Я попробовал следующую команду для создания машины Docker на хосте CentOS 7.7.1908 

docker-machine create --driver generic --generic-ip-address X.X.X.X --generic-ssh-key ~/.ssh/id_rsa machineName

    Running pre-create checks...
    Creating machine...
    (h164) Importing SSH key...
    Waiting for machine to be running, this may take a few minutes...
    Detecting operating system of created instance...
    Waiting for SSH to be available...
    Detecting the provisioner...
    Provisioning with centos...
    Error creating machine: Error running provisioning: something went wrong running an SSH command
    command : sudo systemctl -f restart docker
    err     : exit status 1
    output  : Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Я прикрепил две приведенные ниже команды, указанные ниже. 

systemctl status docker.service

Журнал содержит «kernel: overlayfs: не удалось разрешить», я попытался найти исправление для этого, но безрезультатно. 

journalctl -xe

Похоже, это связано с fsoverlay, глядя на docs Я вижу "CentOS, использующий ядро ​​версии 3.10.0-514 или выше".

Просмотр версии ядра моей установки
