Hi,

I create a docker image on Linux for Umbraco version 13.1.1. Umbraco works on dev machine but when it start into the container it crash and I've this error:

System.Globalization.CultureNotFoundException: Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information. (Parameter 'name') agripass360-1 | en-US is an invalid culture identifier. at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride)

On Linux I installed the ICU libs and part of the docker file is:

FROM mcr.microsoft.com/dotnet/aspnet:8.0-jammy AS base USER root

Install cultures (same approach as Alpine SDK image) for ALPINE

RUN apk add --no-cache icu-libs icu-data-full ENV DOTNETSYSTEMGLOBALIZATION_INVARIANT=true ENV

DOTNETRUNNINGIN_CONTAINER=true RUN apt-get update && apt-get install -y libicu-dev WORKDIR /app EXPOSE 8080 EXPOSE 8081

....

FROM base AS final ENV DOTNETSYSTEMGLOBALIZATIONINVARIANT=true RUN apt-get install -y libicu-dev WORKDIR /app COPY --from=publish /app/publish . USER root RUN mkdir -p /app/umbraco/Data/TEMP RUN mkdir -p /app/umbraco/Data/TEMP/FileUploads RUN chown -R $APPUID:$APPUID /app USER $APPUID ENTRYPOINT ["dotnet", "dddd.dll"]

Why?
