rpk cluster config

Interact with cluster configuration properties.

Cluster properties are Redpanda settings that apply to all brokers in the cluster. These are separate from broker properties, which apply to only that broker and are set with rpk redpanda config.

Use the edit subcommand to interactively modify the cluster configuration, or export and import to write the configuration to a file that can be edited and read back later.

These commands take an optional --all flag to include all properties such as low-level tunables (for example, internal buffer sizes) that do not usually need to be changed during normal operations. These properties generally require some expertise to set safely, so if in doubt, avoid using --all.

Modified properties are propagated immediately to all brokers. Use the status subcommand to verify that all brokers are up to date and identify any settings which were rejected by a broker; for example, if the broker is running a different Redpanda version that does not recognize certain properties.
