Vagrant Lab for Postgres


Since a few days ago I’ve played (wink, wink) with Play, Lagom and Reactive Systems, I’ve found in the need of trying Some Scala  and implement a REST API to access a Postgres Database, so instead of downloading, installing and configuring a database in my local machine I’ve felt tempted to use Vagrant instead.

Vagrant you say?

Vagrant is a tool for building and managing virtual machine environments in a single workflow. This tools “packages” our special box which is a small VM. A remarkable aspect is Vagrant relies on “providers” for virtualization. In this case, we’ll proceed first to install both Vagrant AND Virtualbox.

The beauty of Vagrant is that several boxes with preconfigured OSs, tools and services are ready to be implemented. Just search here for a Vagrant box of your needs.

Prerequisites:

  • Vagrant.
  • VirtualBox
sudo apt install virtualbox-qt
sudo apt install vagrant

Let’s get to it!

Get Postgres Vagrant box.

Open a Terminal. Create a directory in which you will download and place your Vagrant Machine.

The previous image comprises the following actions we have performed:

  1. Create a Postgres_Vagrant directory
  2. Download our Vagrant box.
  3. Open Vagranfile for this box.

Uncomment the following line of Vagrantfile

 config.vm.network "private_network", ip: "192.168.33.10"

Add

 config.vm.network "forwarded_port", guest: 5432, host: 5432, host_ip: "127.0.0.1"

Save and close the Vagrantfile. Go back to your terminal and execute

vagrant up

This command will start the vm for this exercise.

Now we open VirtualBox and effectively our vm is ready.

That’s all! Now we can focus our effort on building our REST API to access a database, but that’s for another day).

Edit!

Since I’m now in Russia, the Postgresql locale was set to “ru_RU.UTF-8”, but it’s necessary to change it to support locale to match my language “en_US.UTF-8”.

Change it like this

11_change_locale

Thanks faqforge!
