Ansible playbook - golang vm

Spin up a golang development environment with a MEAN stack on the side.

This Vagrant and Virtualbox based Ansible playbook sets up a Go development environment.

For persistence, two alternatives are included:

• MongoDB as part of a complete MEAN stack (Mongodb, Node + Express suitable for back-end for Angular SPAs) together with a sample AngularJS application run on a NodeJS server.
• MySql server

Instructions

• Install VirtualBox and Vagrant (make sure Vagrant is version 1.6.5 or later)

• Install Ansible

• Clone this project to a folder where you keep your VMs

• First execute vagrant box list to check if ubuntu/trusty64 is already on your laptop or desktop host system. If it isn't download the box with vagrant box add ubuntu/trusty64.

• If you receive messages to the effect that the box has a newer version, follow the instructions:

==> default: A newer version of the box 'ubuntu/trusty64' is available! You currently
==> default: have version '20150609.0.10'. The latest is version '20151015.0.0'. Run
==> default: `vagrant box update` to update.

• On the cammand-line in that folder, type vagrant up

• The process will take a while, on my 4GB RAM MacBook Pro it took about 20+ minutes initially. But remember that's just the first time, once you have it provisioned it starts up again very quickly. A large part of the initial slowness is the one-time provisioning via Ansible of the MEAN components, especially MongoDB.

• Check out your new vm on the command line with vagrant ssh

• Associate http://golang-dev/ (or any other name you'd like) with local machine IP specified in the Vagrantfile (192.168.46.100 initially) by including the following line in /etc/hosts:

  192.168.46.100 golang-dev

• Within the guest VM box, if you do your work in, say, /vagrant/dev/project01 then in the VM dir ./dev/project01 you can access the files with your favorite editor or IDE or else edit via ssh remoting.

• The MEAN stack example app is at /vagrant/dev/recipe-js

• If you create and run a node.js app on port 3000, you can access it in your browser by pointing it at http://golang-dev:3000.

Vagrantfile

• Box used: Ubuntu 14.04 64-bit (Trusty)
• Virtualbox settings:
• memory 1024
• IP 192.168.76.103

Playbook tasks (see provisioning/playbook.yml)

• Installs build-essential, git and curl packages from Apt together with golang and mysql-server (including python-mysqldb in order to automate tasks with mysql).
• The firewall is optionally disabled since the purpose is local development (comment out to omit).
• MySql is started up, the test database removed and a golang-dev database created, with user root without password.
• MongoDB installation:
• Imports MongoDB's public GPG key.
• Adds MongoDB's Apt source.
• Installs MongoDB
• Node.js installation:
• Sets up NodeSource for Ubuntu.
• Installs NodeJS.
• Installs the following globally with npm install -g:
  • Installs Gulp .
  • Installs Bower.
  • Installs Karma.
