Minimal needed files to run a hedera mirror node and relay services
docker-compose.yml file - with all the services :
- hedera stack (from: https://github.com/hashgraph/hedera-mirror-node.git)
- traefik and nginx (choose your poison, both work)
for the hedera stack (in order to sync) - you need to complete the application.yml file with your api keys (be it GCP or AWS).
.env.example file for the relay stack - do a cp .env.example .env and set the vars. These are minimal/mandatory.

obviously, you need to fund the wallet with some HBAR
