Running a container on all hosts

[tiagoboldt]

I would like to have a specific container running on all my Marathon hosts.

I could set the number of instances to a ridiculously high number and then set the hostname: unique constraint, but it would probably impose an unnecessary load on the cluster with continuous attempts to allocate the service while also being prone to failure if at some point the number of machines goes above the number set for instances.

Is there an optimal solution for this? Shouldn't this case be natively supported by Marathon?

interest for this request. but I don't think marathon should provide the function.

I suppose you have a service to interact with marathon restful api, then scale it depend on the number of machines scale.
