Gitlab CI 创建 angularjs和 .net 的容器镜像

这两天有个新的需求，需要在Gitlab里面配置两个子目录来存放不同的angularjs和.net的代码，然后各自生成对应的docker image。基本结构是这样的，最外面有个.gitlab-ci.yml 文件，他同级的有两个目录。在这个外面的.gitlab-ci.yml里面循环调用子目录里面的.gitlab-ci.yml,实现二级目录的pipeline。

.gitlab-ci.yml angularjs_project - .gitlab-ci.yml - Dockerfile - other files.. dotnet_project - .gitlab-ci.yml - Dockerfile - other files..

下面看看具体如何实现。

父目录

最外面的.gitlab-ci.yml

stages: - tag - child_pipeline dotnet: stage: child_pipeline variables: CHILD_PIPELINE_EXECUTION_CONTEXT: "dotnet_project" trigger: include: .sub-gitlab-ci.yml strategy: depend angularjs: stage: child_pipeline variables: CHILD_PIPELINE_EXECUTION_CONTEXT: "angularjs_project" trigger: include: .sub-gitlab-ci.yml strategy: depend

子目录 Anjularjs

首先我们先建立一个演示用的anjularjs的程序

ng new app-to-run-inside-docker cd app-to-run-inside-docker ng serve

如果成功的话可以直接通过 Http://localhost:4200 访问然后我们生成一个dist的目录

ng build --prod

把这个目录拷到nginx里面就能跑了Dockerfile

FROM nginx:alpine COPY /dist/app-to-run-inside-docker /usr/share/nginx/html EXPOSE 80

如果我们把build和copy的步骤放在一起，可以优化一下Dockerfile

FROM node:alpine AS my-app-build WORKDIR /app COPY . . RUN npm ci && npm run build FROM nginx:alpine COPY --from=my-app-build /app/dist/app-to-run-inside-docker /usr/share/nginx/html EXPOSE 80

把这些对应的文件commit到repo的目录里面就okay了

子目录 .net core

我们给.net core也生成一个演示的程序

dotnet new webapp -o aspnetcoreapp

然后创建对应的Dockerfile

ROM mcr.microsoft.com/dotnet/sdk:6.0 AS build-env WORKDIR /app #Copy csproj and restore as distinct layers COPY *.csproj ./ RUN dotnet restore #Copy everything else and build COPY . ./ RUN dotnet publish -c Release -o out #Build runtime image FROM mcr.microsoft.com/dotnet/aspnet:6.0 WORKDIR /app COPY --from=build-env /app/out . ENTRYPOINT ["dotnet", "aspnetcoreapp.dll"]

commit 代码

下面是一个demo的 .git-lab.yml 文件，其中我调用了2个开源的小项目，一个可以获取当前branch的tag，自动根据版本号命名规则升级版本号，保存在.env里面的tagName里面，另外一个可以读取这个值，然后给branch赋值新的tag。其余部分就是docker build和保存docker image到Azure Container Registry里面。 注意我使用了Docker in Docker，因此如果runner是自己启动的，记得修改配置文件。https://techoverflow.net/2021/01/12/how-to-fix-gitlab-ci-error-during-connect-post-http-docker2375-v1-40-auth-dial-tcp-lookup-docker-on-no-such-host/
