unable to run OpenFOAM docker image

I'm trying to use the OpenFOAM docker image. I installed everything correctly and when I try to run OpenFOAM_Start I get the error:

Started machines may have new IP addresses. You may need to re-run the docker-machine env command.

Error response from daemon: No such container: of_1712

Error: failed to start containers: of_1712

Error: No such container: of_1712

Stopping "default"...

Machine "default" was stopped.

Then I ran docker-machine env command and I got the error:

Error checking TLS connection: Host is not running

I would appreciate if you could help me know what is the problem and how I can solve it.

P.S. Hopefully this is not off-topic. Please let me know if I should ask this question in a different stackexchange.

Solution

I found the solution but I'm still not sure what the error above mean. As indicated in the OpenFOAM installation guide, right after installation of the docker image you should run the:

"OF_Create_Env" shortcut on the Desktop. A shell will open and close automatically, completing setup of the user working environment. This step is mandatory only on the first occasion of OpenFOAM for Windows installation.

Then you can run OpenFOAM_Start again and it just works.
