I don't know all the details, but I guess, depending upon the exact interface, it might be possible to have a C++ wrapper around a non-C++ containerizer module. In a very naive approach, one simply fork/execs the "external" non-C++ containerizer script/program. > > it might require recompiling (parts of) Mesos, some other things? > > > No. With modules, you don't have to. > > Let me know if you have any further questions! > > - Jie > > On Thu, Oct 8, 2015 at 10:44 AM, Alex Glikson <glik...@il.ibm.com> wrote: > > > Actually we have been thinking to implement our own containerizer, and > the > > option to use ECP seemed attractive. > > Can you, please, elaborate on the implications of having our own > > containerizer without ECP?
