Using Docker Swarm and Mesos

Swarm comes with a built-in scheduler that works with the swarm manager to schedule container resources. You can completly replace the built-in scheduler with a 3rd party scheduler. For example, you can replace it with the Mesos scheduler as described here.

When using Docker Swarm and Mesos, you use the Docker client to ask the swarm manager to schedule containers. The swarm manager then schedules those containers on a Mesos cluster.

Prerequisites

Each node in your swarm must run a Mesos slave. The slave must be capable of starting tasks in a Docker Container using the --containerizer=docker option.

You need to configure two TCP ports on the slave. One port to listen for the swarm manager, for example 2375. And a second TCP port to listen for the Mesos master, for example 3375.

Start the Docker Swarm manager

If you use a single Mesos master:

docker run -d -p <swarm_port>:2375 -p 3375:3375 swarm manage -c mesos-experimental --cluster-opt mesos.address=<public_machine_ip> --cluster-opt mesos.port=3375 <mesos_master_ip>:<mesos_master:port>

If you use multiple Mesos masters:

docker run -d -p <swarm_port>:2375 -p 3375:3375 swarm manage -c mesos-experimental --cluster-opt mesos.address=<public_machine_ip> --cluster-opt mesos.port=3375 zk://<mesos_masters_url>

Once the manager is running, check your configuration by running docker info as follows:

docker -H tcp://<manager_ip:manager_port> info

For example, if you run the manager locally on your machine:
