Version in "./docker-compose.yml" is unsupported

I have the following docker-compose.yml file

services:
  containerA:
    healthcheck:
      test: "/build/docheck"
      interval: "10s"
    hostname: "containerA"
    container_name: "containerA"
    build:
      dockerfile: "Dockerfile-5.6"
    ports:
    - "8081:8081"
version: "2.1"

When I try the following command: docker-compose up

it fails due to:

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 version of "2" (or "2.0") 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/

I have the following setting:

$> docker-compose --version
docker-compose version 1.8.0, build unknown

$> docker --version
Docker version 17.12.0-ce, build c97c6d6

$> uname -r
4.9.0-4-amd64

$> lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 9.3 (stretch)
Release:    9.3
Codename:   stretch

I need to use version 2.1 because I am using the healthcheck. Any ideas why this is complaining?

Compose files Version 2.1 are supported by Docker Compose version 1.9.0+. And you have docker-compose version 1.8.0. To upgrade docker-compose you can run following commands:

If installed via apt-get:

sudo apt-get remove docker-compose

If installed via curl:

sudo rm /usr/local/bin/docker-compose

If installed via pip:

pip uninstall docker-compose

Then find the newest version on the release page at GitHub or by curling the API and extracting the version from the response using grep:

VERSION=$(curl --silent https://api.github.com/repos/docker/compose/releases/latest | grep -Po '"tag_name": "\K.*\d')

Finally, download to your $PATH-accessible location and set permissions:

DESTINATION=/usr/bin/docker-compose
sudo curl -L https://github.com/docker/compose/releases/download/${VERSION}/docker-compose-$(uname -s)-$(uname -m) -o $DESTINATION
sudo chmod 755 $DESTINATION

Installation of a new version of Docker Compose helped me to fix this error. See official documentation.

I was getting this error when I was trying the command docker-compose up with the docker compose version 3. Then I run the command to check the docker version docker version, which result the below output. 

PS C:\SVenu\M4Movie\Api\Api> docker version
Client:
 Version:      18.03.1-ce
 API version:  1.37
 Go version:   go1.9.5
 Git commit:   9ee9f40
 Built:        Thu Apr 26 07:12:48 2018
 OS/Arch:      windows/amd64
 Experimental: false
 Orchestrator: swarm

So my version is 18.03, which is the latest one for now. So I moved to this link to check the compose file version which supports this engine. Then changed my docker compose version to 3.6.

version: '3.6'

Everything was working fine after that.

adding this because i ran into the same error on Ubuntu.

For me, it had nothing to do with my Compose version despite what the error message says; i just had to run with sudo. so

sudo docker-compose up

Following the link to details about versions, you'll find:

Version 2.1

An upgrade of version 2 that introduces new parameters only available with Docker Engine version 1.12.0+. Version 2.1 files are supported by Compose 1.9.0+.

https://docs.docker.com/compose/compose-file/compose-versioning/#version-21

You'll need to upgrade your docker-compose install to support the 2.1 file version. https://docs.docker.com/compose/install/
