Vagrantfile with multiple vm and providers - amazon-web-services

Question

I am trying to write a Vagrantfile with multiple machines backed up by multiple providers. I specifically want to be able to spawn more than one of those machines in one go. Basically I want to run the command:
vagrant up vb_vm aws_vm
I am aware of the --provider flag, but this would apply to all machines being spawned, so not applicable in my case.
This is my (very trimmed down but still valid) Vagrantfile:
Vagrant.configure(2) do |config|
config.vm.define 'vb_vm' do |vb_vm|
vb_vm.vm.box='ubuntu/trusty64' # from hashicorp
vb_vm.vm.provider :virtualbox do |v|
end
end
config.vm.define 'aws_vm' do |aws_vm|
aws_vm.vm.box = "aws/dummy"
aws_vm.vm.box_url = 'https://github.com/mitchellh/vagrant-aws/raw/master/dummy.box'
aws_vm.vm.provider :aws do |a, override|
a.access_key_id = 'something'
a.secret_access_key = 'something'
a.ami='something'
end
end
end
A vagrant box list shows that the boxes used for each definitions are of the right type:
aws/dummy (aws, 0)
ubuntu/trusty64 (virtualbox, 20150928.0.0)
But a vagrant status gives me (note that I do have the lxc plugin available, which became the default)
Current machine states:
aws_vm not created (aws)
vb_vm not created (lxc)
So this shows that spawning multiple machine with multiple provider is indeed possible, but the choice of provider is wrong.
I am aware of the tricks to set up the default provider, but this only makes things worse (virtualbox used everywhere, aws not used at all...)
I am aware of old stackoverflow questions as well, but they are related to a much older version of Vagrant.
So the question is: how do I make sure that each box defined uses its proper provider?

Answer 1

The trick will be to create the VM with their own provider.
example: I've defined a quick Vagrantfile (minimized) with boxes for each provider
Vagrant.configure(2) do |config|
config.vm.define "db" do |db|
db.vm.box = "..."
db.vm.hostname = "db"
end
config.vm.define "app", primary: true do |app|
app.vm.box = "..."
app.vm.hostname = "app"
app.ssh.forward_agent = true
app.ssh.forward_x11 = true
app.vm.provider "vmware_fusion" do |vm|
vm.vmx["memsize"] = "4096"
end
end
end
I create each VM separately
fhenri#machine:~/project/examples/vagrant/multimachine$ vagrant up db --provider=virtualbox
Bringing machine 'db' up with 'virtualbox' provider...
....
fhenri#machine:~/project/examples/vagrant/multimachine$ vagrant up app
Bringing machine 'app' up with 'vmware_fusion' provider...
....
then I halt everything and next time I do vagrant up
fhenri#machine:~/project/examples/vagrant/multimachine$ vagrant up
Bringing machine 'db' up with 'virtualbox' provider...
Bringing machine 'app' up with 'vmware_fusion' provider...
and status looks good
fhenri#machine:~/project/examples/vagrant/multimachine$ vagrant status
Current machine states:
db running (virtualbox)
app running (vmware_fusion)
This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.
