rpk cluster info

Request broker metadata information.

The Kafka protocol’s metadata contains information about brokers, topics, and the cluster as a whole.

This command only runs if specific sections of metadata are requested. There are currently three sections: the cluster, the list of brokers, and the topics. If no section is specified, this defaults to printing all sections.

If the topic section is requested, all topics are requested by default unless some are manually specified as arguments. Expanded per-partition information can be printed with the -d flag, and internal topics can be printed with the -i flag.

In the broker section, the controller node is suffixed with *.

Using --detailed augments the broker section with Admin API metadata: the number of cores per broker, membership status, liveness, version, and broker UUID (when reported by the Admin API). It also prints a per-broker DISK SPACE section.

Using --include-decommissioned additionally lists decommissioned nodes by their UUID at the end of the broker table.

If the Admin API is unreachable when --detailed or --include-decommissioned is set, the basic broker view is still printed; pass -v to see the underlying error.

Using this command with --format json/yaml implies that all sections are included.
