UTF-8编码在Docker中不起作用 [英] UTF-8 encoding not working in Docker

问题描述

我正在Docker容器（从Docker Compose开始）中运行Java程序，它抛出了一系列由UTF-8字符引起的错误（因为它们无法映射到ASCII字符集）。有没有一种方法可以从docker-compose文件中启用UTF-8编码？

I'm running a Java program from within a Docker container (started with Docker Compose) and it's throwing a bunch of errors caused by UTF-8 characters (as they can't be mapped to the ASCII charset). Is there a way to enable UTF-8 encoding from the docker-compose file?

推荐答案

您可以使用以下命令进行检查：设置Java参数，然后尝试运行Java程序-

You can check by using below command to set java parameters and then try to run your java program -

export JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF8

如果使用上述命令可以工作，请使用 ENV 命令进行设置

If it worked using above command, set it using an ENV command during docker image build.

此外，如果需要在bash_profile中进行设置，请参考以下Dockerfile部分-

Also if you need to set it in bash_profile, refer below portion of Dockerfile -

RUN echo "JAVA_HOME=/opt/jdk1.8.0_65" >> ~/.bash_profile
