Confluent Platform Docker Images

  • Confluent Platform Docker Images will no longer ship with Yum/Apt configuration that allowed users to update running Confluent Platform containers to the next Confluent Platform release. Confluent recommends upgrading Confluent Platform service components running in containers by replacing the running container with the next Confluent Platform released Docker image and using Docker volumes to persist data between upgrades.
  • Confluent Platform Docker images formerly shipped with world writable data and configuration directories (chmod a+w). Those permissions are now removed, and adjustments made to make those directories writable from the image’s appuser USER.
  • Confluent Platform Docker images are now built with yum --nodocs ... to prevent installing Red Hat Documentation. This slims down the images slightly. Confluent documentation from Confluent packages are still installed.
