我正在使用 mesosphere 的 docker 镜像在我的家用计算机上运行 mesos 集群。在那个 mesos 集群中，我想使用 marathon 运行 docker 容器。
我有一个容器，我可以在我的 mesos slave 上手动运行(使用“docker run”)。但是，当我尝试将此应用提交到 marathon 时，出现以下错误。
在我不断看到的马拉松容器日志上:
marathon_1 | [2015-08-18 01:21:23,453] INFO Received status update for task neo4j.6cb4f068-4547-11e5-a85f-0242ac110004: TASK_FAILED (Docker container run error: Container exited on error: terminated with signal Aborted) (mesosphere.marathon.MarathonScheduler:96)

我可以看到一个 docker 容器在从属设备上启动(不久之后就死掉了)，如果我查看这些日志，它们包含:

我相信我已经解决的一些常见问题是:
1) 我对所有容器都使用了 --net=host
2) mesos_slave 容器有 --privileged=true
3)我的容器被命名为mesos_(显然mesos-*是mesos保留的)
4) 使用 MESOS_CONTAINERIZERS=docker,mesos 和 MESOS_EXECUTOR_REGISTRATION_TIMEOUT=5mins 部署我的 mesos_slave
为了完整起见，这是我发布到马拉松的 app.json:

"cpus": 0.3,
"mem": 512.0,
"disk": 2048.0,

]
},
"volumes": [
{
"containerPath": "/var/lib/neo4j",
"hostPath": "/var/lib/neo4j",
"mode": "RW"
}
]
}
}
我不确定我还缺少什么。似乎很多人都有类似的设置。

最佳答案
不确定到底是什么问题，但我已经能够在我的笔记本电脑上完成所有工作。我最终升级到了 mesoscloud docker 镜像:mesoscloud/mesos-master(slave):0.24.1-ubuntu-14.04。
关于docker - 在 docker + mesos + marathon 中运行 docker 容器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32062287/
我的瘦服务器配置了nginx，我的ROR应用程序正在它们上运行。在我发布代码更新时运行thinrestart会给我的应用程序带来一些停机时间。我试图弄清楚如何优雅地重启正在运行的Thin实例，但找不到好的解决方案。有没有人能做到这一点？ 最佳答案 #Restartjustthethinserverdescribedbythatconfigsudothin-C/etc/thin/mysite.ymlrestartNginx将继续运行并代理请求。如果您将Nginx设置为使用多个上游服务器，例如server{listen80;server
如何将send与+=一起使用？a=20;a.send"+=",10undefinedmethod`+='for20:Fixnuma=20;a+=10=>30 最佳答案 恐怕你不能。+=不是方法，而是语法糖。参见http://www.ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html它说Incommonwithmanyotherlanguages,Rubyhasasyntacticshortcut:a=a+2maybewrittenasa+=2.你能做的最好的事情是:

我是ruby的新手，我认为重新构建一个我用C#编写的简单聊天程序是个好主意。我正在使用Ruby2.0.0MRI(Matz的Ruby实现)。问题是我想在服务器运行时为简单的服务器命令提供I/O。这是从示例中获取的服务器。我添加了使用gets()获取输入的命令方法。我希望此方法在后台作为线程运行，但该线程正在阻塞另一个线程。require'socket'#Getsocketsfromstdlibserver=TCPServer.open(2000)#Sockettolistenonport2000defcommandsx=1whilex==1exitProgram=gets.chomp
我对如何计算通过{%assignvar=0%}赋值的变量加一完全感到困惑。这应该是最简单的任务。到目前为止，这是我尝试过的:{%assignamount=0%}{%forvariantinproduct.variants%}{%assignamount=amount+1%}{%endfor%}Amount:{{amount}}结果总是0。也许我忽略了一些明显的东西。也许有更好的方法。我想要存档的只是获取运行的迭代次数。 最佳答案 因为{{incrementamount}}将输出您的变量值并且不会影响{%assign%}定义的变量，我

我不确定这种事情是否很常见，但我一直在尝试创建只是Rails应用程序包装器的gem。我的gem将有一个生成器来创建config.ru，但Rails应用程序将位于gem的lib目录中。我需要知道如何“嵌入”Rails应用程序并对其进行配置，以便它可以在gem中运行。例如:$mygemnewprojectmygemcreatedadirectorycalled"project"withthefollowingfiles:project/config.ruproject/widgets/project/foobars/我的gem还将生成一些需要以某种方式添加到Rails的目录，以便我可以从G
