Enabling GUI on Vagrant VirtualBox - undefined local variable - laravel

I'm new to vagrant/homestead, and I'm trying to debug the box that was created using vagrant up as the connection is on a timeout loop. I'm trying to enable the GUI. I've tried adding the config from the vagrant site and every variation of it to my vagrantfile:
config.vm.provider "virtualbox" do |v|
v.gui = true
end
But whenever this is in there and I run vagrant up or reload, it just returns "Message: undefined local variable or method 'config' for main:Object"
Any ideas? Thanks in advance!

Recently I had the same problem, in my case this is because I put this code outside the main vagrant config block, try to put in the proper place like in example. First line define local variable config which used inside the block:
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
// other configs
config.vm.provider "virtualbox" do |v|
v.gui = true
end
end

How to run ansible task based on the Vagrant provider

I have a vagrant job to create new VMs. Depending on the provider I pass to it, this could be created locally on Virtualbox, or on a Vsphere cluster with the vagrant-vsphere plugin.
Because of this, there are times when I want to run certain tasks on Virtualbox, and certain tasks on Vsphere. I figured the easiest way to do so would be to just pass a variable from Vagrant to ansible based on the provider. Roughly, this is what I have in my Vagrantfile so far.
$ansible_provider = ''
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.define vmconf[:name] do |vagrantconf|
vagrantconf.vm.provider :virtualbox do |vb|
$ansible_provider = "virtualbox"
end
vagrantconf.vm.provider :vsphere do |vb|
$ansible_provider = "vsphere"
end
end
config.vm.provision :ansible do |ansible|
ansible.playbook = "provision.yml"
ansible.extra_vars = { ansible_ssh_user: 'test',
ansible_provider: $ansible_provider }
end
end
I added a print statement that shows the two extra_vars and ansible_ssh_user works correctly, but ansible_provider is just blank. When I remove the first line and change it to a local variable, I get the following error:
Message: undefined local variable or method 'ansible_provider'
I haven't used ruby all that much, so I figured I'm doing something wrong there. Any help with this would be greatly appreciated.
For this specific case, I think there is an easier way of achieving what you want. Ansible creates a series of facts for each host it runs against, which includes collecting virtualisation information for guests.Try adding the following task in one of your playbooks to see what I mean:
- name: Display Virtualisation Type fact
debug:
var: ansible_virtualization_type
That should mean you don't need to pass the variable in from Vagrant. If you want to see all the facts, in the directory containing your Vagrantfile, just run (you can add '-l host' to limit to one of your VM's):
ansible -m setup all
To answer your specific question, I think this will work for you:
# In this case I don't believe you need the '$' prefix for your variables
ansible_provider = ''
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.define vmconf[:name] do |vagrantconf|
vagrantconf.vm.provider :virtualbox do |vb|
ansible_provider = "virtualbox"
end
vagrantconf.vm.provider :vsphere do |vb|
ansible_provider = "vsphere"
end
end
config.vm.provision :ansible do |ansible|
ansible.playbook = "provision.yml"
ansible.extra_vars = { ansible_ssh_user: "test",
ansible_provider: "#{ansible_provider}" }
end
end

Vagrant: Best method for Multiple Identical VMs

I would like to provision multiple VMs with Vagrant. I would like to be able to increase the number of VMs quickly and easily.
Based on my current understanding of Vagrant. The following method detailed here https://www.edureka.co/blog/10-steps-to-create-multiple-vms-using-vagrant/ seems to be the best way:
# This defines the version of vagrant
Vagrant.configure(2) do |config|
# Specifying the box we wish to use
config.vm.box = "chef/centos-6.5"
# Adding Bridged Network Adapter
config.vm.network "public_network"
# Iterating the loop for three times
(1..3).each do |i|
# Defining VM properties
config.vm.define "edureka_vm#{i}" do |node|
# Specifying the provider as VirtualBox and naming the VM's
config.vm.provider "virtualbox" do |node|
# The VM will be named as edureka_vm{i}
node.name = "edureka_vm#{i}"
end
end
end
end
So if I want to increase from 3 to 4, I just change the loop range.
Is there another method? When I was reading the docs I was hoping there would be some version of the vagrant up command that would spin up a new unique instance.
Environment Variables of Vagrant is your best bet. Define something like this in your Vagrantfile.
myVMs = ENV['NODES'] || 1
Where NODES is an environment variable. You can use this in the following way.
NODES=4 vagrant up
This will update the myVMs variable in your Vagrantfile and spawn 4 VMs. You do not need to open your Vagrantfile and update it. But note, this will be for this session alone.If you want to save the value of the NODES, then you might have to add it to your ~/.profile in Linux or environment variables in windows.
Hope this helps.

