This video is a demonstration of how to launch and scale Docker containers into an Apache Mesos cluster using Marathon. It shows how it is possible today to scale docker instances in production with Mesos. In this video you will learn:
- How to provision a Mesosphere cluster on Google Cloud Platform
- How to run Docker images in host and bridge mode
- How Mesos manages ports
- How HAProxy is used to load balance services running in Docker containers
- How to ensure there is only one of a given service on any one node
- How to constrain services to specific tagged nodes
- How to tag nodes
- How to scale up or down services in Docker containers
- How to run legacy services in the same cluster as Docker container services

We are impressed with what Docker is doing in the community. We look forward to the opportunity to help developers launch Docker containers into a production cluster.
