Basic Setup

This setup makes use of the Vagrant module, a pseudo-cookbook which is responsible for local environment provisioning using Vagrant (powered by Chef + Berkshelf under the hood).

Overview

Currently a virtual machine with the following services is created:

  • Karaf
  • Apache
  • Tomcat
  • ActiveMQ
  • MongoDb
  • Brosermob
  • Firefox
  • X environment

AET Services

All services run using default ports. For communication please use the following IP address:

  • 192.168.123.100

General Prerequisites

By default the Vagrant virtual machine needs 3 GB of RAM and 2 vCPUs, so please make sure that you have enough memory on your machine (8 GB is minimum, 16 GB is recommended though).

Installation

As the administrator execute the following commands:

  • vagrant plugin install vagrant-omnibus
  • vagrant plugin install vagrant-berkshelf
  • vagrant plugin install vagrant-hostmanager

Whenever you'd like to keep all Vagrant related data and virtual machine disks in non-standard directories please:

  • set the VAGRANT_HOME variable for the location (by default it is set to $HOME/vagrant.d).
  • update VirtualBox settings (File -> Preferences -> General) to move all disks to other directory.

Starting Virtual Machine

Once you set all the thigs described above just execute:

berks update && vagrant destroy -f && vagrant up

First Run

All the commands need to be executed when you're inside a directory that contains Vagrantfile.

Next you will need to execute:

  • berks install - downloads Chef dependencies from external sources. It acts as mvn clean install, but for Chef cookbooks.
  • vagrant up - creates a new virtual machine (the .box file will be downloaded during the first run), runs Chef inside it, sets domains and port forwarding up.

Updates

Whenever a new version is released please execute the following:

  • git pull to get the latest version of Vagrantfile.
  • berks update to update Chef dependencies.
  • vagrant provision to re-run Chef on the virtual machine.

SSH Access

To access the virtual machine via SSH please execute vagrant ssh from the same directory that contains Vagrantfile. After that please type sudo -i and press ENTER to switch to root.

If you prefer to use PuTTY, mRemote or any other connection manager, please log in as the user vagrant with the password vagrant on localhost with the port 2222. Keep in mind that the port may be different if you have more than one Vagrant machine running at the same time. You can check the current assignment by executing the vagrant ssh-config command from the directory that contains your Vagrantfile.

Useful Vagrant Commands

  • vagrant reload restarts the Vagrant machine and re-applies settings defined in Vagrantfile. It's useful whenever you've changed the port forwarding or synced folder configuration.
  • vagrant destroy -f deletes the entire virtual machine.
  • vagrant reload --provision restarts the virtual machine and re-runs Chef afterwards.
  • vagrant suspend suspends the virtual machine that is currently running.
  • vagrant resume resumes the suspended virtual machine.
  • vagrant status shows the status of the virtual machine described in Vagrantfile.
  • vagrant halt halts/turns off the virtual machine.

Port Forwarding

The local port is a port exposed on your machine. You can access services via localhost:<PORT>.

The VM port refers to the port assigned inside the Vagrant virtual machine.

Port forwarding rules can be easily changed in Vagrantfile.

Local port VM port Description
8181 8181 Karaf

Known Issues

  • When getting the following error during application deployment to the local Vagrant: 
    What went wrong: Execution failed for task ':deployDevClearCache'. > java.net.ConnectException: Connection timed out: connect
    run the ifup eth1 command on Vagrant using ssh.
