docker - 在 .gitlab-ci.yml 中运行 docker-compose build

Question

我有一个 .gitlab-ci.yml 文件，其中包含以下内容:

image: docker:latest

services:
  - docker:dind

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

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

但在 ci-log 我收到消息:

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

我做错了什么？

Answer 1

Docker 还提供了一个官方镜像:docker/compose

如果您不想在每条管道上都安装它，这是理想的解决方案。

请注意，在最新版本的 GitLab CI/Docker 中，您可能需要授予对 GitLab CI Runner 的特权访问权限并配置/禁用 TLS。见 Use docker-in-docker workflow with Docker executor

variables:
  DOCKER_HOST: tcp://docker:2375/
  DOCKER_DRIVER: overlay2

# Official docker compose image.
image:
  name: docker/compose:latest

services:
  - docker:dind

before_script:
  - docker version
  - docker-compose version

build:
  stage: build
  script:
    - docker-compose down
    - docker-compose build
    - docker-compose up tester-image

请注意，在 docker-compose earlier than 1.25 的版本中:

Since the image uses docker-compose-entrypoint.sh as entrypoint you'll need to override it back to /bin/sh -c in your .gitlab-ci.yml. Otherwise your pipeline will fail with No such command: sh

    image:
      name: docker/compose:latest
      entrypoint: ["/bin/sh", "-c"]
