The charm currently runs both on Juju 2.9 LTS and Juju 3.1, although 2.9 is now deprecated and support on this Juju version may be discontinued in future charm release. We therefore advise new deployments to be carried out on Juju 3.

For migration of the deployment from a Juju 2.9 to a 3.x controller, please get in touch with the product team.

The minimum supported Juju versions are:

2.9.32+ (although deprecated).
3.1.6+ (due to issues with Juju secrets in previous versions, see #1 and #2)

Minimum requirements

For production environments, it is recommended to deploy at least five nodes for Apache ZooKeeper and three for Apache Kafka. While the following requirements are meant to be for production, the charm can be deployed in much smaller environments.

64GB of RAM
24 cores
12 storage devices
10 GbE card

Supported architectures

The charm is based on the charmed-kafka snap, which is currently available for amd64 only! The architecture arm64 support is planned. Please contact us if you are interested in new architecture!
