How can I do computations on the fly within the vagrant file - ruby

How can I compute the hash on the fly within the vagrant file based on some input, for e.g. I do
# shell
$ echo "machine13" | sha256sum | cut -c1-12
2372240456c2
# vagrantfile
Vagrant.configure(2) do |config|
config.vm.hostname = "machine13"
config.vm.network "public_network", bridge: "eth0", use_dhcp_assigned_default_route: true, :mac => "2372240456c2"
end

If you just want to run a bash command and get its output to a variable in your Vagrantfile, you could use the ruby's back ticks to execute the command.
For example, your Vagrantfile:
# Vagrantfile
my_hostname = "machine12"
mac_hash = `echo #{my_hostname} | sha256sum | cut -c1-12`
Vagrant.configure(2) do |config|
config.vm.hostname = my_hostname
config.vm.network "public_network", bridge: "eth0", use_dhcp_assigned_default_route: true, :mac => mac_hash
end

Why is the default Vagrant shared folder empty?

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"

I don't want to use vagrant any more and want to build docker containers in my machine itself. How can i do that.
You can create a Dockerfile and use docker build to create an image:
http://docs.docker.com/engine/userguide/dockerimages/
once you have an image you can use run to create the container:

When i comment this line, everything goes well
config.vm.network :private_network, ip: "192.168.33.10"
But i connot access to te LMS and CMS pages (Cuz i comment this line of course)
Any suggestion will be appreciated !
Finally ! i solved it ! Here is the solution :
1- I run VBox-Win10-fix-14040.exe as Admin (See this Discussion)
2- Run the VirtualBox.exe as Admin + Compatibility with Windows 7
3- And Vagrant up :)
That's it !
Simple solution: Delete the already created (default) Host only Ethernet Adapter from VirtualBox Preferences and run sh launch.sh (if you received error while installing Mirantis Openstack package).
P.S. I don't see a reason why it shouldn't work for Vagrant as well.
for windows 7 x86, maybe your virtual box update to latest version. Try to revert back to version 4. can choose release on march or september 2014
If you are getting error similar to below while trying to setup Mirantis Openstack package on Virtualbox:
VBoxManage.exe: error: The host network interface name 'VirtualBox Host-Only Et' could not be foundVBoxManage.exe: error: The host network interface named 'VirtualBox Host-Only Et' could not be found

vagrant provision for dev and production

We started using Vagrant to setup our development environment.
Now we would like to use the same Vagrantfile also in production/staging.
When I use the same vagrantfile that contains a virtualbox provider and gce I get the 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.
Machine name: default
Active provider: virtualbox
Requested provider: google
Is there a way I can vagrant up virtualbox and gce?

The right answer is to remember that your Vagrantfile is just a Ruby program, first and foremost, and the execution of this program is to result in a datastructure that the CLI sub-commands traverse.
So, create functions that add provisioners to configuration, then call them in the "inside". For example,
def provisioner_one(config)
config.vm.provision :shell, 'echo hello'
end
Vagrant.configure('2') do |config|
# stuff here
config.vm.define 'dev' do |dev, override|
# whatever else here
provisioner_one(dev)
# other stuff here
end
# more other stuff here
end
This will DWIM.

Override Vagrant configuration settings locally (per-dev)

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']
