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.
