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

I wanted a volume mapped to a specific path on the external (host) server. I tried putting that under the top-level volumes entry in docker-compose.yml. After looking at the docker-compose file docs, I realized that that type of volume does not go there. Instead, it goes only under the volumes entry within the container definition. E.g.:

version: "3.7"
services:
  web:
    image: my_custom_web_image
    build: ./app
    volumes:
      - ./app/subdir:/usr/src/app/subdir
