Major Description
The errors are as follows, and the scale specification keyword is deprecated[1], and it suggest using replicas[2], so I think we should change it.
BTW, from [3] we see the following discuss：
"scale is not supported in v3 compose format. Try to set your compose file version to "2.4" or "2.2". If you really want to use the v3 format, try to set deploy.replicas instead as in https://docs.docker.com/compose/compose-file/#deploy."
