Vagrant doesn't automatically launch Docker Host VM

[Andrew Rosca]

I'm trying to use the Docker provider with Vagrant per this documentation:

https://www.vagrantup.com/docs/docker/basics.html

I get the following error:

C:\vagrant-docker> vagrant up

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", "ps", "-a", "-q", "--no-trunc", {:notify=>[:stdout, :stderr]}]

Stderr: An error occurred trying to connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json?all=1: open //./pipe/docker_engine: The system cannot find the file specified.

Stdout:

I don't have Docker installed on the host VM (it's Windows 7) and instead use VirtualBox. According to the documentation (link above):

Host VM
If the system cannot run Linux containers natively, Vagrant automatically spins up a "host VM" to run Docker. This allows your Docker-based Vagrant environments to remain portable, without inconsistencies depending on the platform they are running on.

How do I get Vagrant to spin up a Docker host in VirtualBox?

My Vagrantfile looks like this:

Vagrant.configure("2") do |config|

config.vm.provider "docker" do |d|

d.build_dir = "."

end

end

Thanks!

Hello

Thanks for reporting this.

We are reviewing the documentation, and seems the documentation could get an update.

can you test as:

Vagrant.configure("2") do |config|

config.vm.provider "docker" do |d|

d.force_host_vm = true

d.build_dir = "."

end

end

Thanks

Alvaro
