泽西岛灰熊HTTP服务器在集装箱docker内closures
我正试图在一个容器内执行一个Grizzly HTTP Server。
我的问题是，当我运行容器（使用docker-compose）容器在几秒钟后closures。
这是我的服务器Dockerfile ：

通常情况下，服务器必须听…
问题可能是你的主类在停止灰熊服务器之前正在等待input。 由于docker容器没有以交互模式运行，它将永远不会在命令行上得到input，并且System.in被终止。 mvn exec进程停止。
你应该find一种方法来保持灰熊服务器运行，而不用等待input。
就像是
server.start(); Thread.currentThread().join(); // instead of System.in.read();
编辑 ：似乎有这样的解决scheme已经描述这样grizzly-http-server-should-keep-running ，它也包含了一个正常的关机意味着一个shutdownhook。
