gitlab-ci 构建 asp.net core docker

Question

我正在从事一个 gitlab CI/CD 项目，以将asp.net core应用程序构建到docker. 目前我有两种可能的实现方式。第一个在 中有完整的逻辑Dockerfile，但我无法以这种方式（构建、测试、发布）可视化 Gitlab 中的各个阶段。所以我想把主要的逻辑移到gitlab-ci.yml文件中。但现在困扰我的是我必须docker dotnet versions在 2 个地方（sdk:3.1，aspnet:3.1.1-alpine3.10）管理图像。通过交付版本是个好主意build-arg还是有更优雅的解决方案？

.gitlab-ci.yml

stages:
  - build
  - test
  - docker

build:
  stage: build
  image: mcr.microsoft.com/dotnet/core/sdk:3.1
  only:
    - master
  script:
    - cd src
    - dotnet restore --interactive
    - dotnet build --configuration Release
    - dotnet publish --configuration Release --output ../publish/
  artifacts:
    paths:
      - ./publish/*.*
    expire_in: 1 week
  tags:
  - docker

test:
  stage: test
  image: mcr.microsoft.com/dotnet/core/sdk:3.1
  only:
    - master
  script:
    - cd src
    - dotnet test --test-adapter-path:. --logger:"junit;LogFilePath=../../MyProject.xml"
  artifacts:
    paths:
      - ./MyProject.xml
    reports:
      junit: ./MyProject.xml
  tags:
  - docker

docker:
  stage: docker
  image: docker:stable
  services:
    - docker:dind
  variables:
    DOCKER_DRIVER: overlay2
    DOCKER_TLS_CERTDIR: ""
  only:
    - master
  script:
    - docker login -u "gitlab-ci-token" -p "$CI_JOB_TOKEN" $CI_REGISTRY
    - docker build --tag "$CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA" --tag "$CI_REGISTRY_IMAGE:latest" --build-arg EXECUTABLE=Test.WebApi.dll .
    - docker push "$CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA"
    - docker push "$CI_REGISTRY_IMAGE:latest"
  tags:
  - docker

文件

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1.1-alpine3.10
ARG EXECUTABLE

WORKDIR /app
COPY /publish .

ENV ASPNETCORE_URLS "http://*:5000"
ENV ASPNETCORE_ENVIRONMENT "Staging"
CMD ["dotnet", "$EXECUTABLE"]

这是我的解决方案，我已经定义了上面的变量并将它们在 docker 文件中替换为 sed

我的解决方案有这两个项目

• Test.WebApi（WebApi 项目）
• Test.WebApi.UnitTest（单元测试项目）

@ThomasBrüggemann 感谢您的灵感。

.gitlab-ci.yml

variables:
    PROJECT_NAME: "Test.WebApi"
    BUILD_IMAGE: "mcr.microsoft.com/dotnet/core/sdk:3.1"
    RUNTIME_IMAGE: "mcr.microsoft.com/dotnet/core/aspnet:3.1.1-alpine3.10"

stages:
  - build
  - test
  - docker

build:
  stage: build
  image: $BUILD_IMAGE
  only:
    - master
  script:
    - cd src/$PROJECT_NAME
    - dotnet restore --interactive
    - dotnet build --configuration Release
    - dotnet publish --configuration Release --output ../../publish/
  artifacts:
    paths:
      - ./publish/*
    expire_in: 1 week
  tags:
  - docker
  
test:
  stage: test
  image: $BUILD_IMAGE
  only:
    - master
  script:
    - cd src/$PROJECT_NAME.UnitTest
    - dotnet test --test-adapter-path:. --logger:"junit;LogFilePath=../../UnitTestResult.xml"
  artifacts:
    paths:
      - ./UnitTestResult.xml
    reports:
      junit: ./UnitTestResult.xml
  tags:
  - docker

docker:
  stage: docker
  image: docker:stable
  services:
    - docker:18.09.7-dind
  variables:
    DOCKER_DRIVER: overlay2
    DOCKER_TLS_CERTDIR: ""
  only:
    - master
  script:
    # Prepare Dockerfile
    - sed -i "s~\$DOCKERIMAGE~$RUNTIME_IMAGE~g" Dockerfile
    - sed -i 's/$ENVIRONMENT/Staging/g' Dockerfile
    - sed -i "s/\$ENTRYPOINT/$PROJECT_NAME.dll/g" Dockerfile

    # Process Dockerfile
    - docker login -u "gitlab-ci-token" -p "$CI_JOB_TOKEN" $CI_REGISTRY
    - docker build --tag "$CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA" --tag "$CI_REGISTRY_IMAGE:latest" .
    - docker push "$CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA"
    - docker push "$CI_REGISTRY_IMAGE:latest"
  tags:
  - docker

文件

FROM $DOCKERIMAGE

WORKDIR /app
COPY /publish .

EXPOSE 5000/tcp

ENV ASPNETCORE_URLS "http://*:5000"
ENV ASPNETCORE_ENVIRONMENT "$ENVIRONMENT"
CMD ["dotnet", "$ENTRYPOINT"]
