Re: Mesos Slave gets registered with lower memory than available
Related to this, is there a good way to set resource limits for the system running outside of mesos? It would be great if I could put a hard limit on memory usage for non-containerized processes (sshd, upstart, mesos-slave itself, chef, admin shell sessions, the docker daemon, etc) to make way for tighter binpacking of resources.
