【雲計算】Docker 鏡像如何設定語言環境？bash: warning: setlocale: LC_ALL: cannot change locale (en_US)

解決方案：

# 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
重新登入伺服器，warning 警告不再出現，問題解決
