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.

Use docker-machine ls to view the host status:

:~/docker-test-env$ docker-machine ls

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

According to the search results, it should be caused by 10-machine.conf; but the 10-machine.conf file and folder were deleted Still unable to start

Inferring that docker-machine still has some problems installing docker, we can only Manual installation

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* \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

sudo rm -rf /etc/systemd/system/docker.service.d/

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

sudo yum install -y docker-ce docker-ce-cli containerd.io

Start docker and check the docker service status
