Ubuntu Docker container missing Chinese

Posted on Sep 29, 2020 By Jason Liu

  1. Ubuntu Docker container doesn’t have Chinese by default.
    Solution:
    • Option 1: install Chinese manually 
        #Check locale
  locale -a
  #Check installed packages
  dpkg -l | less

  #Set environment variables LANG, and LC_ALL
  LANG='C.UTF-8'
  set |grep LANG
  LC_ALL='C.UTF-8'
  set |grep LC_ALL
  export LANG
  printenv |grep LANG
  export LC_ALL
  printenv |grep LC_ALL
    • Option 2: install it in Dockerfile 
        RUN apt-get update
  RUN apt-get install -y locales
  ENV LANG C.UTF-8
  ENV LC_ALL C.UTF-8
  2. Failed to install locales. 
     apt-get install -y locales
 E: Package 'locales' has no installation candidate

    Solution:
    Run apt-get update first
