Docker Image Reference

The Confluent Platform images are available on Docker Hub. The source files for the images are available on the GitHub repos. From GitHub you can extend and rebuild the images and upload them to your own DockerHub repository.

The following table lists the available images and the Confluent software packages that they contain. Some images are identified as `cp-enterprise-${component_name}`. These images include proprietary components that must be licensed from Confluent when deployed.

Note

The Kafka Connect and ksqlDB Server images are labeled as “Enterprise” simply because they 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 5.5, see Supported Versions for Confluent Docker Images.

For example, for Confluent Platform 5.5 images with Debian 8 being the default OS, the available tags are as follow.

  • The RHEL UBI 8 cp-base-new image tag:

    5.5.0-1-ubi8
    
  • The Debian 8 cp-base-new image tags:

    5.5.0-1-deb8
    5.5.0
    latest
