Hello @dragonku7,

The first thing to check is whether you have the right docker engine installed. This table shows which compose files are compatible with the docker engine: https://docs.docker.com/compose/compose-file/#compose-and-docker-compatibility-matrix

This command should tell you which docker version you have:

docker version --format "{{.Client.Version}}"

You need docker version > 18.06.0+ for the compose file v3.7 to work.

Let me know if that helps.
