Docker 未在 Django 应用程序上提交工作服

Question

我正在使用 Docker 开发 Django 项目。我已经配置了 Travis-Ci 并且我想将测试覆盖率提交给 coveralls。但是，它没有按预期工作。任何帮助将不胜感激。

这是我遇到的错误

Answer 1

要了解为什么未提交覆盖范围，您必须了解 docker 容器的运行方式。

创建容器是为了模拟一个独立的单元。这意味着全局上下文中运行的命令与容器上下文中运行的命令不同。

在您的情况下，您正在运行测试并在容器的上下文中生成覆盖率报告，然后尝试从全局上下文向工作服提交报告。

由于文件在容器中，coveralls 命令找不到报告，因此不会提交任何内容。

您可以参考这里提供的答案来解决这个问题：

或者查看 travis 提供的关于如何使用 docker 从 travis 提交工作服的文档： https://docs.travis-ci.com/user/coveralls/#using-coveralls-with-docker-builds

Answer 2

您必须运行容器内的工作服才能将覆盖生成的数据文件发送到 coveralls.io。您必须在 after_success 命令中再次运行覆盖范围，以便在工作服运行s 时容器中存在 .coverage 数据文件。您还必须将工作服回购令牌作为您在 travis https://docs.travis-ci.com/user/environment-variables#defining-variables-in-repository-settings.

中设置的环境变量传递

.travis.yml

language: python
python:
  - "3.7"

services: docker

before_script: pip install docker-compose

script:
  - docker-compose run web sh -c "coverage run manage.py test && flake8 && coverage report"
after_success:
  - docker-compose run web sh -c "coverage run manage.py test && TRAVIS_JOB_ID=$TRAVIS_JOB_ID TRAVIS_BRANCH=$TRAVIS_BRANCH COVERALLS_REPO_TOKEN=$COVERALLS_REPO_TOKEN coveralls"

您需要确保将您的 git 回购文件复制到工作服的容器中，以便准确报告分支并使徽章正常工作。您可能还需要在容器中安装 git。
