gitlab-ci 构建 asp.net 核心 docker答案

【问题描述】：

我正在开发一个 gitlab CI/CD 项目，以将 asp.net core 应用程序构建到 docker 中。目前我有两种可能的实现方式。第一个在Dockerfile 中有完整的逻辑，但我无法以这种方式可视化 Gitlab 中的阶段（构建、测试、发布）。所以我想把主要逻辑移到gitlab-ci.yml文件中。但现在困扰我的是我必须在 2 个地方（sdk：3.1，aspnet：3.1.1-alpine3.10）管理图像docker dotnet versions。通过build-arg 提供版本是个好主意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

Dockerfile

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"]

【解决方案1】：

这是我的解决方案，我已经定义了上面的变量并在docker文件中将它们替换为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）

【讨论】：

GitLab 中的 Docker 镜像有什么问题吗？
@NiAu 他们在说什么问题？
表示GitLab找不到dotnet的docker镜像

【解决方案2】：

这里是 GitLab-Pipeline 中标记时的一些版本处理：

script:
    - COMMIT_DATE=$(git log -1 --format=%cd --date=iso-strict | grep -o '\([0-9]*\)' | tr -d '\n')
    - VERSION_PREFIX=$CI_COMMIT_TAG
    - VERSION_SUFFIX="${COMMIT_DATE::-6}"
    - echo $VERSION_PREFIX-$VERSION_SUFFIX
    - sed -i "s:<VersionPrefix>.*</VersionPrefix>:<VersionPrefix>$VERSION_PREFIX</VersionPrefix>:g" [PROJECT].csproj
    - dotnet publish --version-suffix $VERSION_SUFFIX -c Release -o ./out
    - docker build --tag "$CI_REGISTRY_IMAGE:$VERSION_PREFIX"
only:
    - tags

在项目文件中必须

<!-- Version is set by CI-Script do not modify manually -->
<VersionPrefix>0.0.0</VersionPrefix>
<Deterministic>False</Deterministic>

设置

也许这会有所帮助。在没有标记的情况下构建时可以做类似的事情。
