Operator Framework ⚡️
On this week’s Kubelist Podcast we sit down with Evan Cordell from RedHat and chat about the past, present and future of the incubating Operator Framework project. For the newsletter, we’re going to take a deep dive into operators and how they fit in the Kubernetes ecosystem; and look at the challenges and tools associated with them. Make sure to checkout Operatorhub for a list of what's already out there!
Issue #126
We’re going to use the Wayback Machine to check out when Brandon Phillps and the CoreOS(RIP) team introduced us to operators! It’s still an awesome post that does a great job of outlining what operators can do, what they are for, and how they came to be. ✨
This tutorial guides you through setting up your own Operator and leveraging Operator SDK. Some GO knowledge is required, but it is quite educational and shows you fundamentally how to leverage operators for your day-1 and day-2 needs through the lens of Memcached. 🔍
Once you build your own Operator, you have to maintain and upgrade it–and that's where OLM comes in. We take you straight to the docs to get you going. By no means is OLM just about upgrading; it also helps you manage dependencies, discoverability, and stability for all of your operators. Bonus: Check out the community guiding this project! 🪄
There is more than one way to build an Operator, and here’s a nice write up that goes through a large chunk of your options. They dive into language choices and framework, along with handy code snippets and real-world implementations. 🛠
When one discusses operators, one must discuss CRDs! Evan brings up Kubebuilder, and it's a great project to take a look at to see if it’s helpful to you! You can jump straight to the getting started, or read up on the thinking behind the project!
Really cool. The sandbox is growing quickly and this was amazing to watch. We’ll share the recording link when it’s available, because the whirlwind tour of the sandbox was amazing.
