Docker Compose Snark Workers

This example demonstrates how to run a Mina Snark Coordinator and a Snark Worker using Docker Compose for the Devnet network. The Docker Compose setup includes a Mina Snark Coordinator node, a Snark Worker node, a script to generate a libp2p key, and another script to generate a wallet key.

Copy and paste the provided configuration into a docker-compose.yml file. Then run docker compose up -d to start the services, and use docker compose logs -f to monitor the logs.
