Hello,
This slave is running in a 2gb ram VM (KVM), inside a docker, with other
dockers (zookeeper, mesos master and marathon) just it. All the elements
almost empty because it isn't production ready, just a test environment.
But the slave are recognized as 999 Mem, almost half of what it is.
Is it right?
The mesos-slave alocates others dockers, I dont understand if my mesos
slave should take all the available ram recognized and it will split this
ram in the dockers this mesos-slave will launch, or the ram that the slave
uses need to be lower than is available to live memery for the other
dockers, or what?
Thank you.
