Run the docker-build assembly in .gitlab-ci.yml

Question

I have one .gitlab-ci.ymlthat contains the following:

image: docker:latest

services:
  - docker:dind

before_script:
  - docker info
  - docker-compose --version

buildJob:
  stage: build
  tags:
    - docker
  script:
    - docker-compose build

But in ci-logI get the message:

$ docker-compose --version
/bin/sh: eval: line 46: docker-compose: not found

What am I doing wrong?

Answer 1

EDIT I added another answer providing a minimal example configuration .gitlab-ci.yml that supports docker layout.

docker-composecan be installed as a Python package that does not come with your image. The selected image does not even provide Python installation:

$ docker run --rm -it docker sh
/ # find / -iname "python"
/ #
