DCOS Slaves :添加放置约束

Question

我已经在下面的链接(https://dcos.io/docs/1.10/installing/custom/advanced/)的指导下安装了DCOS集群。

现在，DCOS集群启动并运行。我想为托管DCOS集群顶部的应用程序添加“放置约束”。

我在/opt/mesosphere/etc/mesos-MESOS_ATTRIBUTES=SPACE:RACK1-common文件中添加了参数(MESOS_ATTRIBUTES=SPACE:RACK1)。添加之后，我无法再次启动dcos-mesos-slave服务

你能告诉我如何使用上面的DCOS安装方法来解决这个问题吗？

etc # cat mesos-slave-common

应该将Mesos属性添加到/var/lib/dcos/mesos-slave-common，而不是/opt/mesosphere/etc/mesos-slave-common。请注意，您可能需要在第一次创建此文件。

步骤

停止从机:将属性systemctl stop dcos-mesos-slave

• Add to /var/lib/dcos/mesos-slave-common

• Clean out旧的活动执行器：rm -f /var/lib/mesos/slave/meta/slaves/latest

• Start

• slave：systemctl restart dcos-mesos-slave
