DC/OS (mesos/marathon) how set time to start killed instance of aplication

Question

I have install DC/OS (3master and 7slave server - all Centos7)

I saw problem - when one of slave server shut down - mesos/marathon start killed instance of application after 5 minutes.

For example - I run in mesos/marathon 8 instance simple web application. When I shut down or deactivate network interface of one slave server marathon show that some instancje are killed. From this moment mesos/marathon wait 5 minutes and start killed instance to another online slave server.

My question is - how can I change this time? 5 minutes is to long. I read documentation of DC/OS but I can't find variable responsible for this.

I will be very thankful for your help.

You can have a at the Marathon command-line flags. Based on your description, I guess the default for either task_launch_timeout or scale_apps_interval could be responsible for this.

I'm unsure though if this can be configured on the fly, or during installation in DC/OS. I saw that there's a quite recent enhancement request to Make Marathon flags passable via environment variables.
