有人可以使用Docker在Mesosphere DC / OS上创建Cassandra集群吗?
问题在于,Cassandra容器每隔几秒钟就会不断启动。
似乎Marathon无法获得新创建的容器的运行状况,因为它一直在不断创建新容器。在DC / OS GUI服务调试中,它显示
State: TASK_FAILED
Message: Container terminated with signal Broken pipe
在机器上进行检查时,容器每隔一两分钟就会启动并运行,并且新容器也在不断创建。
为什么马拉松无法从成功启动的容器中获得正确的响应,从而使其无法再创建新容器?
我正在共享该服务的当前JSON配置。 Cassandra.json

如果有人知道发生了什么,请提供帮助。如果需要,我可以分享更多细节。
