How to run command block in Vagrantfile only once. Try to use if case, but without success.
Vagrantfile:
# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
$hosts = {
"node-1" => { memory: 1024, cpus: 2 },
"node-2" => { memory: 4096, cpus: 2 }
}
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
$hosts.each_with_index do |(hostname, parameters), index|
config.vm.define vm_name = hostname do |vm_config|
vm_config.vm.hostname = hostname
config.vm.provision "shell", inline: "echo index=#{index}"
if index == 0
config.vm.provision "shell", path: "./bootstrap-scripts/node-1.sh"
end
end
end
end
Console result:
==> node-1: Importing base box 'generic/ubuntu1804'...
...
==> node-1: Running provisioner: shell...
node-1: Running: inline script
node-1: index=0
==> node-2: Importing base box 'generic/ubuntu1804'...

==> node-2: Running provisioner: shell...
node-2: Running: inline script
node-2: index=0
==> node-2: Running provisioner: shell...
node-2: Running: inline script
node-2: index=1
The goal is to run "./bootstrap-scripts/control.sh" script for the first machine only.
From the vagrant documentation:
The inner portion of multi-machine definitions and provider overrides are lazy-loaded. This can cause issues if you change the value of a variable used within the configs
...
The inner behaviour of each_with_index probably trigger the documented gotcha, that's why your node-2 loop through both indexes. So try using the node name in your if instead.
Also you need to use vm_config not config is you want provisioner to apply for each node.

My issue is that when I run this vagrantfile, I receive an error that states the following: default: Warning: Authentication failure. Retrying... and if I run in debug mode I just see a bunch of timeouts..
All that I am trying to do is rather than create a "vagrant" user, I want to create a user that is the same as the user on the host machine by using #{ENV['USER']} and have the user immediately be able to run vagrant ssh and if their host user is test.user, then the guest user will be test.user..
vagrant ssh-config was:
Host default
HostName 127.0.0.1
User aaron.west
Port 2200
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile /Users/aaron.west/.ssh/id_rsa
IdentityFile /Users/aaron.west/.ssh/id_rsa
LogLevel FATAL
all help is appreciated :)
I believe you'll have to create a new user on your Vagrant machine. As per the docs for the ssh.username setting, it doesn't sound like that setting actually creates a user. It only helps you to tell Vagrant what user to connect as, if the box was made with a username other than vagrant.
You probably need to shell out to useradd during provisioning.
The /vagrant directory is empty. It should contain the workspace where my Vagrantfile is located. I can cd /vagrant, but it's empty.

This happens when vagrant can't modify /etc/fstab and tries to mount the current working directory from the host. Make sure it has permissions to mount the directory.
Run this on the Vagrant guest VM, then logout.
$ sudo /etc/init.d/vboxadd setup
Run this on the host.
$ sudo vagrant reload
$ vagrant ssh
This issue happened to me after manually rebooting the VM (i.e. sudo reboot).
Restarting the machine from the host solved the problem for me:
$ vagrant halt
$ vagrant up
you need to define below line in the vagrantfile, . means current directory
config.vm.synced_folder ".", "/vagrant"

Similar to this question: Passing variable to a shell script provisioner in vagrant
I want to pass variables to a shell script provisioner but I want to set these variables on the command line when I call the provisioner. Is this possible?
This is what I would try - I guess there are possibilities as Vagrantfile is a ruby script, you can use most of ruby possibilities
Be careful though as vagrant might need to check for variables, for example when doing vagrant up arg1 arg2, it expects arg1 and arg2 to be machine names defined in Vagrantfile and will raise an error as it cannot find it
So you would need to pass those variables like
vagrant --arg1 --arg2 up
To read them you could
# -*- mode: ruby -*-
# vi: set ft=ruby :
v1 = ARGV[0]
v2 = ARGV[1]
array_arg = [v1, v2]
Vagrant.configure("2") do |config|
blabla config
array_arg.each do |arg|
config.vm.provision "shell", run: "always" do |s|
s.inline = "echo $1"
s.args = arg
end
end
end
for example, the execution would give
fhenri#machine:~/project$ vagrant --arg1 --arg2 up
. . . . .
==> default: Running provisioner: shell...
default: Running: inline script
==> default: stdin: is not a tty
==> default: --arg1
==> default: Running provisioner: shell...
default: Running: inline script
==> default: stdin: is not a tty
==> default: --arg2
In your Vagrantfile, add the following -
{
"PROVISION_PARAMS" => "some_default_values",
}.each { |key, value| ENV[key] = value if ENV[key] == nil }
These arguments can now be passed to shell script provisioner in the following way -
config.vm.provision :shell, privileged: true, run: "always",
:path => "../../scripts/script.ps1",
:args => ENV['PROVISION_PARAMS']
You can now provide command line arguments to this script in the following manner -
$ PROVISION_PARAMS=' param1 param2 "param 3" ' vagrant provision
And the script will take default values if these parameters are not specified.
