Setting the language and region settings in a Windows Docker Container

问题

I'm creating a docker container based on the mcr.microsoft.com/dotnet/framework/runtime:4.8 base image.

This image is set to en_US, meaning that all the Windows language and region settings and default location is set to United States.

What I need to do is to change this to en_GB and change the location to United Kindom for the default user because I have a .Net application which has a dependency on a 3rd party library that uses this to output data to Excel. However nothing I've tried seems to be able to change the language and region settings thus far.

Things I have tried so far:

Attempted to use the intl.cpl International Settings to import the settings and update the default user:

# Set Locale and language 
& $env:SystemRoot\System32\control.exe "intl.cpl,,/f:`"UKRegion.xml`""

# Set Languages/culture
Set-Culture en-GB

Contents of UKRegion.xml:

<gs:GlobalizationServices xmlns:gs="urn:longhornGlobalizationUnattend">
    <!--User List-->
    <gs:UserList>
        <gs:User UserID="Current" CopySettingsToDefaultUserAcct="true" CopySettingsToSystemAcct="true"/> 
    </gs:UserList>

    <!-- user locale -->
    <gs:UserLocale> 
        <gs:Locale Name="en-GB" SetAsCurrent="true"/> 
    </gs:UserLocale>

    <!-- system locale -->
    <gs:SystemLocale Name="en-GB"/>
    <!-- GeoID -->

    <gs:LocationPreferences>
        <gs:GeoID Value="242"/>
    </gs:LocationPreferences>

    <gs:MUILanguagePreferences>
        <gs:MUILanguage Value="en-GB"/>
        <gs:MUIFallback Value="en-US"/>
    </gs:MUILanguagePreferences>

    <!-- input preferences -->
    <gs:InputPreferences>
        <!--en-GB-->
        <gs:InputLanguageID Action="add" ID="0809:00000809" Default="true"/> 
    </gs:InputPreferences>
</gs:GlobalizationServices>

Setting the values before starting the application in a powershell script:

Set-WinSystemLocale -SystemLocale en-GB
Set-WinHomeLocation -GeoId 242
Set-WinUserLanguageList -LanguageList (New-WinUserLanguageList -Language en-GB) -Force
Set-Location -Path "C:\\AppFolder"
.\AppExe.exe

After setting up the container and attaching I can see that Get-WinHomeLocation has updated, Get-WinUserLanguageList shows en_GB as an option, however the default language for windows from Get-WinSystemLocale still returns en-US

I also considered building my own base image from the en-GB Windows Server Core base image and running the framework setup that Microsoft runs to create the Framework runtime 4.8 image, but Microsoft don't seem to publish an en-GB base image!

Has anyone else come across this? How did you resolve it? Any other suggestions?

回答1:

The answer is that a Docker container inherits language settings from the host when using Process Isolation. So, change the host's language settings as desired. In PowerShell, to set the Region you can do this:

Set-WinSystemLocale en-GB
Restart-Computer

Now run Docker:

docker run -it --isolation=process mcr.microsoft.com/windows/servercore:1909 PowerShell

Within the Docker shell:

Get-WinSystemLocale

LCID             Name             DisplayName
----             ----             -----------
2057             en-GB            English (United Kingdom)
