Compose: Unsupported config option 'healthcheck' with version 2.1 syntax

[bperel]

Using the following docker-compose.yml:

version: '2.1'
services:
  db:
    image: "<my_image>"
    healthcheck:
      disable: true

I get the following error when running docker-compose up :

$ docker-compose up
ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.db: 'healthcheck'

According to the documentation, "healthcheck" should be supported with the currently installed versions:

$ docker --version
Docker version 1.13.0, build 49bf474

$ docker-compose --version
docker-compose version 1.9.0, build 2585387

Hi,

you have to upgrade to Compose 1.10.1 - 1.9 doesn't have healthcheck support.

The documentation didn't make it clear: it just specifies that Compose 1.6.0 is required for version 2.0 of the docker-compose.yml specification. Maybe a documentation update would help other people as well :-)

You can also see this error if healthchecks are defined in your yaml file but the 'version' value in the file is '2' (for example) even if you are running a docker compose version that supports them. Change the version in the file to the correct version (such as 2.3) may be the only needed remedy in that case.