I'd like the question to be answered in general, but to illustrate it, here's a use case:
I'm using Vagrant for a simple LMAP project. I use standalone Puppet for provisioning. Now, there might be some developers who sit behind a proxy and they would need some additional configuration to be made to the VM. I have things working on the Puppet side: I can pass the proxy IP (if any) as a fact to puppet in the Vagrantfile and Puppet reacts accordingly if it's set.
The only issue I have is: how can developers specify/override this setting for their development environment without having to change the Vagrantfile (which is under version control and must remain dev-environment-neutral)?
If would be awesome if people could override some Vagrant settings in a file called e.g. Vagrantfile.local, which I would exclude via .gitignore.
Since a Vagrantfile is just Ruby, I tried the following:
# Also load per-dev custom vagrant config
custom_vagrantfile = 'Vagrantfile.local'
load custom_vagrantfile if File.exist?(custom_vagrantfile)
The file inclusion basically works, but it looks like in the included file, I'm not in the same Vagrant context anymore...
Vagrant::Config.run do |config|
config.vm.provision :puppet do |puppet|
puppet.facter = { "proxy" => "proxy.host:80" }
end
end
... also "resets" all other puppet config values I made in the main Vagrantfile, which makes me think I'm heading in the wrong direction here. I should note that I'm a total noob at Ruby ;)
Can anyone give me a hint or even a working solution for how per-dev customization could be done here in general?
The Vagrantfile is just Ruby, so YAML is another option.
For example, in the Vagrantfile I do this:
# -*- mode: ruby -*-
# vi: set ft=ruby :
require 'yaml'
settings = YAML.load_file 'vagrant.yml'
db_ip_address = settings['db']['ip_address']
api_ip_address = settings['api']['ip_address']
Vagrant.configure("2") do |config|
config.vm.box = "ffuenf/ubuntu-13.10-server-amd64"
config.vm.box_url = "https://vagrantcloud.com/ffuenf/ubuntu-13.10-server-amd64/version/4/provider/virtualbox.box"
config.vm.define "db" do |db|
db.vm.synced_folder settings['db']['artifacts_dir']['host'], settings['db']['artifacts_dir']['guest']
db.vm.network "private_network", ip: db_ip_address
... other stuff ...
end
config.vm.define "api" do |api|
api.vm.synced_folder settings['api']['artifacts_dir']['host'], settings['api']['artifacts_dir']['guest']
api.vm.network "private_network", ip: api_ip_address
api.vm.network "forwarded_port", guest: settings['api']['forwarded_port']['guest'], host: settings['api']['forwarded_port']['host']
end
end
Then I have a vagrant.yml file (I just made up the name; you can use whatever name you like) for the developer-specific configuration:
db:
ip_address: 192.168.4.14
artifacts_dir:
host: /Users/willie/myapp/db-scripts
guest: /opt/myapp/db
api:
ip_address: 192.168.4.15
forwarded_port:
host: 9080
guest: 8080
artifacts_dir:
host: /Users/willie/myapp/artifacts
guest: /opt/myapp/api
I would suggest using environment variables to dynamically change the behavior of the Vagrantfile without editing the file itself.
To give a real world example, here's how you could use an Ubuntu base box by default but have an environment variable define an alternative Linux distribution:
if ENV['OPERATINGSYSTEM']
if ENV['OPERATINGSYSTEM'].downcase == 'redhat'
os_name = 'centos'
config.vm.box = 'centos'
config.vm.box_url = 'https://dl.dropbox.com/u/7225008/Vagrant/CentOS-6.3-x86_64-minimal.box'
else
raise(Exception, "undefined operatingsystem: #{ENV['OPERATINGSYSTEM']}")
end
else
os_name = 'precise64'
config.vm.box = 'precise64'
config.vm.box_url = 'http://files.vagrantup.com/precise64.box'
end
This example comes from https://github.com/puppetlabs/puppetlabs-openstack_dev_env
If you are prepared to define settings that are applied to all your vagrant boxes it's worth noting that, "Vagrant actually loads a series of Vagrantfiles, merging the settings as it goes." (ref https://docs.vagrantup.com/v2/vagrantfile/)
So I have the following defined in ~/.vagrant.d/Vagrantfile to increase the amount of RAM for my Vagrant boxes:
Vagrant.configure(2) do |config|
config.vm.provider "virtualbox" do |vb|
vb.memory = 2048
end
end
Here's an idea. It may be "ugly" and "wrong", but, at least, it works :)
# file2.rb, this is your per-dev configuration file
puts "included external file which uses outer var: #{foo}"
# file1.rb, this would be your Vagrantfile
puts 'first'
foo = 'bar'
external = File.read 'file2.rb'
eval external
puts 'second'
Let's run that
$ ruby file1.rb
first
included external file which uses outer var: bar
second
Adapting to your example, file2.rb would contain only usage of config without defining it (config will be provided from outer context)
config.vm.provision :puppet do |puppet|
puppet.facter = { "proxy" => "proxy.host:80" }
end
And your Vagrant file may look like this:
Vagrant::Config.run do |config|
external = File.read 'Vagrantfile.local'
eval external
# proceed with general settings here
config.vm.provision :puppet do |puppet|
puppet.facter = { "proxy" => "proxy.host:80" }
end
end
Update (another, "data-driven" approach)
# Vagranfile.local
config_values[:puppet][:facter][:proxy] = 'proxy.host:80'
# Vargantfile
Vagrant::Config.run do |config|
config_values = {
puppet: {
facter: {
proxy: nil
},
manifests_file: 'my_manifest.pp'
}
}
external = File.read 'Vagrantfile.local'
eval external # this should overwrite proxy config
# proceed with general settings here
config.vm.provision :puppet do |puppet|
if config_values[:puppet][:facter][:proxy]
puppet.facter = { "proxy" => config_values[:puppet][:facter][:proxy] }
end
puppet.manifests_file = config_values[:puppet][:manifests_file]
end
end
I believe that's the exact use case that Nugrant plugin was created to solve. It allows each of your devs to have a .vagrantuser (which is a .gitignore-ed file) in YAML specifying custom configuration values then reference these values with ease in Vagrantfile.
