I ran the command, brew services start docker-machine.
It says, "Successfully started docker-machine". But, I got error when I ran docker ps -a. Please help.

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

Same problem here. I have found that docker-machine is trying to move its HostOnly network to 192.168.99.1/24. This is outside the range VirtualBox allows on MacOS.
See https://www.virtualbox.org/manual/ch06.html#network_hostonly :
On Linux, Mac OS X and Solaris, Oracle VM VirtualBox will only allow IP addresses in the 192.168.56.0/21 range to be assigned to host-only adapters.
That range corresponds to 192.168.56.1 - 192.168.63.255.
The solution that worked for me is:
docker-machine rm default
docker-machine create -d virtualbox --virtualbox-hostonly-cidr "192.168.63.1/24" default
You're starting docker-machine as a service but not any Docker Socket.
Once you have installed docker and docker-machine with brew, you actually need to run Docker on a Linux kernel, docker binary is just the client and you cannot run Docker natively in OS X.
So first, you need to create a machine with VirtualBox where you're actually going to run Docker. For that you should do:
docker-machine create --driver virtualbox default
In case that you receive an error like:
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
That means that you don't have Virtual Box installed, so you need to cask-install it on your MacBook:
brew install virtualbox --cask
Once you have already installed VirtualBox, it's time to create a machine with the aforementioned command. You should have an output like the following:
docker-machine create --driver virtualbox default
[...]
Docker is up and running!
To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env default
But still if you run docker ps or similar it will complain that the Socket isn't running. The reason is that Docker CLI looks by default for the local daemon, so we have to explicitly tell the CLI that we want to use a different one.
For that, run the following command that will tell your CLI which machine do we actually want to use:
docker-machine env default
Next time you run docker ps or any other Docker command, it will work and run on the created default machine.
PD: Remember to stop the machine when you're not using it! For that you can just use the following command:
docker-machine stop default
Did everything before sounded like a lot of work and you just want to use Docker now without any further work?
Install it as an application and forget about docker-machine:
brew cask install docker
That's it.
I am trying to create docker machine with a virtual machine using oracle virtualbox and ubuntu server 16.04 on windows 10 pro with the following command:
$ docker-machine create -d virtualbox manager2
but process ends with this error:
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"
while VT-X is enabled (I have an intel cpu)
This helped me out to solve the same error:
docker-machine create -d virtualbox --virtualbox-memory=4096 --virtualbox-cpu-count=4 --virtualbox-disk-size=40960 --virtualbox-no-vtx-check default
I have a project in Visual Studio 2019. I want to learn Docker and try to deploy my 2 web applications in a swarm.
When i use command
"docker-machine create -d hyperv --hyperv-virtual-switch "stationext" myvm1"
Docker creates a virtual machine. I can see it in Hyper-V Manager. But this VM is with Linux.
How to create VM by command "docker-machine create" with Windows on board?

What i see in VM
I think the behavior is the expected one, don't know where did you see that you will be launching windows OS containers, boot2docker is Linux as you can see on their git:
https://github.com/boot2docker/boot2docker#readme
At the same time, you can see that this is deprecated in favor of Docker for Windows.
For running windows host on docker I think you should have a look at this:

I am trying to create a docker-machine in my windows 10 Enterprise machine.
I am creating using driver hyperv but the machine creation is failing with error Error creating machine: Error detecting OS: OS type not recognized
>>docker-machine create --driver hyperv loc-machine1
I can see the loc-machine1 under docker-machine ls
But while trying to communicate from local client docker-machine env loc-machine1 ,its throwing error
Error checking TLS connection: Error checking and/or regenerating the certs:
There was an error validating certificates for host "
[fe80::215:5dff:fe17:100c]:2376": dial tcp [fe80::215:5dff:fe17:100c]:2376:
connectex: A socket operation was attempted to an unreachable network.
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.
Tried regenerate-certs but its not working.
Docker version :- 17.03.1-ce
As described in docker troubleshooting documentation, you can try :
Regenerate certificates then restart docker host.
or
Create a new docker-machine
I have an exisiting VM with docker installed (CoreOS) and I can connect to docker with the following powershell command.
docker-machine create --driver generic --generic-ip-address=$IP --generic-ssh-key=$keyPath --generic-ssh-user=user vm
docker-machine env vm | Invoke-Expression # Set Environment Variables
Everything worked fine. I was able to build and run containers.
Then I told my build server to run the powershell script and it was running successfully. But then I lost the connection on my dev machine and got the following exception
Error checking TLS connection: Error checking and/or regenerating the certs: There was an error validating certificates for host "$IP": x509: certificate signed by unknown authority
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.
When I recreate my config with docker-machine rm vm it works again.
How can I share an SSH key to a remote docker host without recreating the docker-machine?
