Docker: Version "4.7.0" in ".\docker-compose.yml" is invalid-CodePudding

Since Docker has put up the new update for 4.7.0, I am getting the error above. This is my docker-compose.yml:

version: "20.10.14"

services:
  postgres:
    environment:
      POSTGRES_PASSWORD: xxxx
      POSTGRES_DB: marketplace
      POSTGRES_USER: postgres
    build:
      dockerfile: ./dbdockerfile/Dockerfile
  football_marketplace:
    build:
      dockerfile: Dockerfile
    ports:
      - 3300:3300
    depends_on:
      - "postgres"
  reactjs:
    build:
      dockerfile: ./football_marketplace-app/frontend/Dockerfile
    ports:
      - 3000:3000

I updated docker to 4.7.0 and tried multiple version numbers as a subsitute. I tried 20.10.14, which is the client version. Ive tried 4.7.0 and a couple other numbers.

This is my docker version output:

I have read other threads on here about this error but most suggest something that went wrong with docker-compose.override.yml which I don't use at all. Or that the docker version doesn't match the version number in the docker-compose.yml, but mine does.

CodePudding user response：

The version in the compose file is 2.x, 3.x, or in the latest compose-spec, removed completely:

https://docs.docker.com/compose/compose-file/#version-top-level-element

If you want to support legacy environments (many of them will still exist since compose-spec is relatively new), then use 2.4 which was the latest 2.x. The 3.x versions were focused on Swarm Mode support and removed some features like build and depends_on that do not work in Swarm Mode.
