containers - Sharing namespaces within Docker -

consider application app provides form of clustering allowed designated number of slaves bring together on cluster. applications b, c, , d need bring together cluster in order function properly. have application within container, while having applications b, c, , d setup within own containers. exposing ports not alternative this. should done without networking functionality there no modifying code applications a, b, c, , d. able have b, c, , d able access application within own containers. perhaps not possible, point of docker / containers, isolation, however, considering docker has --net alternative share host networking stack sure not hard implement?

if containers run on 1 machine, --link intended sort of use-case. applications have able utilize different ports configured environment variables.

there lot of activity on docker github @ moment discussing clusters, groups , networking, should expect improve native back upwards in future.

you consider 'weave', creates virtual overlay network containers, in different datacenters, can talk each other if on same ethernet switch. please note work on weave.
