The goal of this repo is to experiment with running Weave Net inside of minimesos. This repo contains a Dockerfile for a custom minimesos image and a minimesosFile that uses this image.
$ cd docker; ./build.sh
$ cd ..; minimesos up
$ docker ps -a
$ docker run -it $MINIMESOS_AGENT_CONTAINER_ID sh
(Inside minimesos agent container)
# Run the contents of runtask.sh using the IP of the minimesos master
When you run this a Mesos container is started but a network cannot be created:
mesos-execute --networks=weave --resources='cpus:1;mem:265' --name=webserver --command='while true ; do echo -e "HTTP/1.1 200 OK\n\n $(date)" | nc -l -p 1500 ; done' --master=172.17.0.4:5050

The problem here is that there is no weave bridge and when creating it inside the container nsenter is missing.
$ ./weave --local create-bridge
ERROR: nsenter utility missing. Please install it.
root@92caf5e095f6:/script# apt-get install nsenter
