如何在 Docker 容器内设置 Java 堆大小(Xms/Xmx)? [英] How to set Java heap size (Xms/Xmx) inside Docker container?

问题描述

在提出这个问题时，Docker 看起来足够新，无法在网络上回答这个问题.我找到的唯一地方是这篇文章作者说这很难，仅此而已.

As of raising this question, Docker looks to be new enough to not have answers to this question on the net. The only place I found is this article in which the author is saying it is hard, and that's it.

推荐答案

我同意这取决于您使用的容器.如果你使用的是官方的Tomcat镜像，看起来很简单，你会需要使用堆设置传递 JAVA_OPTS 环境变量:

I agree that it depends on what container you're using. If you are using the official Tomcat image, it looks like it's simple enough, you will need to pass the JAVA_OPTS environment variable with your heap settings:

docker run --rm -e JAVA_OPTS='-Xmx1g' tomcat
