With the spec that Angus proposed, a read/write bind mount volume is not a requirement as the configuration comes from the central data store (etcd or zookeeper).
Just pid=host and net=host are hard requirements. Nova will not work without net=host, atleast on RPM based distributions. Sam Yaple I think indicated it had worked in the past on Ubuntu, but we really want to stick with a ³all the distress² policy even for experimental repositories. I found getting neutron networking with nova vas operational inside Kubernetes to be non-viable, but I couldn¹t get very far because of the lack of net=host. Using replication controllers also didn¹t work as I would have liked because there is no way to specify "replicate to all nodes 1 copy of the pod². I¹m unclear how the kubernetes service construct would work in a world with net=host, but perhaps it is detailed in the implementation. I would recommend to pick the tech you want to work with, either mesos or kubernetes as to put all effort behind one arrow rather than two :) Regards -steve On 11/3/15, 11:25 AM, "Michal Rostecki" <[email protected]> wrote: >On 11/03/2015 04:16 PM, Jeff Peeler wrote: >> On Tue, Nov 3, 2015 at 1:44 AM, Michal Rostecki >><[email protected]> wrote: >>> Hi, >>> >>> +1 to what Steven said about Kubernetes. >>> >>> I'd like to add that these 3 things (pid=host, net=host, -v) are >>>supported >>> by Marathon, so probably it's much less problematic for us than >>>Kubernetes >>> at this moment. >> >> I don't actively track Kubernetes upstream, so this seemed like a >> natural point of reevaluation.
