How I use locales in Alpine #144
Comments
|
Unfortunately, the musl libc locale system doesn't appear to be very complete at the moment. There is a little bit of information on it at http://www.openwall.com/lists/musl/2014/08/01/1. But there are no tools in Alpine to generate locales or set up the Sorry :( Referencing #102 as well. |
|
Well, for this app I will use another distro :( |
|
Is there a reason that this was closed? It seems to me there is still no way to generate locales? |
|
I wrote some simple tool with many bugs. It contains locale executable and template for generate MUSL locale files; |
|
So there is now no easy way to install locale (cs_CZ.utf8) in container? I would need it for my PHP application to print translated dates. |
|
Install my tool, make a MO file for cs_CZ.utf8 (and make a PR). And use cs_CZ.utf8 as LANG and LC_ALL. |

I encountered the same issue too when using In your FROM alpine:3.6

I'm having some issues with localisation on alpine and i can see that i'm not the only one. @alextanhongpin I've tried what you suggested. I can now do C But when trying to change the locale (php command LANG= (here i tried changing it to following; da_DK.utf8, da_DK, da_DK.utf-8, da_DK.UTF-8, da_DK.UTF8 with no luck) Can anybody help? Is it even possible to make it work? |
|
You try to using glibc locales in musl app, it is strange. Do you tried my workaround? |
|
@rilian-la-te Yes i tried. Don't have cmake installed on my server. Tried on my mac as a proof of concept which resulted in some missing libraries which lead to a dead end. Might give it another try |
|
Sorry, I do not know autotools. You need to have argp and libintl to build it in Alpine. I can switch to meson, if python is more acceptable. |
|
Hi @rilian-la-te. I'm back at this problem. I successfully installed your tool but how do i generate the locale?
How do i make a MO file for e.g. da_DK.utf8 and what is PR? Can you give a few hints :D? |
|
PR is pull request. For making a MO file you need a PO file and gettext. PO file is a text file with MUSL localization. And you can use my musl-locales to get a locale program and auto install of PO (it will automatically makes it MO and install in right place and sets requiered environment variable) |
lol 🤣. Okay makes sense. I ran your musl-locales and got this output:
This means that the following languages were installed: ch_DE.UTF-8, de_CH.UTF-8,en_US.UTF-8, ru_RU.UTF-8. Right? When i try to setlocale to one of these locales, it does not work. If i do /usr/local/bin/locale -a (to list all enabled locales) it only outputs: I have tried setting the Any ideas to what i'm doing wrong? |
|
show me MUSL_LOCPATH |
|
|
It should be /usr/local/share/i18n/locales/musl |
|
set it so and try again |
Tried setting it to
Might just be an impossible task at this moment :( |

Based on the musl-locales tool by @rilian-la-te, I created a simple example image showing how to use musl locales with docker-alpine. It creates a single docker layer weighting around 150 kb, while containing a few example locales. They mostly aren't full-blown localizations, but at least allow you to use localized time and date functions. You can find it here: https://github.com/Auswaschbar/alpine-localized-docker |
This is awesome, thanks! I can see that C.UTF-8
en_US.UTF-8
ch_DE.UTF-8
de_DE.UTF-8
ru_RU.UTF-8
de_CH.UTF-8
en_GB.UTF-8
fr_FR.UTF-8What would it take to add more languages? Do we just need to push new .PO files to the https://gitlab.com/rilian-la-te/musl-locales repo? |
|
Yes, just push it to me) And if you see untranslated strings, you just need to modify .pot file (it is handmade, not generated). |

Here is how I managed to install locales on alpine 3.9 (probably works on earlier versions too) |
Hi I used this gist ton install it on php:7.2.19-fpm-alpine3.9 image. Locales seem to be installed if I use usr/glibc-compat/bin/locale -a but they can't be used within php, strftime still returns english words even with setting setlocale() with another locale. |
|
@curunoir You're right, locales are installed, but php doesn't use them either. I'm trying to investigate why, will post back if I find anything. I also tested: EDIT: The gist I posted above does not seem to work. So I used rilian-la-te's solution above (has only following locales tho: Basically the steps are: then using
To check for presence of the locales. And to be sure it works, you can type: Edit: Replaced github link with gitlab instead which is more up to date. |
|
@Herz3h I've been putting together an APKBUILD file for rilian-la-te's solution. Although the locales appear to work with the date command in a terminal, have you been able to figure out why they do not work in PHP with setlocale? Output: |
|
From #144 (comment)
While this is not wrong, I suggest to clone project from GitLab instead of Github, because it seems more updated there. For example, Gitlab repository has es_ES support. So use: Edit: Linked comment was updated and now points to GitLab, so don't get confused if you see there the GitLab URL :) |
|
You're also welcome to use this APKBUILD file to build packages locally. I hope to eventually have it included in Alpine's package repositories. |
|
It looks like the IntlDateFormatter class from the PHP Intl extension can be used on Alpine which relies on ICU: Output: I just installed apache2 php7 php7-apache2 php7-intl and enabled the Intl extension in php.ini. |
Hi @Herz3h, do you have any update about your investigation? |
|
@edoardomistretta the steps I posted above (with musl) are the ones I currently use and it's working just fine. |

This is my Postgres-Alpine locale:
This is my Postgres db settings:
Why my monetary values aren't in pt_BR format?
The amounts should be as: R$ 100,00 What remains to be done for this to work? |
|
For anyone else stumbling upon this, musl-libc doesn't support LC_MONETARY yet. It is on their roadmap with no target date. |
|
Works with #144 (comment). |
