- mesosmaster:master
command: --master zk://zk:2181/mesos --zk zk://zk:2181/marathon
ports:
- 
"8080:8080"
mesosslave:
image: garland/mesosphere-docker-mesos-master:latest
ports:
- 
"5051:5051"
links:
- zookeeper:zk
- mesosmaster:master
entrypoint: mesos-slave
environment:
- MESOS_HOSTNAME=192.168.33.10
- MESOS_MASTER=zk://zk:2181/mesos
- MESOS_LOG_DIR=/var/log/mesos
- MESOS_LOGGING_LEVEL=INFO
To access the Marathon sandbox, we started the Mesos slave with
the environment variable 
MESOS_HOSTNAME=192.168.33.10
.
Replace this IP with the IP of your Docker host.
Copy this file into 
docker-compose.yml
and launch Compose:
$ ./docker-compose up -d
Recreating vagrant_zookeeper_1...
Recreating vagrant_mesosmaster_1...
Recreating vagrant_marathon_1...
Recreating vagrant_mesosslave_1...
...
Once the images have been downloaded and the containers started, you will be able
to access the Mesos UI a:5050">t 
:5050">http://:5050
. The Marathon UI will be
available on port 8080 of the same host.
Discussion
If you have cloned the online repository that comes with this book, you are only a
vagrant up
away from running Mesos with Docker:
$ git clone https://github.com/how2dock/docbook.git
$ cd dockbook/ch07/compose
$ vagrant up
$ vagrant ssh
$ cd /vagrant
$ docker-compose -f mesos.yml up -d
You can then manage the containers with the 
docker-compose
command.
