Roll Your Own Operator with Ansible

Deploying and managing an application on Kubernetes can be as simple as writing some Ansible! An Operator is a controller service that actively manages the full lifecycle of an application on Kubernetes. A mature Operator can deploy, upgrade, backup, repair, scale, and reconfigure an application that it manages. The Operator SDK makes it easier than ever to make your own operator, simply by writing or re-using Ansible roles.

In this session you will learn:
How to define and deploy your application on Kubernetes using Ansible.
How to create a Kubernetes Operator for your application using Ansible.
How to use the Operator SDK to make an operator that defines some behaviors in Ansible and others in native Go code.

Getting started with DevOps

Being one of the hottest buzzwords within IT for over almost a decade, DevOps is said to be the holy grail for increasing the speed of software development and delivery. A huge amount of Open Source Software tools support the DevOps philosophy and help to speed up things even more, but just deploying a bunch of tools and say “we are now working DevOps” is not the most efficient way in most situations.

The presentation will cover the following topics:
- In short: what is DevOps?
- What are major pitfalls and risks?
- Embracing change instead of fighting it
- What knowledge and skills do I need?
- What Open Source tools can I use?

Automating On-Call Duties with Ansible Tower

I will talk about how we automated the on-call procedure for the operations team in IT at Red Hat.

In this session the attendee will learn how we implemented Ansible, Ansible Tower, Nagios, Puppet, and Jive to automate the on-call procedure for Red Hat IT and help the oncall team be able to focus on other work items outside of pages. I will go into detail on our infrastructure setup and disaster recovery setup we have for Ansible Tower in IT. Also, I will talk about how this got multiple teams in IT interested in using Ansible Tower/Ansible for automating daily tasks after seeing this implementation in action. Implementation with Nagios and Ansible Tower did not exist before this. We have open sourced the script we created so others may use the script and contribute to it.

Incubating Continuous Delivery

Getting teams towards Continuous Delivery is a complex transformation. Not only the process and tooling needs to change, but the teams' mindset needs to be completely rebuilt from scratch.
In this talk, let me share with you the journey towards achieving CD within my current company. I have never thought that it is going to be an easy task to tackle, but some of the things I have stumbled upon were totally unexpected, others much harder to chew than originally anticipated.
Even though we are still far away from our final destination, I believe there are already some lessons learned and aha moments worth sharing. Attending this session should help you to make your journey towards CD a bit more pleasant by being aware of the obvious as well as the not-so-obvious bullets to dodge.

Ansible Plugins

Ansible is a next-gen configuration management tool which has lot of advantages like agent-less, idempotent etc.,

Ansible provides pluggable architecture which can be helpful if you want to extend the functionalities in order to match your requirements and needs. This talk shades some light on this pluggable architecture in brief. After attending this session, you will be able to write your own plugin for Ansible and understand the workflow. This session requires intermediate knowledge about Ansible and its working. We will not focusing on basics of play or playbook or role. User is recommended to go through Ansible documentation or getting started sessions before attending this session.

Talk Outline:
- Introduction to Ansible
- What are plugins
- Types of Plugins
- Working with Plugins
- Plugin demo
- Writing your own plugin
- Q n’A

Introduction to Operators for App Developers

Kubernetes scales and manages stateless applications quite easily. Stateful applications can require more work. Databases, caching systems, and file stores are harder to dynamically manage with data intact, and sometimes come with their own notion of clustering. Operators are Kubernetes agents that know how to deploy, scale, manage, backup, and even upgrade complex, stateful applications.

This tutorial will provide an update on the Operator pattern from Red hat, adopted by many community projects like Rook, Prometheus, and others, and supported by this spring’s release of the Operator Framework and SDK. A follow-along demonstration will show the installation and use of an Operator on a OpenShift Kubernetes cluster.

Colin and Zdravomil, the linting heroes

Colin is a linter for container images and Dockerfiles. In this talk we would like to show you how you can check your images and Dockerfiles whether they pass basic rules. We certainly won’t stop there, we’ll also teach you how you can easily write your own checks.

You will also meet Zdravomil, our bot built on top of Colin. It can check your Dockerfiles in git repositories and send results through emails or pull request flags. See how easy it is to integrate Colin in your setup.