Multi-machine Vagrant project not provisioning as per docs

I’ve trying to set up a multi-machine Vagrant project. According to the docs (https://www.vagrantup.com/docs/multi-machine/), provisioning is “outside in”, meaning any top-level provisioning scripts are executed before provisioning scripts in individual machine blocks.
The project contains a Laravel project, and a Symfony project. My Vagrantfile looks like this:
require "json"
require "yaml"
confDir = $confDir ||= File.expand_path("vendor/laravel/homestead", File.dirname(__FILE__))
homesteadYamlPath = "web/Homestead.yaml"
homesteadJsonPath = "web/Homestead.json"
afterScriptPath = "web/after.sh"
aliasesPath = "web/aliases"
require File.expand_path(confDir + "/scripts/homestead.rb")
Vagrant.configure(2) do |config|
config.vm.provision "shell", path: "init.sh"
config.vm.define "web" do |web|
web.ssh.forward_x11 = true
if File.exists? aliasesPath then
web.vm.provision "file", source: aliasesPath, destination: "~/.bash_aliases"
end
if File.exists? homesteadYamlPath then
Homestead.configure(web, YAML::load(File.read(homesteadYamlPath)))
elsif File.exists? homesteadJsonPath then
Homestead.configure(web, JSON.parse(File.read(homesteadJsonPath)))
end
if File.exists? afterScriptPath then
web.vm.provision "shell", path: afterScriptPath
end
end
config.vm.define "api" do |api|
api.vm.box = "ubuntu/trusty64"
api.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--memory", "2048"]
end
api.vm.network "private_network", ip: "10.1.1.34"
api.vm.network "forwarded_port", guest: 80, host: 8001
api.vm.network "forwarded_port", guest: 3306, host: 33061
api.vm.network "forwarded_port", guest: 9200, host: 9201
api.vm.synced_folder "api", "/var/www/api"
api.vm.provision "shell", path: "api/provision.sh"
end
end
I have a block (web) for the Laravel project, where I’ve copied the contents of the Homestead-based Vagrantfile, and an api block that uses the “standard” Vagrant configuration.
To bootstrap the projects, I created a simple shell script (init.sh) that simply clones the Git repositories into git-ignored directories. Given the documentation says configuration works outside-in, I’d therefore expect that script to run, and then the machine-specific blocks, but this doesn’t seem to be happening. Instead, on vagrant up, I receive the following error:
There are errors in the configuration of this machine. Please fix the following errors and try again:
vm:
* A box must be specified.
It seems it’s still trying to provision the individual machines, before running the shell script. I know the shell script isn’t getting called as I added an echo statement to it. Instead, the terminal just outputs the following:
Bringing machine 'web' up with 'virtualbox' provider...
Bringing machine 'api' up with 'virtualbox' provider...
So how can I get Vagrant to run my shell script first? I think it’s failing because the web group is checking if my web/Homestead.yaml file exists and if so, use the values in there for configuring (including the box name), but as my shell script hasn’t been ran and hasn’t cloned the repository that file does not exist, so there is no box specified, which Vagrant complains about.
The issue is that you do not define a box for the web machine. You need to either define the box in the outer space like
config.vm.box = "ubuntu/trusty64"
if you plan to use the same box/OS for both machines or define in the web scope
web.vm.box = "another box"
EDIT
Using the provision property will run the script in the VM, which is not what you want here, as you want the script to run on your host. (and because it runs in the VM, it needs the VM to be booted first)
Vagrantfile is just a simple ruby script, so you could add your script or even an execution to it (from ruby call), a potential issue I could see is that you cannot guarantee the execution and specially that the execution of your init script will be complete before vagrant does it things on the VM.
A possibility is to use the vagrant trigger plugin and execute your shell script before the up event
config.trigger.before :up do
info "Dumping the database before destroying the VM..."
run "init.sh"
end
Running it this way, vagrant will wait for the script to be executed before it runs its part of the up command.
You would need to do some check in your script to make sure it runs only when needed, otherwise, it will run everytime you start the machine (invoking vagrant up), e.g. you could make a check on the presence of the yaml file

