HashiCorp/Vagrant

Getting started

Create Vagrant project, by creating Vagrantfile in your current directory

vagrant init

Add boxes (standard VMs from providers in Virtualbox, VMware or Hyper-V format)

vagrant box add hashicorp/precise64        #username: hashicorp boximage: precise64, this is preconfigured repository
#Box can be specified via URLs or local file paths, Virtualbox can only nest 32bit machines
vagrant box add --force ubuntu/14.04 https://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box
vagrant box add --force ubuntu/14.04-i386 https://cloud-images.ubuntu.com/vagrant/precise/current/precise-server-cloudimg-i386-vagrant-disk1.boxvi

Configure Vagrantfile to use the box as your base system

Vagrant.configure("2") do |config|
 config.vm.box = "ubuntu/14.04-i386"
end

Power up your Vagrant box

vagrant up

Error:

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

The error above is due to Virtualbox cannot run nested 64bit virtualbox VM. Spinning up a 64bit VM stops with an error that no 64bit CPU could be found.

Shared directory between Vagrant VM and an hypervisor provider

Vagrant VM shares a directory mounted at /vagrant with the directory on the host containing your Vagrantfile

Delete Vagrant VM

vagrant destroy

Delete downloaded Vagrant VM image file

vagrant box remove

Build in provisioning

Vagrant can run from shared location script or from inline: Vagrant file shell provisioning commands.

vi ~/git/vagrant/bootstrap.sh     #create provisioning script
   #!/usr/bin/env bash
   export http_proxy=http://username:password@proxyserver.local:8080
   export https_proxy=$http_proxy 
   apt-get update
   apt-get install -y apache2
   if ! [ -L /var/www ]; then
      rm -rf /var/www
   ln -fs /vagrant /var/www      #configures that shared directory will be Apache DocumentRoot directory
   fi

vi ~/git/vagrant/Vagrantfile   #configure Vagrant to run this shell script when setting up our machine
   Vagrant.configure("2") do |config|
      config.vm.box = "ubuntu/14.04-i386"
      #the provision line tells Vagrant to use the shell provisioner to setup the machine
      config.vm.provision :shell, path: "bootstrap.sh"
   end
 vagrant up                   #runs provisioning only once
 vagrant reload --provision   #reloads VM skipping import and runs provisioning
 vagrant ssh                  #ssh to VM
 wget -qO- 127.0.0.1          #test Apache is running on VM

Networking - port forwarding

Vagrant can forward any host(hypervisor) TCP port to guest vm specyfing in ~/git/vargant/Vagrant file

config.vm.network :forwarded_port, guest: 80, host: 4567

Reload Vagrant VM

vagrant reload

Run on the host from a web browser http://127.0.0.1:4567 to test it.
