**To create a custom Amazon MSK configuration**

The following ``create-configuration`` example creates a custom MSK configuration with the server properties that are specified in the input file. ::

    aws kafka create-configuration \
        --name "CustomConfiguration" \
        --description "Topic autocreation enabled; Apache ZooKeeper timeout 2000 ms; Log rolling 604800000 ms." \
        --kafka-versions "2.2.1" \
        --server-properties fileb://configuration.txt

Contents of ``configuration.txt``::

    auto.create.topics.enable = true
    zookeeper.connection.timeout.ms = 2000
    log.roll.ms = 604800000

This command produces no output.
Output::
