Encoding Problems when running an app in docker (Python, Java, Ruby, …) with Ubuntu Containers (ascii, utf-8)
问题 On my own PC the application runs nice, but when it gets deployed into docker, it fails because of invalid characters. I am using the ubuntu:lastest container and python3 , java and ruby . 回答1: You need to set the locale correct. This is the minimal correct Dockerfile: FROM ubuntu:latest RUN locale-gen en_US.UTF-8 ENV LANG en_US.UTF-8 ENV LANGUAGE en_US:en ENV LC_ALL en_US.UTF-8 The usual docker images don't specify a locales. You see it if you bash into it and execute locale : sudo docker
