docker - 如何使用 docker 在 Gitlab CI 中执行 gitversion？

Question

我的 gitlab-ci.yml 中有这个:

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: "/certs"
  DOCKER_HOST: "tcp://docker:2375"

determine version:
  stage: preparation
  tags: 
    - docker
  image: gittools/gitversion
  script:
    - pwd
    - echo $(pwd)
    - gitversion /output json /showvariable FullSemVer > version.txt
    - cat version.txt
  artifacts:
    paths:
      - version.txt
    expire_in: 1 hr

当它在我的运行者身上运行时，我得到了这个:

如何让 Gitversion 确定我的构建版本？我将它用于所有不是使用 Docker 构建的代码，我可以使用它，但我觉得它也应该在容器中工作。

另外，pwd 和 echo $(pwd) 都没有出现在输出中，我怎样才能在输出中得到一些东西？

Answer 1

both pwd and echo $(pwd) do not show up in the output,

这是因为在容器内实际上没有执行任何命令，因为这张图片 gittools/gitversion包含以下入口点:

ENTRYPOINT ["dotnet", "/app/GitVersion.dll"]

与 https://hub.docker.com/r/gittools/gitversion 中建议的单行兼容:

docker run --rm -v "$(pwd):/repo" gittools/gitversion:latest-linux-netcoreapp2.2 /repo

当没有提供命令行参数时会失败，因此会因 docker exec - 暗示使用 GitLab CI 而失败。

此外，该图像似乎不支持 gitversion 命令，而是支持 dotnet/app/GitVersion.dll。

解决方案 1

作为一种解决方法，您可能想要覆盖入口点并尝试:

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: "/certs"
  DOCKER_HOST: "tcp://docker:2375"

determine version:
  stage: preparation
  tags: 
    - docker
  image:
    name: gittools/gitversion
    entrypoint: /bin/bash

  script:
    - pwd
    - dotnet /app/GitVersion.dll /output json /showvariable FullSemVer > version.txt
    - cat version.txt
  artifacts:
    paths:
      - version.txt
    expire_in: 1 hr

解决方案 2

使用手工制作的 docker run 命令，using Docker-in-Docker (dind):

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: "/certs"
  DOCKER_HOST: "tcp://docker:2375"

determine-version:
  stage: preparation
  tags: 
    - docker
  image: docker:latest
  services:
    - docker:dind

  script:
    - pwd
    - docker run --rm -v "$(pwd):/repo" gittools/gitversion:latest-linux-netcoreapp2.2 /repo /output json /showvariable FullSemVer > version.txt
    - cat version.txt
  artifacts:
    paths:
      - version.txt
    expire_in: 1 hr
