Docker无法在gitlab Runner中运行，可能是什么问题？

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"

Answer 1

You can verify these 3 steps:

1. Is Docker Engine installed on server
2. Is the gitlab-runner user added to docker group
3. Has the gitlab-runner access to Docker

Follow the official page for more information: https://docs.gitlab.com/ee/ci/docker/using_docker_build.html

Answer 2

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"