In your case, a proxied developer would have their .vagrantuser file looking like this:
proxy: 'proxy.host:80'
And your Vagrantfile would look like this (pseudo code, I don't really know ruby):
Vagrant::Config.run do |config|
config.vm.provision :puppet do |puppet|
if config.user.has_key?('proxy')
puppet.facter = { "proxy" => config.user.proxy }
end
end
end
You should bundle a sample/reference vagrantuser (i.e. vagrantuser.example) file for your devs to copy and adjust to their environment.
To extend on #Willie Wheeler 's answer. My setup is:
Root
|-- defaults.yml
|-- env.yml
|-- Vagrantfile
Vagrantfile
# Load local env config
require 'yaml'
dir = File.dirname(File.expand_path(__FILE__))
# defaults
settings = YAML::load_file("#{dir}/defaults.yml")
if File.exist?("#{dir}/env.yml")
env_settings = YAML::load_file("#{dir}/env.yml")
settings.merge!(env_settings)
end
...
# Customize the amount of memory on the VM:
vb.memory = settings["vb"]["memory"]
defaults.yml
vb:
memory: 1024
env.yml
vb:
memory: 204
This will merge whatever defaults you have with your per-dev config. Also it is clear to developers what values they can actually change
Consider using vagrant-proxyconf plugin. It allows to set proxy for all Vagrant VMs globally.
Another solution is to run external shell script during provisioning. I use separate config.vm.provision section at the beginning of Vagrantfile to do it:
# reset: true below is needed to reset the connection to the VM so that new
# environment variables set in /etc/environment will be picked up in next
# provisioning steps
config.vm.provision "shell", reset: true, inline: <<-SHELL
if [ -f /vagrant/Vagrantfile-settings.sh ]
then
/vagrant/Vagrantfile-settings.sh
fi
SHELL
Then just put a Vagrantfile-settings.sh file next to Vagrantfile, add it to .gitignore (or whatever) and put any script inside, for example to set proxy for interactive terminal, all daemons and docker containers:
# Proxy for interactive terminals
echo "http_proxy=http://PROXY_ADDRESS:PROXY_PORT" >> /etc/environment
echo "https_proxy=http://PROXY_ADDRESS:PROXY_PORT" >> /etc/environment
echo "no_proxy=127.0.0.1,localhost" >> /etc/environment
# Proxy for daemons (e.g. Docker deamon - used to pull images, apt - run from default daily cron job)
mkdir /etc/systemd/system.conf.d
echo [Manager] > /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"http_proxy=PROXY_ADDRESS:PROXY_PORT\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"https_proxy=PROXY_ADDRESS:PROXY_PORT\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"no_proxy=127.0.0.1,localhost\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "# Docker requires upper-case http proxy environment variables..." >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"HTTP_PROXY=http://PROXY_ADDRESS:PROXY_PORT2\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"HTTPS_PROXY=http://PROXY_ADDRESS:PROXY_PORT\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
echo "DefaultEnvironment=\"NO_PROXY=127.0.0.1,localhost\"" >> /etc/systemd/system.conf.d/01-http-proxy.conf
# Proxy for docker containers started with `docker run`
mkdir /home/vagrant/.docker
cat <<EOF > /home/vagrant/.docker/config.json
{
"proxies": {
"default": {
"httpProxy": "http:/PROXY_ADDRESS:PROXY_PORT",
"httpsProxy": "http://PROXY_ADDRESS:PROXY_PORT",
"noProxy": "127.0.0.1,localhost"
}
}
}
EOF
chown -R vagrant:vagrant /home/vagrant/.docker
You can load the settings from YAML file. This is demonstrated in Drupal VM as below:
# Use config.yml for basic VM configuration.
require 'yaml'
dir = File.dirname(File.expand_path(__FILE__))
if !File.exist?("#{dir}/config.yml")
raise 'Configuration file not found! Please copy example.config.yml to config.yml and try again.'
end
vconfig = YAML::load_file("#{dir}/config.yml")
So then you can create config.yml like:
vagrant_box: geerlingguy/ubuntu1404
vagrant_user: vagrant
vagrant_ip: 192.168.88.88
and in Vagrantfile you can use variables as:
config.vm.box = vconfig['vagrant_box']
config.vm.network "private_network", ip: vconfig['vagrant_ip']
