I'm working with Kubernetes on Mesos, with Weave as an overlay network. I'm trying to get Mesos to create it's Docker containers on the Weave network, but for some reason I'm failing. I've created an /etc/mesos-slave/executor_environment_variables file on each slave that sets the DOCKER_HOST env var to the Weave socket, but Mesos doesn't seem to pick it up. I've neglected using the static Weave bridge for this as that is no longer recommended, but Mesos doesn't seem to want to cooperate, so that's my next step.
