How to integrate Cross with Gitlab CI?

[hanusek]

Hello.
I use docker runner in Gitlab CI. I would like to use Cross in CI.
How do it?

See #273 and https://github.com/cross-rs/cross/wiki/FAQ#gitlab-ci

Is it possible that the linked FAQ is out of date?

i always get

Error:
0: no container engine found

here my gitlab ci conf

image: "rust:latest"
build:raspy:cfw:
  stage: build
  variables:
    DOCKER_HOST: tcp://docker:2375/
    DOCKER_DRIVER: overlay2
    CROSS_REMOTE: 1

    DOCKER_TLS_CERTDIR: ""
    FF_NETWORK_PER_BUILD: "true" # doesnt matter if i add this or not
  services:
    - docker:18.09-dind # doesnt matter if i use latest version or 18.09
  before_script:
    - cargo install cross

  script:
    - cross build

or do i need to run a different image? (one that replaces cross with some wrapper script?)
