在Docker中更改Ubuntu语言环境 [英] Change Ubuntu locale in Docker

问题描述

所以我要在pt_BR中使用Ubuntu和Postgresql设置docker映像，我想知道如何通过命令行更改默认语言环境而无需重新启动系统-这在Docker构建中是不可能的:) . 我在Debian中设法通过更改/etc/default/locale中的设置LANG，LANGUAGE和LC_ *变量，修改了/etc/locale.gen并运行了dpkg-reconfigure来做到这一点，如

So I'm setting up a docker image with Ubuntu and Postgresql in pt_BR and I'd like to know how can I change the default locale via command line without restarting the system - which is not possible in a Docker build :). I managed to do it in Debian by changing setting LANG,LANGUAGE and LC_* variables in /etc/default/locale, modifying /etc/locale.gen and running dpkg-reconfigure, as shown here. In Ubuntu it doesn't work.

推荐答案

它应该同样适用于Ubuntu.

It should work with Ubuntu similarly.

一个示例Dockerfile

A sample Dockerfile

FROM ubuntu
RUN  apt-get install -y language-pack-pt-base
ENV  LANG pt_BR.UTF-8

从该图像运行容器，ls --help将以葡萄牙语显示.

Running a container from that image, ls --help will be presented in Portuguese.
