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

Ok, I wasted around 3 hours to debug a similar issue.

If you guys ever get the below error

ERROR: yaml.scanner.ScannerError: mapping values are not allowed here
in ".\docker-compose.yml", line 2, column 9

It's because a space is needed between

version:'3' <-- this is wrong

version: '3' <-- this is correct.

Also, if you are using eclipse, do yourself a favor and install the YEdit YAML editor plugin
