Vagrant: Enforce provisioning order in a multi-machine environment - vagrant

Question

My Vagrantfile creates three VMs: k8s-master, ndoe-1, and node-2. How can I enforce that k8s-master is fully provisioned before the provisioning for node-1 and nod-2 starts?
Here is my Vagrantfile:
IMAGE_NAME = "generic/ubuntu1804"
N = 2
Vagrant.configure("2") do |config|
config.ssh.insert_key = false
config.vm.provider "libvirt" do |v|
v.memory = 1024
v.cpus = 2
end
config.vm.define "k8s-master" do |master|
master.vm.box = IMAGE_NAME
master.vm.network "private_network", ip: "192.168.50.10"
master.vm.hostname = "k8s-master"
master.vm.provision "ansible" do |ansible|
ansible.playbook = "kubernetes-setup/master-playbook.yml"
ansible.extra_vars = {
node_ip: "192.168.50.10",
}
ansible.compatibility_mode = "2.0"
end
end
(1..N).each do |i|
config.vm.define "node-#{i}" do |node|
node.vm.box = IMAGE_NAME
node.vm.network "private_network", ip: "192.168.50.#{i + 10}"
node.vm.hostname = "node-#{i}"
node.vm.provision "ansible" do |ansible|
ansible.playbook = "kubernetes-setup/node-playbook.yml"
ansible.extra_vars = {
node_ip: "192.168.50.#{i + 10}",
}
ansible.compatibility_mode = "2.0"
end
end
end
end
The multi-machine documentation mentions outside-in ordering, so I tried putting the for-each loop inside the k8s-master's define-block, but then the nodes are not created at all.
