hongbin, fyi - https://github.com/docker/docker-py/issues/597

[hongbin (hongbin034)]

Thanks Dims. I will check if there is a walk-around on Magnum side. If no, then we have to wait for the version upgrade of docker.

    Use new docker exec call

    Docker-py would soon deprecated the execute method, instead
    they suggest to use exec_start and exec_create
