received the below

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. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

below is the docker compose.yaml

Hi @morothebest

This is an incorrect version of docker-compose. If you install via apt or yum, it is unfortunately an old version. Can you please grab a version from the releases section of the docker-compose github repo. This is what I do in the Linux setup video for reference.

Best Regards

James
