如何将构建阶段创建的文件与同一阶段的dockerfile一起使用？

Question

问题：在构建阶段，我使用一个shell执行器来“zip helloworld.zip helloworld.txt”，然后，我“docker build-t myproject/myapp.”，我希望在其中复制helloworld.zip/“，但似乎我创建的zip文件在docker构建上下文中不可用。我没有将helloworld.zip文件保存到正确的位置吗？还是别的什么？我的长期目标是编写一个python应用程序，并在构建阶段编译为单个可执行文件并复制到docker容器中。

#cat helloworld.txt
hello world

#cat dockerfile
FROM centos:7
COPY helloworld.zip /
CMD ["/bin/bash"]

#cat gitlab-ci.yml
stages:
    - build
    - test
    - release
    - deploy

variables:
  IMAGE_TEST_NAME: $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_SLUG
  IMAGE_RELEASE_NAME: $CI_REGISTRY_IMAGE:latest

before_script:
  - echo "$CI_REGISTRY_PASSWORD" | docker login -u "$CI_REGISTRY_USER" "$CI_REGISTRY" --password-stdin

build:
  stage: build
  script:
    - echo "compile the program"
    - zip zipfile.zip helloworld.txt 
    - docker build --pull -t $IMAGE_TEST_NAME .
    - docker push $IMAGE_TEST_NAME

test:
  stage: test
  script: 
    - docker pull $IMAGE_TEST_NAME
    - docker run $IMAGE_TEST_NAME yum install unzip -y && unzip /helloworld.zip && cat /helloworld.txt

release:
  stage: release
  script:
    - docker pull $IMAGE_TEST_NAME
    - docker tag $IMAGE_TEST_NAME $IMAGE_RELEASE_NAME
    - docker push $IMAGE_RELEASE_NAME
  only:
    - master

deploy:
  stage: deploy
  script:
    - ./deploy.sh
  only:
    - master
  when: manual

我希望在同一阶段（在本例中为构建）内，可以运行zip之类的程序，然后在docker构建过程中将zip文件复制到新建docker映像中的给定目录中。

Answer 1

这是不可能的。Gitlab CI的作业模型假设同一阶段的作业是独立的。

有关gitlab-ci.yml中的dependencies关键字，请参阅手册：

此功能[...]允许您定义要在不同作业之间传递的工件。
