Examples The first argument is the key within the yaml representing a property / field that you would like to set. Nested fields can be accessed through a dot: rpk redpanda config set redpanda.developer_mode true All values are parsed as yaml and, since yaml is a superset of json, you can also format your input as json.

You can index one past the end of an array to extend it: rpk redpanda config set redpanda.advertised_kafka_api[1] '{address: 10.0.0.1, port: 9092}' The json format can be used to set values as json: rpk redpanda config set redpanda.rpc_server '{"address":"0.0.0.0","port":33145}' --format json You may also use <key>=<value> notation for setting configuration properties: rpk redpanda config set redpanda.kafka_api[0].port=9092 Usage rpk redpanda config set <key> <value> [flags] Flags Value Type Description -h, --help - Help for set. --config string Redpanda or rpk config file; default search paths are /var/lib/redpanda/.config/rpk/rpk.yaml, $PWD/redpanda.yaml, and /etc/redpanda/redpanda.yaml. -X, --config-opt stringArray Override rpk configuration settings.