Updated Vagrantfile but still getting warning that my Vagrantfile is outdated

I have updated my Vagrantfile to this:
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.define :ceph do |ceph|
ceph.vm.box = "big-ceph"
ceph.vm.network :private_network, ip: "192.168.251.100"
ceph.vm.hostname = "ceph"
end
config.vm.define :client do |client|
client.vm.box = "hashicorp/precise64"
client.vm.hostname = "ceph-client"
client.vm.provision :shell, path: "setup/ceph.sh"
client.vm.network :private_network, ip: "192.168.251.101"
end
end
but I am still getting this warning message whenever I vagrant up my virtual machines.
calvin % vagrant reload ceph && vagrant reload client
There were warnings and/or errors while loading your Vagrantfile
for the machine 'ceph'.
Your Vagrantfile was written for an earlier version of Vagrant,
and while Vagrant does the best it can to remain backwards
compatible, there are some cases where things have changed
significantly enough to warrant a message. These messages are
shown below.
Warnings:
* `config.vm.customize` calls are VirtualBox-specific. If you're
using any other provider, you'll have to use config.vm.provider in a
v2 configuration block.
Any idea why?
Ok, I figured it out. This 3rd party ceph box that I am using comes with its own Vagrantfile which overrides my Vagrantfile and the included box Vagrantfile (which is located in ~/.vagrant.d/boxes/big-ceph) still contains
config.vm.customize ["modifyvm", :id, "--nictype1", "virtio"]
Comment that out and I no longer see the annoying warning.

Using Vagrant to manage development and production environments?

How are people handling simple automation (with puppet) for dev / prod environments with vagrant (ideally from the same vagrantfile)?
Use case I'm trying to solve
I would love to spin up the the production machine with vagrant if it isn't created.
I would love to reload nginx or apache confs on production with vagrant if they were tweaked in the puppet files for my dev environment.
The Problem
When you call vagrant up with a provider like AWS or Digital Ocean, it becomes the active provider and you can't switch. You get this error:
An active machine was found with a different provider. Vagrant
currently allows each machine to be brought up with only a single
provider at a time. A future version will remove this limitation.
Until then, please destroy the existing machine to up with a new
provider.
It seems the answer it to destroy, but I just need to switch. I don't want to destroy.
I would love to be able to say
vagrant up prod
or
vagrant reload prod
and then a simple vagrant up would fall back to the default machine.
This syntax is similar to how multiple machines work, but I don't want to spin up a dev and production environment when I just call vagrant up (which is the default behavior).
Should I be looking at packer as part of the workflow? I watched the whole talk at puppetconf 2013 on Mitchell's talk on Multi-Provider http://puppetlabs.com/presentations/multi-provider-vagrant-aws-vmware-and-more
I'm still not seeing a solution for my problem.
UPDATE 9/27/13
In case anybody else is fighting this idea, this article cleared up a lot of questions I had.
http://pretengineer.com/post/packer-vagrant-infra
As for workaround, you should define config.vm.define (as suggested here), in order to support multiple providers.
Please find the following configuration posted by #kzap as example:
Vagrant.configure("2") do |config|
# Store the current version of Vagrant for use in conditionals when dealing
# with possible backward compatible issues.
vagrant_version = Vagrant::VERSION.sub(/^v/, '')
# Configuration options for the VirtualBox provider.
def configure_vbox_provider(config, name, ip, memory = 2048, cpus = 1)
config.vm.provider :virtualbox do |v, override|
# override box url
override.vm.box = "ubuntu/trusty64"
# configure host-only network
override.vm.hostname = "#{name}.dev"
override.vm.network :private_network, id: "vvv_primary", ip: ip
v.customize ["modifyvm", :id,
"--memory", memory,
"--cpus", cpus,
"--name", name,
"--natdnshostresolver1", "on",
"--natdnsproxy1", "on"
]
end
end
default_provider = "virtualbox"
supported_providers = %w(virtualbox rackspace aws managed)
active_provider = ENV['VAGRANT_ACTIVE_PROVIDER'] # it'd be better to get this from the CLI --provider option
supported_providers.each do |provider|
next unless (active_provider.nil? && provider == default_provider) || active_provider == provider
#
# VM per provider
#
config.vm.define :"sample-#{provider}" do | sample_web_config |
case provider
when "virtualbox"
configure_vbox_provider(sample_web_config, "examine-web", "192.168.50.1")
when "aws"
configure_aws_provider(sample_web_config)
when "managed"
configure_managed_provider(sample_web_config, "1.2.3.4")
when "rackspace"
configure_rackspace_provider(sample_web_config)
end
end
end
Or the following example posted at gist by #maxlinc:
# -*- mode: ruby -*-
# vi: set ft=ruby :
# Vagrantfile API/syntax version. Don't touch unless you know what you're doing!
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "dummy"
config.vm.provider :rackspace do |rs|
rs.username = ENV['RAX_USERNAME']
rs.api_key = ENV['RAX_API_KEY']
rs.rackspace_region = :ord
end
supported_providers = %w(virtualbox rackspace)
active_provider = ENV['VAGRANT_ACTIVE_PROVIDER'] # it'd be better to get this from the CLI --provider option
supported_providers.each do |provider|
next unless active_provider.nil? || active_provider == provider
config.vm.define "exact_name_#{provider}" do |box|
box.vm.provider :rackspace do |rs|
rs.flavor = '1 GB Performance'
rs.image = 'Ubuntu 14.04 LTS (Trusty Tahr) (PVHVM)'
end
end
config.vm.define "regex_#{provider}" do |box|
box.vm.provider :rackspace do |rs|

