lex-node

Node identity and cluster management for LegionIO. Handles heartbeat broadcasting, cluster secret exchange, Vault token management, and RSA public key distribution between nodes.

This is a core LEX installed by default with LegionIO.

Installed automatically as a dependency of legionio. To disable:

• Beat - Periodic heartbeat broadcast to the cluster
• Crypt - RSA keypair exchange: distribute and receive public keys and cluster secrets
• Node - Dynamic configuration distribution across cluster nodes
• Vault - Vault token lifecycle: request, receive, and push Vault tokens between nodes

Each node periodically calls beat to broadcast its presence. On startup, nodes exchange RSA public keys, then use them to securely distribute the cluster shared secret (AES encryption key) and Vault tokens - all encrypted peer-to-peer so no secrets traverse the bus in plaintext.

• Ruby >= 3.4
• LegionIO framework
