Can't configure locale in Docker image

问题

I'm trying to install a locale file in my Docker image, but for some reason it doesn't install correctly.

These lines inside my Dockerfile do configure + install the locale files:

# Install and configure locales
RUN ["apt-get", "install", "-y", "locales"]
RUN ["locale-gen", "nl_NL.UTF-8"]
RUN ["dpkg-reconfigure", "locales"]
RUN ["update-locale"]
ENV LANG nl_NL.UTF-8

The image is created succesfully. When I run docker exec **ID** locale -a I still get the following error:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
C
C.UTF-8
POSIX

So I guess it didn't installed the locale files correctly. Anyone could help me with this?

回答1:

Try both locales and locales-all

like :

RUN apt-get update && apt-get install -y --no-install-recommends \
    locales \
    locales-all \
