Docker not working in gitlab runner, what could be the problem?

Question

When I try to run my gitlab-ci.yml, I get the following error:

/bin/bash: line 73: docker: command not found

On my server the docker command works as root and gitlab is also executing as root.

What could be the problem here?

Here is my .yml file:

stages:
  - deploy
  - cleanup

before_script:
  - whoami
  - docker login -u "gitlab-ci-token" -p "$CI_BUILD_TOKEN" "$CI_REGISTRY"

I followed this tutorial: https://docs.gitlab.com/runner/install/linux-manually.html — user9468014, Jan 25 '19 at 12:52
Its about installation, but what type did you choose? Shell executor, docker or etc? — grapes, Jan 25 '19 at 12:57
If you dont know, it could be difficult for you to setup `docker-in-docker` because it requires more deep understanding of setup process — grapes, Jan 25 '19 at 12:58
Take a look at my answer if you want to use Docker executor. https://stackoverflow.com/a/50684269/7786148 — gcharbon, Jan 26 '19 at 14:38

Your gitlab-ci.yml looks incomplete. Try something like this:

stages:
  - build

build-docker:
  stage: build
  script:
     - whoami
     - docker login -u "gitlab-ci-token" -p "$CI_BUILD_TOKEN" "$CI_REGISTRY"

Sorry for the misunderstanding I have more stages after the before_script – user9468014 Jan 25 '19 at 13:03
just copied this since it fails there – user9468014 Jan 25 '19 at 13:03
Ok well whats the output of your `whoami` command? Chances are that user can't see the docker executable. – Matthew Jan 25 '19 at 13:10
the output is root. Thanks for your help I'm trying everything now but I'm somehow stuck – user9468014 Jan 25 '19 at 13:16
