How to fix docker-compose.yaml error ?

[Dan1ell]

Hi community,

I'm receiving the following error while installing mediacms:

dan1ell@dan1ell:~/mediacms$ docker-compose build && docker-compose up
ERROR: The Compose file './docker-compose.yaml' is invalid because:
services.web.build contains unsupported option: 'target'
services.migrations.depends_on contains an invalid type, it should be an array

I can see the 2 offending lines in the yaml file, but I'm not sure what to change them into.

services:
  migrations:
    image: mediacms:latest
    volumes:
      - ./:/home/mediacms.io/mediacms/
    environment:
      ENABLE_UWSGI: 'no'
      ENABLE_NGINX: 'no'
      ENABLE_CELERY_SHORT: 'no'
      ENABLE_CELERY_LONG: 'no'
      ENABLE_CELERY_BEAT: 'no'
    depends_on:
      redis:
        condition: service_healthy
      db:
        condition: service_healthy
  web:
    build:
      context: .
      target: runtime-image
    image: mediacms:latest

Running Docker 19.03.8 on Ubuntu 20.04 in VirtualBox 6.1.18 r142142 on a Mac 11.2.1
What should I do here?

What version of Docker Compose you use? You might need to update to a newer one, eg 1.27.4 since the documentation suggests that this version was used (https://github.com/mediacms-io/mediacms/blob/main/docs/Docker_deployment.md)

This should fix the first line (services.web.build contains unsupported option: 'target') - docker/compose#5714

services.web.build contains unsupported option: 'target'

Yes, this is a docker-compose version issue: See:
docker/compose#5714

Thanks for your replies!
Changing the version number in the yaml file fixed the first error and updating docker-compose to a new version solved the second one.
Thanks!
