Multiple EC2 instances using Vagrant - ruby

Question

I'm trying out Vagrant to provision an environment with multiple EC2 instances in AWS (using vagrant-aws plugins) and using a JSON config file for Vgrant to read from. Below is the JSON file:
macp-3:vagrant-aws sans$ cat scripts/aws.json
{
"env": "dops",
"access_key": "XXXXXXXXXXXXXXXX",
"secret_key": "hfgy5ejfkprg2432432beqo2r",
"region": "eu-west-1",
"availability_zone": "a",
"subnet_id": "subnet-0b766860",
"security_groups": [
"sg-53t48c34",
"sg-11668f7e",
"sg-4a6c8525",
"sg-75168c1e"
],
"ssh_username": "ubuntu",
"keypair": "Xdops_testKey",
"ssh_private_key": "/Users/sans/.ssh/id_rsa",
"ec2s": {
"dops-agg-001": {
"ami_id": "ami-838675f7",
"instance_type": "m3.medium",
"elastic_ip": "ture",
"tags": {
"Name": "dops-agg-001",
"Role": "sql-aggr",
"ServiceType": "database",
"NopeType": "mem_master",
"CostCentre": "QA"
}
},
"dops-nag-001": {
"ami_id": "ami-838675f7",
"instance_type": "m3.medium",
"elastic_ip": "ture",
"tags": {
"Name": "dops-nag-001",
"Role": "monitoring",
"ServiceType": "controller",
"NopeType": "nagios",
"CostCentre": "QA"
}
}
}
}
This is the Vagrantfile that I've come up with:
# -*- mode: ruby -*-
# vi: set ft=ruby :
aws_cfg = (JSON.parse(File.read("scripts/aws.json")))
Vagrant.configure("2") do |config|
config.vm.box = "dummy"
config.vm.box_url = "https://github.com/mitchellh/vagrant-aws/raw/master/dummy.box"
aws_cfg['ec2s'].each do |node|
node_name = node[0]
node_value = node[1]
# Node specific configuration
config.vm.define node_name do |config2|
ec2_tags = node_value['tags']
# Spining up EC2 instances
config2.vm.provider :aws do |ec2, override|
ec2.access_key_id = aws_cfg['access_key']
ec2.secret_access_key = aws_cfg['secret_key']
ec2.keypair_name = aws_cfg['keypair']
ec2.region = aws_cfg['region']
ec2.availability_zone = aws_cfg['region']+aws_cfg['availability_zone']
ec2.subnet_id = aws_cfg['subnet_id']
ec2.security_groups = aws_cfg['security_groups']
#
ec2.ami = node_value['ami_id']
ec2.instance_type = node_value['instance_type']
ec2.elastic_ip = node_value['elastic_ip']
#
ec2.tags = {
'Name' => ec2_tags['Name'],
'Role' => ec2_tags['Role'],
'ServiceType' => ec2_tags['ServiceType'],
'NopeType' => ec2_tags['NopeType'],
'CostCentre' => ec2_tags['CostCentre']
}
#
override.ssh.username = "ubuntu"
override.ssh.private_key_path = "/Users/sans/.ssh/id_rsa"
end
# Final Puppet provisioning
#config2.vm.provision :puppet do |ppt|
# ppt.options = "--verbose --debug"
# ppt.manifests_path = "puppet/manifests"
# ppt.manifest_file = "nodes.pp"
# ppt.module_path = "puppet/modules"
#end
end
end
end
It's working okay but trying to spin up the boxes in parallel, instead of one-by-one:
macp-3:vagrant-aws sans$ vagrant up --provider=aws
Bringing machine 'dops-agg-001' up with 'aws' provider...
Bringing machine 'dops-mon-001' up with 'aws' provider...
[fog][WARNING] Unable to load the 'unf' gem. Your AWS strings may not be properly encoded.
==> dops-mon-001: HandleBoxUrl middleware is deprecated. Use HandleBox instead.
==> dops-mon-001: This is a bug with the provider. Please contact the creator
==> dops-agg-001: HandleBoxUrl middleware is deprecated. Use HandleBox instead.
==> dops-mon-001: of the provider you use to fix this.
....
....
I believe there are some problem with looping in the Vagrantfile? Can anyone tell me what's going wring here? Best!

This question has been answered in a Google Group.
Solution:
--[no-]parallel - Bring multiple machines up in parallel if the provider supports it.
