Installing Ansible AWX on CentOS 8

AWX is a web application that sits on top of Ansible, providing a “user interface, REST API and task engine for Ansible”. Since AWX can integrate into vRealize Automation, I decided to stand up an instance of it in my home lab.

Installing Ansible

Since I was starting with a complete fresh CentOS 8 system, the first thing I needed to do was install Ansible. Unfortunately, Ansible is not available in the default repos configured in CentOS 8, so the repo for it needs to be added first.

# Add EPEL repo
yum install epel-release
# Install Ansible
yum install ansible
# Confirm installation and version
ansible --version

An Introduction to Packer

Recently I had an extended discussion about Packer with a fellow IT professional and recalled some material I had previously put together about Packer. Looking back at this material, I thought an expanded version of it might be worth writing up, with Windows Sysadmins in mind (since that’s my background).

What Problem Does It Solve?

I feel sometimes it’s best to start with what problem we are trying to solve, to help provide context for how a tool might be useful. A number of user stories can capture the problems Packer can solve.

As an Infrastructure Engineer, I want standardised templates for multiple platforms, so that template management is easier and consistent

This talks about a task that many infrastructure engineers and systems administrators have had to perform – regularly updating virtual machine templates on vCenter and other platforms. In some cases, this can be very onerous, so we want an easier way. In other cases, where the templates aren’t maintained, it can lead to increased deployment times (because the “Install Windows Updates” task during the SCCM task sequence takes longer and longer).

As a Security Engineer, I want our infrastructure across multiple platforms to adhere to the same security standards, so that my organisation’s data and reputation are protected

vRealize Automation 8.1 New Features Walkthrough

VMware announced the general availability of vRealize Automation 8.1 a couple of weeks ago. This update includes a wide range of new features and capabilities. Some of these items restore functionality that was lost in transitioning from 7.x to 8.x (such as Approval Policies).

Governance and Policy

Version 8.1 adds some new items under Governance and Policy. Some of these include Approval Policy, limits on resources and view-only roles.

Approval Policy

Approval Policies have been expanded to be more in line with the functionality of what was in 7.x. In one of my first impressions posts about version 8.0, I noted there was only 2 policy types (Lease and Day 2 Actions). There is now a third option called simply Approval Policy.
