docker-compose-atomizer.yml

in this file

watchtower0: build: context: . target: atomizer image: opencbdc-tx-atomizer tty: true command: ./build/src/uhs/atomizer/watchtower/watchtowerd atomizer-compose.cfg 0 ports:

why port is 8555:8555 but expose 8556?

is this right?

HalosGhost commented 8 months ago

ports and expose are separate sections in docker-compose, and though they work similarly (both make ports available to other services outside the container but connected to the same network), but expose doesn't publish the port to the host (they are only available to linked services). In short, this configuration binds 8555 to the host's 8555 and exposes 8556 to linked services (but not to the host).

Does that make more sense?

I'm going to close this for now; if you find you have more questions or need additional clarification, please feel free to comment and we can reopen if that makes sense!
