Docker-Compose file has yaml.scanner.ScannerError

Question

compose.yml file, which looks like this:

version: \'2\'
services:
  discovery-microservice:
    build: discovery-microservice
      context: /discov         


        

Answer 1

Hi further update to the given answer .... It's not specifically about the version: '2.0' line The statement

ERROR: yaml.scanner.ScannerError: mapping values are not allowed here

means there's a formatting error of some sort.

I got it and it was because I was missing a tab in my docker-compose file

version: '3.0'
services:
  mysql:
  image: ...

instead of

version: '3.0'
services:
  mysql:
    image: ...

Note the lack of an indenting tab on the image line
