Configurator

Generates genesis files, node configuration, topology, and signing keys for the testnet at startup.

How it works

1. Reads testnet.yaml for genesis parameters (pool count, network magic, epoch length, protocol version)
2. Runs the testnet-generation-tool to produce genesis files and pool keys
3. Generates a ring topology for producers (p1↔p2↔p3)
4. Sets the system start time to the current time
5. Writes configs to per-pool volumes (p1-configs, p2-configs, p3-configs)

Image

ghcr.io/cardano-foundation/cardano-node-antithesis/configurator:<commit>

Built from components/configurator/Dockerfile. Uses cardano-cli and cardano-node from the official IntersectMBO image (pinned to the highest node version in the testnet).

Key files

• configurator.sh: Main entry point — orchestrates genesis generation, topology, and config post-processing
• Dockerfile: Multi-stage build copying cardano binaries + Nix deps from the official node image

Outputs

Each pool volume receives: - configs/config.json — node configuration - configs/topology.json — peer connections - configs/*-genesis.json — Byron, Shelley, Alonzo, Conway genesis files - keys/ — pool-specific signing keys (KES, VRF, opcert, payment, stake)
