled, logs show config loaded and GigaRouter initialized
make docker-cluster-start (without AUTOBAHN) — no autobahn messages in logs, nodes start normally
go build ./... passes
gofmt -s -l . clean
Existing tests pass (config, node, commands, server packages)

+		return err
+	}
+	// Write pubkey in autobahn-compatible format alongside the key file.
+	pubKeyStr := fmt.Sprintf("node:%v", nk.PubKey().String())


Suggested change

pubKeyStr := fmt.Sprintf("node:%v", nk.PubKey().String())

pubKeyStr := fmt.Sprintf("node:%s", nk.PubKey().String())

nit: ".String()" suffix is redundant (if we used %v)

also it is unfortunate that we need to duplicate Stringer implementation here. At least add a todo to fix that.

done and added TODO

Ditto re path cleaning.

+		return err
+	}
+	// Write pubkey in autobahn-compatible format alongside the key file.
+	pubKeyStr := fmt.Sprintf("validator:%v", pvKey.PubKey.String())


ditto re %s for string concat; that's more explicit given we want the strigner value of key and would safely fail if anything but string is passed in.

docker/localnode/scripts/step4_config_override.sh

+  AUTOBAHN_CONFIG="$HOME/.sei/config/autobahn.json"
+
+  # Build validators JSON array from all nodes' pubkeys
+  VALIDATORS="["


nit: do we really need this to be a bash script? My guess is that given that we use go binary to generate these files, we could also use a go binary to combine them into a full config.

That's actually a good point, I reworked it to call seid tendermint gen-autobahn-config and moved the Autobahn config definitions around, ready for another look.

wen-coding · 2026-04-10T16:11:53Z

@masih @pompon0 changed the PR significantly to share AutobahnConfig definition between generation and loading, and moved AutobahnConfig generation into a go file to be called by seid tendermint gen-autobahn-config, please take another look.
