add extra locale

[iStone]

currently within my docker:

$ locale -a
C
C.UTF-8
POSIX

so how to install extra locales? e.g. de_DE.UTF-8?

solved:
within docker:
apt-get -y install locales locales-all

Either one of those methods should work:

FROM postgres:X.Y
RUN sed -i 's/^# *\(en_US.UTF-8\|de_DE.UTF-8\)/\1/' /etc/locale.gen && \
        locale-gen
ENV LANG de_DE.utf8

or:

FROM postgres:X.Y
RUN localedef -i de_DE -c -f UTF-8 -A /usr/share/locale/locale.alias de_DE.UTF-8
ENV LANG de_DE.utf8

I use the first method till ages...

Don't ask me why the ENV LANG needs to be set to de_DE.utf8. Even though de_DE.UTF-8 would make more sense, it never worked for me.

Postgres is just used as an example. Pick whatever base image you want to use.
