error at docker-compose up

ansible@ansible:~/diveintoansible-lab$ docker-compose up
ERROR: Version in "./docker-compose.yaml" 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.

Any idea what is wrong? I am new to docker.

Hi @ubergoonz

We’ll get this resolved. What distribution of Linux are you running and how did you install docker-compose, it looks to me like it’s the version of this that’s causing you the issue
