body: <p>Hi I just install docker i open the cmd and create a default docker machine:</p>
  
  <pre><code>C:\git&gt;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
  
  C:\git&gt;docker-machine ls
  NAME      ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER    ERRORS

  C:\git&gt;docker-machine env default
  SET DOCKER_TLS_VERIFY=1
  SET DOCKER_HOST=tcp://192.168.99.100:2376
  SET DOCKER_CERT_PATH=C:\Users\NGT1IMB\.docker\machine\machines\default
  SET DOCKER_MACHINE_NAME=default
  REM Run this command to configure your shell:
  REM     @FOR /f "tokens=*" %i IN ('docker-machine env default') DO @%i

  <p>And then i got this error when trying to follow the tutorial:</p>
  
  <pre><code>C:\git&gt;docker run hello-world
  docker: An error occurred trying to connect: Post https://192.168.99.100:2376/v1.23/containers/create: x509: cannot vali
  date certificate for 192.168.99.100 because it doesn't contain any IP SANs.
  See 'docker run --help'.

  <p>Any reply is much appreciated.</p>
