[英]Spring-boot application won't boot at startup inside docker
I am running a simple spring-boot application inside a docker container. 我在docker容器中运行一个简单的spring-boot应用程序。 At startup whether started with
java -jar MY_JAR.jar
or mvn spring-boot:run
the application will always hang at the following point: 在启动时是否以
java -jar MY_JAR.jar
或mvn spring-boot:run
应用程序将始终挂起以下点:
2014-12-22 23:26:58.957 INFO 1 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean : Mapping filter: 'hiddenHttpMethodFilter' to: [/*]
Here's the catch, I can ONLY reproduce this on an Ubuntu 14.04 box in DigitalOcean (1CPU, 1GB MEM), even though it's running inside a container. 这是捕获,我只能在DigitalOcean(1CPU,1GB MEM)的Ubuntu 14.04盒子上重现这一点,即使它在容器内运行。 On my local machine (mac) everything runs fine.
在我的本地机器(mac)上一切正常。
The Dockerfile: Dockerfile:
FROM java:8
ADD target/MY_SERVICE-1.0-SNAPSHOT.jar /data/svc.jar
EXPOSE 8080
CMD ["java", "-jar", "/data/svc.jar"]

Got it! 得到它了! Once I installed
haveged
on the host, the process immediately moved forward, and spring booted fine. 一旦我安装
haveged
在主机上时,立即向前推进,和春季启动的罚款。 I will post more once I do a bit more research into how docker interacts with haveged
on the host. 一旦我对
haveged
如何与haveged
上的haveged
交互进行更多研究,我将发布更多内容。
In summary the following command issued on the host will fix the the issue: 总之,在主机上发出的以下命令将解决问题:
apt-get install haveged -y
If anyone has a detailed understanding of this, feel free to post! 如果有人对此有详细的了解,请随时发布!
The thing that I don't understand at the moment, is why the host machine needed extra code, and everything wasn't isolated within the docker container. 我目前还不了解的是,为什么主机需要额外的代码,并且所有东西都没有在docker容器中被隔离。
For those who might come here later. 对于那些可能会来这里的人。 I think easiest solution is to modify Dockerfile and have entry point as follows:
我认为最简单的解决方案是修改Dockerfile并具有如下入口点:
ENTRYPOINT ["java", **"-Djava.security.egd=file:/dev/./urandom"**,"-jar","app.jar"]
Had experience with apps hanging anywhere between 30 seconds and 15 minutes (or maybe more, but got killed). 有经验的应用程序挂在30秒到15分钟之间(或者更多,但被杀死)。
From the other post that shares details: 从另一篇分享细节的帖子:
Without this, Java uses /dev/random
to seed its SecureRandom
class, which can cause Java code to block unexpectedly. 如果没有这个,Java会使用
/dev/random
为其SecureRandom
类播种,这会导致Java代码意外阻塞。
Alternatively, in the $JAVA_HOME/jre/lib/security/java.security
configuration file, add the line 或者,在
$JAVA_HOME/jre/lib/security/java.security
配置文件中,添加该行
securerandom.source=file:/dev/./urandom
Footnote: In the above examples, you need the crazy-looking filename, eg, the extra /./
, to trick Java into accepting your filename. 脚注:在上面的示例中,您需要看起来很疯狂的文件名,例如额外的
/./
,以欺骗Java接受您的文件名。 If you just use /dev/urandom, Java decides you didn't really mean it and replaces what you wrote with /dev/random. 如果您只使用/ dev / urandom,Java决定您并不真正意味着它并替换您使用/ dev / random编写的内容。 Craziness!
疯狂!
