dotnet核心容器未在kubernetes中启动，并显示错误“退回重新启动失败的容器”

在向项目添加其他引用之后，总是会发生这种情况。

kubectl日志容器不产生任何日志。

当我将图像拖到本地并通过运行时

docker run -it  app:latest . -p 80:80

在命令行中它将退出而不会引发任何错误。尝试添加详细的日志，并且不会引发任何错误。

从Visual Studio启动时尝试了ubuntu图像，它也运行良好。在本地编译可以很好地运行，并且通过Visual Studio运行docker可以很好地构建映像。

也尝试使用--no-cache标志进行构建，但未成功

如果不在docker容器中运行它，没有问题。恢复，构建或发布步骤没有错误。

在AKS 1.14.6上运行

WORKDIR /app
EXPOSE 80

COPY . .
WORKDIR "/src/Company.Reference.ApplicationHub"
RUN dotnet build "Company.Reference.ApplicationHub.csproj" -c Release -o /app -v diag

FROM build AS publish
RUN dotnet publish "Company.Reference.ApplicationHub.csproj" -c Release -o /app -v diag

FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "/app/Company.Reference.ApplicationHub.dll"]

在添加其他引用之前，它可以正常运行。可能是因为在某处缓存了吗？

您确定从docker运行与Kubernetes相同的映像吗？ “因为一旦构建了映像，内容（以及您的依存关系）就不会受到影响。

尝试使用其他标签重建图像（永远不要使用“ latest”）：

docker build . -t app:v1

然后使用app:v1作为Kubernetes中的图片

添加其他参考后，Dotnet容器不会在Kubernetes中启动
