Culture is not supported 1033 (0x0409)

Question

i am using dotnet 2.2 image to run my service application at environment: docker windows (linux container)

FROM mcr.microsoft.com/dotnet/core/sdk:2.2-alpine AS build-env

and hitting below error:

System.Globalization.CultureNotFoundException: Culture is not supported.| Parameter name: culture| 1033 (0x0409) is an invalid culture identifier.

i have set following at docker file. build without problem but still error displayed when application is running

# Set the locale
ENV LANG C.UTF-8
ENV LC_ALL C.UTF-8 

Answer 1

this works.

updating the solution: i have run the same docker image at teamcity , linux based environement and the extra lines to define codepage is not needed at all.

so this issue is only happend at docker windows (linux container) run at Windows 10.

# Disable the invariant mode (set in base image)
RUN apk add --no-cache icu-libs

ENV DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=false \
    LC_ALL=en_US.UTF-8 \
    LANG=en_US.UTF-8
