Let’s say you’re testing a setup with multiple web servers. Last login: Sun Oct 4 01:46:18 2015 from Preventing some machines from booting Then the above command will work: $ vagrant ssh Last login: Sun Oct 4 01:46:18 2015 from get around this limitation (I SSH into my web server WAY more than my DB server) you can specify a default VM when you define the virtual machine: config.vm.define "web", primary: true do |web| Welcome to your Vagrant-built virtual machine.
#VAGRANT PROVISION UPGRADE#
Run 'do-release-upgrade' to upgrade to it. This command requires a specific VM name to target in a multi-VM environment. There are a few commands that will require you to enter the VMs name but Vagrant is helpful enough to tell you when that happens: $ vagrant ssh => web: Attempting graceful shutdown of VM.īut you can also run commands on a single VM by adding the name of the VM after the command: $ vagrant halt db => db: Attempting graceful shutdown of VM. The VMs are all listedĪbove with their current state. This environment represents multiple VMs. The cool thing is that vagrant automatically runs most commands on all of the VMs in the Vagrantfile: $ vagrant status
#VAGRANT PROVISION INSTALL#
I remember a couple years ago when it took hours to manually creating the VMs in VirtualBox and install Linux (sigh). The second is that we were able to create two VMs with just a single command. The first thing to point out here is that “default” text is gone and in it’s place is the “web” and “db” names that we defined in the Vagrantfile above. Now when we run vagrant up we see some very different results: $ vagrant upīringing machine 'web' up with 'virtualbox' provider.īringing machine 'db' up with 'virtualbox' provider. One is the “web” VM and it provides web services (duh) and the other is db and it provides database services (duh again). This Vagrant file specifies two different VMs. At Zimco we have a Google Doc spreadsheet that keeps track of all our Vagrantfile VMs so we don’t need to worry about conflicts (that way we can have multiple projects running at the same time in case we need to jump over and fix a quick bug or eight).įor our example our initial (see below for the final) Vagrantfile looks like this: nfigure("2") do |config| You absolutely need to make sure you give them a unique hostname, IP address, and name setting so there aren’t conflicts. Vagrant allows us to define more virtual machines by wrapping them in blocks like the following: config.vm.define " " do || => default: Destroying VM and associated drives.
If we don’t destroy this box before we do the next step we’ll leave it running and taking up disk space so we’re going to destroy it: $ vagrant destroyĭefault: Are you sure you want to destroy the 'default' VM? y If you’ve worked with Vagrant before you’ve seen this a MILLION times but I want to draw your attention to the “default” text that shows up over and over again. default: /vagrant => /Users/scottkeckwarren/blah => default: Importing base box 'precise64'. Then to make sure everything is working correctly: $ vagrant upīringing machine 'default' up with 'virtualbox' provider. I’m going to use the basic configuration we created in Getting Started With Vagrant stripped down to the very basics: nfigure("2") do |config|Ĭonfig.vm.network :private_network, ip: "192.168.56.101" Because of this we need to work with multiple VMs in the same Vagrant file which isn’t covered by most tutorials. We’re starting to work on scaling STAGES from a single server to multiple servers so I’m using Vagrant as the test bed for this process. You can do this with a pre-script (prepare), the reload plugin and a post script (cleanup).One of the things I love about Vagrant is how it allows you to quickly create a VM that is very close to your production environment (or better yet EXACTLY like it). This can happen because a specific command could require certain files not to be in use or for example the vagrant user not to be logged in. Suppose you want to have a specific command executed only once after a reboot. Tip 5: Execute a command once after a reboot Inspiration from the Oracle provided Vagrantfiles here. This way you don’t have to first install the plugins before you can use the Vagrantfile. System('vagrant plugin install vagrant-reload') Unless Vagrant.has_plugin?("vagrant-reload") System('vagrant plugin install vagrant-vbguest') Puts 'Installing vagrant-vbguest Plugin.' Unless Vagrant.has_plugin?("vagrant-vbguest")
System('vagrant plugin install vagrant-disksize') Puts 'Installing vagrant-disksize Plugin.' Unless Vagrant.has_plugin?("vagrant-disksize")
