Mesos in Docker

Mesosphere builds Apache Mesos into several Docker containers:

Dockerfiles: https://github.com/mesosphere/docker-containers/tree/master/mesos

Other Mesosphere Packages: https://mesosphere.com/downloads/

Machines

The recommended way to run Mesos in Docker is to run each master and slave container on their own machine, with their own IP.

Networking

Host networking (--net=host) is recommended. While Mesos can operate in bridge networking, it is slower and has many caveats and configuration complexities.

Example: Local Dev/Test

For development or experimentation, one Master and one Slave can be run on the same machine.

The following commands set up a local development environment with Exhibitor/Zookeeper, Mesos-Master, and Mesos-Slave, using host networking. This is not fit for production.

Caveats:

  • Docker containers launched by the Mesos-Slave will continue running on the host after the Mesos-Slave container has been stopped.
  • Docker volumes created by the Mesos-Slave will be relative to the host, not the Mesos-Slave container.

Launch Exhibitor (Zookeeper)

Exhibitor Configuration Reference

docker run -d --net=host netflixoss/exhibitor:1.5.2

Launch Mesos-Master
