Smooth Operator

Abstract

One of the challenges of orchestration tools such as Kubernetes is determining who works for who. It is easy to deploy a suite of applications into a cluster, but how do you manage the order and logic of provisioning, upgrading, or failure recovery? Is this left to humans manned with pagers? Operators was introduced a couple of years ago as the solution to this problem in the Kubernetes eco-system.

This talk will walk through the basics of Kubernetes APIs and Custom Resource Definitions (CRDs) which underpins the required basic understanding. We will identify the solution that operators provide with a look at the early stage sdks and frameworks. We will then focus on Kubernetes Universal Declarative Operator (KUDO) which is intended to be a declarative approach for create a new operator. Attends will leave with knowledge of how smooth building a new operator can be.

Go: Mistakes were Made (but not by me)

Abstract

Go can be a hyper-production language to develop in but like most languanges, has it's bad and "good parts". Just like what JavaScript: The Good parts did for JavaScript and what Effective Java did for Java, there are nuiances / gotchas to naviagate in Go. This sessions walks through a number of ways you can do it wrong with appropriate solutions.

This session will walking thru:

• Go best practices
• Go Common Mistakes

The facts are the Kuttling releases a cocktail of hormones in our brains including dopamine, serotonin and oxytocin.  It can lower your blood pressure and heart rate.  Nothing raises your blood pressure more than software written for Kubernetes that isn't tested.  

The KUbernetes Test TooL (kuttl) is a new tool for declarative testing of Kubernetes and Cloud Native software. kuttl empowers developers and end users to test operators, Helm charts, Kubernetes distributions, and Kubernetes itself. This session introduces attendees to testing kubernetes custom controllers using KUTTL with the expectation that all attendees already understand Kubernetes and operators.   The session will include:  

• Testing in different environments; mocked, KinD and full stack clusters.
• Test setup
• Controller injecting
• Asserting state goals
