Running a Marathon Task on every active slave

["David J. Palaitis" <da...@gmail.com>]

I'd like to have Marathon keep a single, running instance of my command on
every active slave in the cluster. Is it possible?

If you are OK with a fixed number of slaves. You could set the number of
instances equal to the number of slaves, and then set the constraints of the
job to: "constraints": [[ "hostname", "UNIQUE" ]].

Hey David,
  Yes"ish" from my understanding with the host name constraint(to restrict 1
per host) you can do this but you will need prior knowledge of the amount of
slaves. Here is my reference
https://mesosphere.github.io/marathon/docs/constraints.html

Hope that helps!
