Labs are designed for learning. I learn by doing. While I can read, as they say in the local vernacular in my propinquity “Wicked Fast,” I don’t process read information to the depth that I need in order to retain it. I need to type in the code in order to learn. Here’s a technique I use to do that.
Continue readingAn earlier port hard coded the IP address and port used for MariaDB connections. I want to pull these out so I can pass them in on the command line when I create the client.

Red Hat supports installing OpenShift on OpenStack. As a Cloud SA, I need to be able to demonstrate this, and make it work for customers. As I was playing around with it, I found I could not tear down clusters due to a dependency issue with ports.

The story I tell when I explain the various offereings that Red Hat has based on Ansible follow is based on the progression of Me. Us. Them.
Me: Get my playbook working for me on my workstation. For this, I use Ansible Engine.
Us: Share my playbook with my larger team. For this, I use Ansible Tower.
Them: Make a Self service catalog for the larger organization to consume. This is where Ansible integration into other products comes in to play. I typically talk about CloudForms integration here, but Satellite and OpenShift are also capable of making use of Ansible here.
Here is how I have my local setup for doing Ansible based development. This is organized roughly around how Tower will later consume the roles and playbooks I design here.
Continue readingWhen a user requests a code review, the review is responsible for making sure that the code is tested. While the quality of the tests is a subjective matter, their presences is not; either they are there or they are not there. If they are not there, it is on the developer to explain why or why not.
Not every line of code is testable. Not every test is intelligent. But, at a minimum, a test should ensure that the code in a patch is run at least once, without an unexpected exception.
