when i run docker-composer up it shows ERROR: Version "1.0" in ".\\docker-compose.yml" is invalid. I am not finding why this error

Answer 1

There are three major versions of the docker-compose.yml file itself . You typically want the latest one

version: '3.7'

Version 1 was significant different from its successors: it put all of the service definitions at the top level, and didn't support top-level version: or services: keys. There are a number of other changes as well; if you need custom network configuration, Swarm support, or to specify the image name of a locally-built image, version 1 doesn't have any of these things.
