- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我有一个使用 Paket 的 F# 项目构建的 docker 镜像。在运行时,图像失败并显示:
It was not possible to find any compatible framework version The specified framework 'Microsoft.AspNetCore.App', version '2.2.7' was not found.
dockerfile
看起来像这样:
# Two stage build because Paket means project files reference external files
# via <Import Project="..\.paket\Paket.Restore.targets" />
# https://github.com/fsprojects/Paket/issues/3006#issuecomment-359750323
FROM microsoft/dotnet:2.2-sdk-alpine AS build
RUN apk update \
&& apk add --no-cache bash
WORKDIR /app
# copy fsproj and restore as distinct layers
COPY MyCompany.WebApi/MyCompany.WebApi.fsproj ./MyCompany.WebApi/
COPY NuGet.config ./
RUN dotnet restore MyCompany.WebApi/MyCompany.WebApi.fsproj --configfile NuGet.config
# copy everything else and build
COPY . ./
RUN dotnet publish MyCompany.WebApi/MyCompany.WebApi.fsproj -c Release -o out
# build runtime image
FROM microsoft/dotnet:2.2-sdk-alpine AS final
RUN apk update \
&& apk add --no-cache bash
WORKDIR /app
COPY --from=build /app/MyCompany.WebApi/out ./
ENTRYPOINT ["dotnet", "MyCompany.WebApi.dll"]
2.2-runtime-alpine
也会出现同样的问题作为

最佳答案
我想我已经解决了这个问题。将基本镜像更改为我在 Microsoft 教程中找到的引用,并删除了 apk update
阶段(因为这会返回带有此新基础镜像的非零退出代码)。所以这是我的dockerfile
现在。
FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build
WORKDIR /app
# copy fsproj and restore as distinct layers
COPY MyCompany.WebApi/MyCompany.WebApi.fsproj ./MyCompany.WebApi/
COPY NuGet.config ./
RUN dotnet restore MyCompany.WebApi/MyCompany.WebApi.fsproj --configfile NuGet.config
# copy everything else and build
COPY . ./
RUN dotnet publish MyCompany.WebApi/MyCompany.WebApi.fsproj -c Release -o out
# build runtime image
