Compose: Compose file version 3.2 is unsupported - v1.12.0-rc2

[andrewmilson]

I'm trying to use the new Compose long syntax ports

version: '3.2'
...
    ports:
      - target: 50020
        published: 50020
        protocol: tcp
        mode: host
      - target: 50010
        published: 50010
        protocol: tcp
        mode: host
...

Getting following error on docker-compose build

ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version ("2.0", "2.1", "3.0", "3.1") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

@shin- Known?

Thanks for the report, I'll look into it ASAP.

@shin- Was this fixed in 1.12.0? I am getting this same error:

Unsupported Compose file version: 3.2
$ docker-compose -v
docker-compose version 1.12.0, build b31ff33

@robvelor It was. What command are you running?

[robvelor]

@shin- docker stack deploy --compose-file $compose_file --with-registry-auth $ENVIRONMENT

Yeah, you're not using docker-compose, you're using the engine - that's the part that you need to upgrade. 17.04.0-ce is the version that introduced support for v3.2

My bad, my client is at 17.03.0-ce, build 60ccb22 that explains it. Thx.
