mesos-slave停止时如何自动启动新任务实例? [英] how to auto launch new task instance when mesos-slave stopped?

问题描述

1. • 版本信息和命令行参数

1. • version Info and command line args

mesos-master & mesos-slave version 1.1.0
marathon version 1.4.3
docker server version 1.28

mesos-master的命令行参数:

mesos-master's command line args:

--zk=zk://ip1:2181,ip2:2181,ip3:2181/mesos \
--port=5050 \
--log_dir=/var/log/mesos \
--hostname=ip1 \
--quorum=2 \
--work_dir=/var/lib/mesosmaster

mesos-slave的命令行参数:

mesos-slave's command line args:

--master=zk://ip1:2181,ip2:2181,ip3:2181/mesos \
--log_dir=/var/log/mesos --containerizers=docker,mesos \
--executor_registration_timeout=10mins --hostname=ip1 \
--recovery_timeout=1mins \
--resources=ports:[25000-65000] \
--work_dir=/var/lib/mesos  

操作

1. 在马拉松Web UI中，通过docker image运行应用程序，任务状态为未知". (因为我没有添加健康检查)
2. 重新引导运行任务的计算机.
3. 现在，我以为的预期结果是该任务将被杀死，而马拉松将创建一个新任务，但是现在(见下图)

1. In marathon web UI,run a app via docker image,and task state is "Unknown". (Because I doesn't add health check)
2. reboot the machine which runs the task.
3. Now,the expected result what I thought is that the task will be killed and marathon will create a new task,but now (see below picture)

任务状态变为计划外".大约15分钟后才能杀死任务. 最后，我想要的是新任务将自动启动，而旧任务将被自动杀死(或删除或删除)

The State of Task became "Unscheduled". the the task can not be killed only after about 15mins. Finally,what I want is the new task will auto launch and the old task auto be killed ( or removed or expunged)

推荐答案

似乎您需要为任务配置unreachableStrategy.指南此处对其进行了解释.我将很快使用它，因此也将在此处发布示例.

It seems like you need to configure unreachableStrategy for your tasks. The guide here explains it. I will be playing with it soon so will post an example here as well.
