gitlab - 在 GitLab CI 管道中使用 docker-compose

Question

我正在尝试使用以下 .gitlab-ci.yml 实现 GitLab 持续集成 (CI) 管道文件:

image: docker:latest

# When using dind, it's wise to use the overlayfs driver for
# improved performance.
variables:
  DOCKER_DRIVER: overlay

services:
  - docker:dind

before_script:
  - docker info
  - curl -L "https://github.com/docker/compose/releases/download/1.10.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  - chmod +x /usr/local/bin/docker-compose
  - export PATH=/usr/local/bin:$PATH
  - echo $PATH

stages:
  - build
  - test

build:
  stage: build
  script:
    - docker-compose build
    - docker-compose up -d

test:
  stage: test
  script:
    - cd tests/tester
    - pytest test_run_tester.py
  except:
    - /^.*skip_tests$/

但是，在 GitLab 中，我收到以下错误消息:

系统好像找不到 docker-compose ，即使在安装它并将其添加到路径之后。是否还有其他图像，例如 docker-compose可以制作命令，或者在 .gitlab-ci.yml 中以不同的方式安装它。 ?

Answer 1

Docker-compose 现在是 official image .你可以把

image: 
  name: docker/compose:1.23.2
  entrypoint: [""]

在您的 .gitlab-ci.yml 顶部.您需要删除撰写图像的默认入口点，这是由第二行完成的。之后，您可以同时使用 docker和 docker-compose .
这适用于 GitLab 9.4。您还可以构建自定义图像

FROM docker/compose:1.23.2
ENTRYPOINT []

并将其用作您的图像。
