Windows docker image .net core throws error

[atulthummar]

C:\WINDOWS\system32>kubectl logs jobprocessor-function-cfb955886-fmqbd -p
It was not possible to find any installed .NET Core SDKs
Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
https://aka.ms/dotnet-download

getting above while checking pod log and pod status CrashLoopBackOff

Even though i have installed - FROM mcr.microsoft.com/dotnet/core/runtime:3.1-nanoserver-1803 AS base

Can you share what you Dockerfile looks like? Usually this error is caused by one of two things. You are either trying to use the .NET CLI in a runtime image which does not contain the CLI. Use the dotnet/sdk images if this is the case. The other cause is that you are trying to run an application via dotnet <YourAppName> but either the app doesn't exist as expected or you are using a linux image (a case sensitive environment) and the casing is incorrect.

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/azure-functions/dotnet:3.0-nanoserver-1809 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/sdk:3.1-nanoserver-1809 AS build
WORKDIR /src
COPY ["FunctionApp.csproj", "FunctionApp/"]
RUN dotnet restore "FunctionApp/FunctionApp.csproj"
COPY . .
WORKDIR "/src/FunctionApp"
RUN dotnet build "FunctionApp.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "FunctionApp.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app

Do you have the command that is being used to run the container?

[atulthummar]

I have used Azure function 3.1 its on service bus trigger - I have to run on window docker image
If i pass - ENTRYPOINT ["dotnet", "FunctionApp.dll"]
Then pod logs shows message as "It was not possible to find any installed .NET Core SDKs
Did you mean to run .NET Core SDK commands? Install a .NET Core SDK from:
https://aka.ms/dotnet-download"

If not then it shows
Content root path: C:\app
Now listening on: http://[::]:80
Application started. Press Ctrl+C to shut down.

.Net core function runtime should be required as its already install with base image FROM mcr.microsoft.com/azure-functions/dotnet:3.0-nanoserver-1809 AS base

Any input ?
