docker ubuntu /bin/sh: 1: locale-gen: not found

Question

I put the locale setting codes below into my dockerfile,

FROM node:4-onbuild

# Set the locale
RUN locale-gen en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_U         


        

Answer 1

apt-get install -y locales
localedef -i en_US -c -f UTF-8 -A /usr/share/locale/locale.alias en_US.UTF-8

localedef is also good to use.
