rpk container start

Start a local container cluster.

This command uses Docker to initiate a local container cluster. Use the --nodes (or the shorthand version -n) flag to specify the number of brokers.

The initial broker starts on default ports, with subsequent brokers' ports offset by 1000. You can use the following flags to specify listener ports:

  • --kafka-ports

  • --admin-ports

  • --rpc-ports

  • --schema-registry-ports

  • --proxy-ports

Each flag accepts a comma-separated list of ports for your listeners. Use the --any-port flag to let rpk randomly select an available port on the host machine.

In case of IP address pool conflict, you may specify a custom subnet and gateway using the --subnet and --gateway flags respectively.

By default, this command uses the redpandadata/redpanda:latest Redpanda container image. You can specify a container image by using the --image flag. See the available images at Docker Hub.

Usage

rpk container start [flags]

Examples

Start a three-broker cluster:

rpk container start -n 3

Start a single-broker cluster, selecting random ports for every listener:

rpk container start --any-port

Start a 3-broker cluster, selecting the seed kafka and console port only:

rpk container start --kafka-ports 9092 --console-port 8080

Start a three-broker cluster, specifying the Admin API port for each broker:

rpk container start --admin-ports 9644,9645,9646
