【云计算】Docker 镜像如何设置语言环境？bash: warning: setlocale: LC_ALL: cannot change locale (en_US)

解决方案：

# set default language environment
RUN locale-gen en_US.UTF-8 \
    && dpkg-reconfigure locales
ENV LC_ALL=en_US.UTF-8
ENV LANG=en_US.UTF-8
ENV LANGUAGE=en_US.UTF-8


OR:

sudo locale-gen en_US.UTF-8

sudo dpkg-reconfigure locales

vi /etc/default/locale
LC_ALL=en_US.UTF-8 
LANG=en_US.UTF-8
重新登录服务器，warning 警告不再出现，问题解决
