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

Also make sure you have context and dockerfile at the same identation. I made a mistake and was stuck for hours.

My error was

ERROR: yaml.scanner.ScannerError: mapping values are not allowed here in "./docker-compose.yml", line 6, column 19

Wrong:

version : '3'
services:
  test:
    build:
      context: ./test
        dockerfile: Dockerfile.test
    image: kpod/test:2020

Right:

version : '3'
services:
  test:
    build:
      context: ./test
      dockerfile: Dockerfile.test
    image: kpod/test:2020
