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.
