Docker Compose JVM 参数 [英] Docker Compose JVM parameters

问题描述

我编写了一个 Java 应用程序，它接受一个环境变量，该变量接受一个参数来为 JWT 令牌盐键设置一个键.有没有办法让我在 Docker Compose 中传递命令变量?

I wrote a java application that takes an environment variable that takes an argument to set a key for a JWT token salt key. Is there a way for me to pass the command variables in Docker Compose?

java -Djava.security.egd=file:/dev/./urandom -jar /user-profile-api.jar --key=blah

运行docker镜像你只需

And to run the docker image you just

docker run -p 8080:8080 docker_image --key=blah

推荐答案

如果您已经能够使用以下方法运行您的 docker 容器:

If you already are able to run your docker container using:

docker run -p 8080:8080 docker_image --key=blah

然后，您只需要将撰写文件中 service 的 command 属性覆盖为 --key=blah.所以:

Then you just need to override the command attribute for your service in the compose file to --key=blah. So:

services:
  app:
    command: --key=blah
...
