My apologies in advance, but I'm not a Docker expert. But following the outline in this project's readme doesn't result in a running service for me right now.

When running docker-compose up, I get the following output with an error:

$ docker-compose up -d
WARNING: The following deploy sub-keys are not supported and have been ignored: update_config, restart_policy.delay

It seems to be complaining that 0.0.0.0:8080 is already being used, but I used a TCP port viewer and that doesn't seem to be the case on my computer.

i get this error ,i don't what's wrong
