I think you are going to need a "restart: always" in each service section so that everything will start on reboot?

Thanks for writing this docker-compose.yml file. I believe the volume mount for 'validator' container should be

    volumes:
    - "${HOME}/validator_data:/var/data"

@philltran removing a trailing slash? It should work either way.

You are right. The issue I was having was with the quay tag. I needed to use validator for the main net and not val for testnet.

good call! I was having trouble mentally diffing it.

@tedder Don't you need a "restart: always" in each service section so that everything will start on reboot?

@jkowalcz not a bad idea. added.

Might want to add 8080 port for light hotspots

https://gist.github.com/rootulp/4fe3a7e420237a5632f3201faa246ab4 has two editions to this docker-compose.yml

1. Expose 8080 per deployment guide
2. Increase ulimits to avoid No file descriptors available error
