Running .NET 6 project in Docker throws Globalization.CultureNotFoundException

I have upgraded API project from .NET 5 to .NET 6 successfully and running fine when executed locally (without Docker).

I have also updated the version in Dockerfile from "5.0-alpine3.13" to "6.0-alpine3.14" as below (only change I made).

ARG VERSION=6.0-alpine3.14

#Runtime stage
FROM mcr.microsoft.com/dotnet/aspnet:$VERSION AS base
EXPOSE 8080
ENV DOTNET_RUNNING_IN_CONTAINER=true \
  ASPNETCORE_URLS=http://+:8080

#Build stage
FROM mcr.microsoft.com/dotnet/sdk:$VERSION AS build
WORKDIR /src
COPY ["/src/RM.Api/RM.Api.csproj", "/src/RM.Api/"]
RUN dotnet restore "/src/RM.Api/RM.Api.csproj"
COPY . .
WORKDIR "/src/src/RM.Api"

#Publish dotnet project
FROM build AS publish
ARG BUILDCONFIG=RELEASE
RUN dotnet publish "RM.Api.csproj" -c $BUILDCONFIG -o /app/publish

#Create local user, change ownership, and copy artifacts
FROM base AS final
WORKDIR /app
RUN adduser \
  --disabled-password \
  --home /app \
  --gecos '' app \
  && chown -R app /app
USER app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "RM.Api.dll"]

But when I run this .NET 6 project in Docker it throws the below Azure.Storage exception in the Startup.cs file.

Full stack trace is here.

I have updated the Dockerfile as below but it did not work. Can any one help here?

You've put the ENV statement in the 'build' part of the Dockerfile which means that it doesn't get placed in the final image. Either put it in the 'base' part or the 'final' part.

I'd put it in the 'base' section with the other ENV statements.

You might also want to move the apk add to the base or final sections of the file, if you want the software installed in the final image.
