docker-compose up -d
ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.

docker-compose --version
docker-compose version 1.25.0, build unknown

I followed the instructions here: https://docs.docker.com/engine/install/debian/ to install docker.

[Zoey2936]

Maybe try it with docker-compose v2 And just a small note, 8081:8081 should be 8081:8080, since the first number is the external port and 8080 the internal port

I have another docker thingy running on 8080

[Zoey2936]

Yes, but the first port is the port where it will be reachable, and the second is the port internally of the docker container, you could have 100 containers with the same internal port, as long the external port is different

ah, I see, that makes sense

Ok, I think your docker version would be the most interesting, because of this: https://docs.docker.com/compose/compose-file/compose-file-v3