rs.flavor = 'performance1-1'
rs.image = '547a46bd-d913-4bf7-ac35-2f24f25f1b7a'
end
end
end
end
Not an ideal solution, but what about using git branches? My thinking is that it could be conceptually similar to using heroku, where you might have a master, staging, and production versions (since they're usually different remotes).
In this case you start off the prod branch with the small edit to the Vagrantfile to name the VM a little differently. Then you should be able to merge all changes from dev with the prod branch as they occur. So your workflow would look like:
$ git checkout prod
$ vagrant up
$ git checkout master
... make changes to puppet ...
$ git checkout prod
$ git merge master
$ vagrant reload
$ git checkout master
You could script and alias these so you end up with
$ start_production
$ reload_production
Here is a simple way of dynamically changing the 'default' machine name depending on the specified --provider from the command line, so they won't conflict between the different providers:
require 'getoptlong'
opts = GetoptLong.new(
[ '--provider', GetoptLong::OPTIONAL_ARGUMENT ],
[ '--vm-name', GetoptLong::OPTIONAL_ARGUMENT ]
)
provider=ENV['PROVIDER'] || 'virtualbox'
vm_name=ENV['VM_NAME'] || 'default'
opts.each do |opt, arg|
case opt
when '--provider'
provider=arg
when '--vm-name'
vm_name=arg
end
end
Vagrant.configure(2) do |config|
# HERE you are dynamically changing the machine name to prevent conflict.
config.vm.define "mt-#{provider}-#{vm_name}"
# Below sections are just examples, not relevant.
config.vm.provider "virtualbox" do |vm|
vm.name = "test.local"
vm.network "private_network", ip: "192.168.22.22"
vm.customize ['modifyvm', :id, '--natdnshostresolver1', 'on']
config.vm.box = "ubuntu/wily64"
end
config.vm.provider :aws do |aws, override|
aws.aws_profile = "testing"
aws.instance_type = "m3.medium"
aws.ami = "ami-7747d01e"
config.vm.box = "testing"
end
end
Example usage:
VM_NAME=dev PROVIDER=virtualbox vagrant up --provider=virtualbox
VM_NAME=uat PROVIDER=aws vagrant up --provider=aws
VM_NAME=test PROVIDER=aws vagrant up --provider=aws
VM_NAME=prod PROVIDER=aws vagrant up --provider=aws
VM_NAME=uat PROVIDER=aws vagrant destroy -f
VM_NAME=test PROVIDER=aws vagrant status
See also: Multiple provisioners in a single vagrant file?
what I came up with to work with this scenario is to manage 2 distincts .vagrant folder.
Note: most of the other answers deal with setting up multi-provider assuming you will run dev and prod on different provider, in most cases this might be true but you can definitely have cases where you have same provider for dev and prod. Lets say you're using aws and you want to use dev and prod as ec2 instance it will be the same provider.
Say you want to manage dev and prod instances, potentially using different providers (but could also very well be on the same provider) so you'll do:
set up dev instance with normal vagrant up --provider <dev_provider>.
This will create a dev VM that you can manage
back up the .vagrant folder created in your project directory and rename it like .vagrant.dev
set up prod instance with your provider of choice vagrant up --provider <prod_provider>. This now creates your prod VM
back up the newly .vagrant folder created in your project directory and rename it like .vagrant.prod
now, depending if you want to work on dev or prod, you'll rename the .vagrant.dev or .vagrant.prod directory as .vagrant and vagrant will operate the right VM.
I did not come up with a script as mainly the most of the time I work with dev and very few times I need to switch to the other provider. but I dont think it will be too hard to read the parameter from CLI and make the renaming more dynamic.
