Dotnet核心Web Api 3.1部署到Docker失败

Question

我试图对现有的Dotnetcore Web API进行容器化，但是在运行容器后看到以下错误。

我的项目结构 Marketplace | |__ Dockerfile | |__ Marketplace.Backend| |__Marketplace.API___ Marketplace.API.csproj | |__Markplace.Common__ Marketplace.Common.csproj

这是我的dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env
WORKDIR /app

COPY Marketplace.BackEnd/ ./src
WORKDIR /app/src
RUN dotnet restore
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1
WORKDIR /app
COPY --from=build-env /app/src/out .
ENTRYPOINT ["dotnet", "app/marketplace.api.dll"]

我可以验证生成的图像在app文件夹中是否包含marketplace.api.dll

Answer 1

您的工作目录是/ app，然后尝试运行

ENTRYPOINT ["dotnet", "app/marketplace.api.dll"]

我想你想要

ENTRYPOINT ["dotnet", "marketplace.api.dll"]

另外，请注意，Docker中的文件系统区分大小写，因此您实际上可能想要

ENTRYPOINT ["dotnet", "Marketplace.Api.dll"]
