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

So, there is another reason! When you try to install r=Redash using the setup.sh from the Github, the script automatically gets the latest version of Redash and put it in docker-compose.yml. The base yml file doesn't have single-quotations (') around version name! As a result, you get an error that says:

ERROR: yaml.scanner.ScannerError: mapping values are not allowed here in "./docker-compose.yml", line 3, column 23 You just add single-quotation around the Redash version:

version: "2"
x-redash-service: &redash-service
  image: 'redash/redash:8.0.0.b32245'
