Question:
Error with Docker daemon for docker installation on Fiware cloud

Description:
I am new with the Fiware and docker technologies so I need some help.

I am following the instructions from this link http://simple-docker-hosting-on-fiware-cloud.readthedocs.io/en/v1.0/manuals/install in order to create a docker-host machine on Fiware cloud but when I run the following command:

docker-machine create -d openstack --openstack-flavor-id="2" --openstack-image-name="base_ubuntu_14.04" --openstack-net-name="node-int-net-01" --openstack-floatingip-pool="public-ext-net-01" --openstack-sec-groups="docker-sg" --openstack-ssh-user "ubuntu" docker-host

I receive the following error:

Error creating machine: Error running provisioning: Unable to verify the Docker daemon is listening: Maximum number of retries (10) exceeded

Although, I can see the instance of the docker-host machine on Fiware cloud, but when I run the following command:

eval "$(docker-machine env docker-host)"

the following error comes up:

Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "147.27.60.136:2376": dial tcp 147.27.60.136:2376: connectex: No connection could be made because the target machine actively refused it.
You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which might stop running containers.**

I also tried to regenerate the certificates:

docker-machine regenerate-certs docker-host

but I received the following error:

Error getting SSH command to check if the daemon is up: ssh command error:
command : sudo docker version
err : exit status 1

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?**

What am I doing wrong?

I use docker community edition for windows 10.
