How to solve the problem that docker-machine cannot start?
Centos7 docker-machine deploys docker host and the docker service fails to start
Background:
Plans to use Centos7 Core as docker host to build tests The platform has only 4 hosts and uses the Swarm solution.
Environment:
| Host Name | System | IP Address | Pre-work |
| docker-host1 | CentOS7 Core | xxx.xxx.xxx.80 |
Update the yum source, use aliyun mirror, update to the latest status Configure the user used by docker-machine, sudo password-free |
| docker-host2 | CentOS7 Core | xxx.xxx.xxx.81 |
Update yum source, use aliyun image, update to the latest status Configure docker-machine to use User, sudo password-free |
| docker-host3 | CentOS7 Core | xxx.xxx.xxx.82 |
Update yum source, use aliyun mirror, update to the latest status Configure the user used by docker-machine, sudo password-free |
| docker- host4 | CentOS7 Core | xxx.xxx.xxx.83 |
Update yum source, use aliyun mirror, update to the latest status Configuration The user used by docker-machine, sudo password-free |
| desktop | ubuntu-18.04lts | Configuration-free Log in to docker-host with the secret key |
Installation:
Install docker-machine on the working desktop (Ubuntu) host, you can Refer to https://docs.docker.com/machine/install-machine/
First install docker-host1:
docker-machine --debug create --driver generic - -generic-ip-address=xxx.xxx.xxx.80 --generic-ssh-key=/home/sleeber/.ssh/id_rsa --generic-ssh-port=22 --generic-ssh-user=wntime docker -host1
The final output of the installation shows that the docker service cannot be started:
sudo systemctl -f start docker SSH cmd err, output: exit status 1: Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. Error creating machine: Error running provisioning: something went wrong running an SSH command command : sudo systemctl -f start 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. notifying bugsnag: [Error creating machine: Error running provisioning: something went wrong running an SSH command command : sudo systemctl -f start 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. ]
Use docker-machine ls to view the host status:
:~/docker-test-env$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS docker-host1 - generic Running tcp://xxx.xxx.xxx.80:2376 Unknown Unable to query docker version: Cannot connect to the docker engine endpoint
SSH to the docker-host1 host , manually start the docker service
sudo systemctl start docker Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
Follow the prompts to check the status

Note: After uninstalling docker, you need to manually delete the /etc/systemd/system/docker.service.d/ folder, otherwise the newly installed docker will not start.
Uninstall the existing docker and reinstall it
sudo yum remove docker* \
