Ansible Training – Labs

Setup: Debian/Ubuntu Vagrant Setup

Mon, 01 Jan 0001 00:00:00 +0000

To participate in the lab you can use any 3 Linux servers of your choice. The labs are tailored for setup with CentOS/RHEL hosts. Below are instructions on how to setup the 3 required host with Vagrant on Linux. Follow the step by step guide to bootstrap the techlab environment on your OS of choice.

Debian/Ubuntu Based Systems

Info

Debian and Ubuntu ship per default with Vagrant. Depending on the version and age of the distribution Vagrant may not include support for CentOS 8 and fails during the initial setup. As such the Debian package from HashiCorp the vendor of Vagrant is utilized to ensure a frictionless lab experience.

CentOS/RHEL Based Systems

Info

On Linux we use the libvirt provider for vagrant. Using Libvirt in user session is quite troublesome: the vagrant vms fail to use the default NAT network, but in user session you can not create a new one. This is why we have to use sudo a lot in the follwing setup.

Setup: Windows Vagrant Setup

Mon, 01 Jan 0001 00:00:00 +0000

To participate in the lab you can use any 3 Linux servers of your choice. The labs are tailored for setup with CentOS/RHEL hosts. Below are instructions on how to setup the 3 required host with Vagrant on Windows. Follow the step by step guide to bootstrap the techlab environment on your OS of choice.

Warning

The following passwords are not secure and intended only to be used with local virtual machines not reachable from outside of the virtualization host.

Prerequisites

VirtualBox 6 and higher requires 64-bit Windows.

Connectivity Details

With the Windows Vagrant setup provided the three local CentOS virtual machines running under VirtualBox have the following IP addresses and credentials.

control: 192.168.122.30
node1: 192.168.122.31
node2: 192.168.122.32

user: vagrant
password: vagrant

On Windows ensure VirtualBox and Vagrant are installed. The easiest way is to use Chocolatey to install both of them.

In an administrative powershell console execute the following commands:

# install chocolatey
Set-ExecutionPolicy Bypass -Scope Process -Force;
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;
iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

# installl VirtualBox and Vagrant
choco install -y virtualbox vagrant

Open a new PowerShell console with your login account privileges and execute the following commands.
