WORKDIR /app
COPY --frompublish /app/publish .
ENTRYPOINT [dotnet, DaprTest1.ServiceApi1.dll] 在解决方案根目录增加文件build-docker-images.ps1 以生成Docker image,文件内容如下:docker build -t dapr-test1/blazorweb:1.0 -f Server/Dockerfile .docker build -t dapr-test1/serviceapi1:1.0 -f ServiceApi/DaprTest1.ServiceApi1/Dockerfile . 在解决方案根目录执行build-docker-images.ps1后, 可看到生成的两个镜像: 1.5.2 部署Docker镜像到K8s在解决方案根目录新建文件夹 Deploy, 放置k8s部署文件 其中deploy.ps1 为部署命令,内容如下:kubectl apply -f namespace.yaml -f dapr-config.yaml -f blazorweb.yaml -f serviceapi1.yaml 部署完成后,可通过端口转发给node看到效果. 代码地址iamxiaozhuang/dapr-test (github.com)
