-# Docker compose file to simulate a sentry node setup.
-#
-#
-# Setup:
-#
-# Validator A is not supposed to be connected to the public internet. Instead it
-# connects to a sentry node (sentry-a) which connects to the public internet.
-#
-#
-# Usage:
-#
-# 1. Build `target/release/substrate` binary: `cargo build --release`
-#
-# 2. Start networks and containers: `sudo docker-compose -f scripts/sentry-node/docker-compose.yml up`
-#
-# 3. Reach:
-#   - validator-a: localhost:9944
-#   - sentry-a: localhost:9946
