cannot connect to port 2376 when using 2019-box context

[antoinell]

Thanks for creating this useful repository. I tried to use it today on Mac in order to be able to spin up a Windows Docker container and had the following problem

git clone https://github.com/StefanScherer/windows-docker-machine
brew install --cask vagrant  
brew install --cask virtualbox  
vagrant up --provider virtualbox 2019-box
docker context use 2019-box
docker version

I ran a netstat command and here was the output

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

  https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

  VAGRANT_DISABLE_VBOXSYMLINKCREATE=1

or on a per folder basis within the Vagrantfile:

  config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false

It looks like it is a networking issue and I would need to use this tutorial https://jekhokie.github.io/linux/vagrant/networking/2020/07/25/vagrant-network-connectivity-and-routes.html in order to add a route to the subnet used by vagrant.
