Docker and Orchestration Tools ¶

DC/OS¶

Confluent has partnered with Mesosphere to provide DC/OS packaging for the Confluent Platform. This has been tested, evaluated, and successfully deployed with several customers, but there are still some scenarios that require non-standard configurations. Please contact Confluent Support if you have plans to deploy on top of DC/OS.
DC/OS Versions 1.7, 1.8, and 1.9 have been evaluated successfully with Confluent Platform.
All Confluent services except the core broker and ZooKeeper services are deployed as Marathon-managed Docker containers. There is minimal variation in that support across DC/OS versions.
There are two separate frameworks for the core broker service:
- Framework version 1 (explicit versions range from 1.0.0 through 1.1.9 between April 2016 and May 2017). This framework supports Confluent Platform 3.0.1 through 3.2.1.
- Framework version 2 (released as beta in May 2017). This framework supports Confluent versions 3.2.0 and later.

For more information, see the Mesosphere DC/OS documentation.

Docker¶

Optional: Docker version 1.11 or later. This is required if you are installing Confluent Platform by using the Docker images.
