windows 10 + cygwin
dockertoolbox ( docker-machine )
lets create the workspace to spinoff vagrant with docker provider
lets create two files here
1. DockerHostVagrantfile
2. Vagrantfile
DockerHostVagrantfile
now to use this above VM, as a Docker Host instead of a default adding two lines to the a.vm.provider block in the original Vagrantfile
configuring a custom docker host , we can specify custom forwarded ports
This can be done by adding 1 line in DockerHostVagrantfile
config.vm.network “forwarded_port”,
guest: 8080, host: 8080
$ vagrant upCommand: ["docker", "version", {:notify=>[:stdout, :stderr]}]
Stderr: error during connect: Get https://192.168.99.108:2376/v1.40/version: read tcp 192.168.43.101:52719->192.168.99.108:2376: wsarecv: An exis
ting connection was forcibly closed by the remote host.
this is the error i got, when trying to do vagrant up
this was solved by starting DockerToolBox, thats where 192.168.99.108 is coming from ( default doker host created from docker-machine )
Bringing machine 'nginx_demo' up with 'docker' provider...

A Docker command executed by Vagrant didn't complete successfully!
The command run along with the output from the command is shown
below.
Command: ["docker", "run", "--name", "nginx_demo", "-d", "-p", "80:80", "-v", "//d/vagrant/second_example/ubuntu:/vagrant",
"nginx", {:notify=>[:stdout, :stderr]}]
Stderr: Unable to find image 'nginx:latest' locally
C:\Program Files\Docker Toolbox/docker.EXE: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while wa
iting for connection (Client.Timeout exceeded while awaiting headers).
See 'C:\Program Files\Docker Toolbox/docker.EXE run --help'.again i encountered this above error, this was basically due to proxy setup which was already there ( in my case i had to remove the proxy, as i was connected to my wifi )
after this the container started successfully on my docker-host ( dockertoolbox )
$ vagrant up

==> nginx_demo: Provisioners will not be run since container doesn't support SSH.the above error is because:
1. we are running docker as a provider ,not VM as a provider.
2. vagrant flow is broken as you cannot ssh into docker container.
solution for the above is to run the command using “vagrant docker-run” .
status of the provider can be checked using the following command
$ vagrant global-statusid name provider state directory
