Adding locales to an alpine container in a single easy step.

Building an image

Build a test image named alpine-localized with

docker build -t alpine-localized .

Test if locales work with

docker run alpine-localized sh -c 'date && LC_ALL=de_DE.UTF-8 date'

Incorporating the image into your container

Either use this image as a base, or copy the two steps from this dockerfile into your own.

Using locales

  • Set the environment variables LC_... to your favorite locale.
  • in C(++), using newlocale() also works
  • either way, as of now, musl requires you to use the full locale name like de_DE.UTF-8. Using just de_DE doesn't seem to work

Creating or modifying locales

Locales for Alpine Linux are maintained on https://git.adelielinux.org/adelie/musl-locales (fork of https://gitlab.com/rilian-la-te/musl-locales). Currently, the selection of locales is limited and incomplete, but you are welcome to create and contribute your own, you can find more info on that repo.
