    Hello,

    Was it a warning or an error? If the worker did not join the cluster it isn't due to a newer version of docker. With constant change these sorts of mismatches often happen.

    Did the worker join the cluster?

    Hi @jperret,

    The warning you described is just informative in value, and does not cause any issues with the cluster bootstrapping process.

    Regards,
