Zebra already exposes /ready and /healthy endpoints on port 8080. It might be better to leverage Docker's native health orchestration instead of the curl; similar to how we do in the Z3 stack:

zebra:
  healthcheck:
    test: ["CMD-SHELL", "curl -sf http://127.0.0.1:8080/healthy || exit 1"]
    interval: 30s
    timeout: 10s
    retries: 3
    start_period: 90s

Then s-nomp can rely on Docker to handle the wait:

s-nomp:
  depends_on:
    zebra:
      condition: service_healthy

I know this is confirming the RPC instead, but the overall goal is similar.

I think this should be an actual script file (e.g., docker/mining/s-nomp-entrypoint.sh) rather than inline YAML. A script file could be linted, tested, and versioned more cleanly.

Nit:nheqminer already uses profiles: [miner]. A consideration (doesn't need to be this PR): redis and s-nomp could also be placed behind a profiles: [mining] in the main docker/docker-compose.yml, rather than living in a separate docker/mining/ directory with its own compose file.

This would allow composing capabilities from a single file:

# Just Zebra
docker compose up -d

# Zebra + mining pool
docker compose --profile mining up -d

# Zebra + mining pool + CPU miner
docker compose --profile mining --profile miner up -d

# Zebra + observability
docker compose --profile monitoring up -d

# Everything
docker compose --profile mining --profile miner --profile monitoring up -d

This is the pattern used in Z3 for the monitoring stack and avoids duplicating the zebra service definition across multiple compose files.

Not blocking for this PR; just flagging the direction in case we'd like to start consolidating the Docker compose
