[*] The cp-kafka image includes Community Version of Kafka. The cp-enterprise-kafka image includes everything in the cp-kafka image and adds confluent-rebalancer (ADB). The cp-server image includes additional commercial features that are only part of the confluent-server package. The cp-enterprise-kafka image will be deprecated in a future version and will be replaced by cp-server.

[**] The cp-kafka-connect and cp-ksqldb-server images contain Confluent monitoring interceptors. The monitoring interceptors enable connectors and SQL queries to collect the metrics that can be visualized in Confluent Control Center. The Connect image includes Control Center in its entirety while the ksqlDB Server image just includes the monitoring interceptors. No explicit license is required when using the Connect or the ksqlDB Server image on their own.

Confluent Platform image tags

The Confluent Platform Docker images are tagged as follows.

<cp_version>-<image_release_number>-<os_type>

<image_release_number> is incremented when an updated image needs to be uploaded for the same <cp-version>.

Additional tags are applied to the image of the default OS type:

  • To identify the image as being the default image for a given release.

    <cp_version>

  • To identify the most recent version of the image of the default OS type.

    latest

For the supported OS types in Confluent Platform 6.2, see Supported Versions for Confluent Docker Images.

For example, for Confluent Platform 6.2.15 images with RHEL UBI 8 being the only supported and default OS, the available RHEL UBI 8 cp-base-new image tags are:

6.2.15-1-ubi8
6.2.15
