Writing Kubernetes Operator using Operator SDK
Kubernetes (K8s) operators are a great way to deploy and manage your Kubernetes application.
The operator is basically a construct. In a cloud-native environment, anything that can package, deploy, and manage your application in the cloud becomes an Operator.
Being a developer, it is upto us whether we want to be the operator or let software handle it.
In Kubernetes, we can leverage operators to extend, add, and manage Kubernetes’ specific functionalities and automate administrative tasks as if working with a native K8s component.
There are many useful operators open-sourced by various communities that achieve specific tasks, for example, CoreOS has released Prometheus operator for your cluster monitoring, Etcd operator for managing etcd database cluster in K8s and many more.
For me, it took time to understand how to write an operator from scratch, and after digging through the user guide and going through existing operators, I finally was able to write a simple operator that solves the purpose of log management in our cluster. So here I’ve put down the basic concept of writing a simple operator using CoreOS’s Operator-SDK.

50+ Useful Kubernetes Tools for 2020 - Part 2
Introduction
Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.
According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.
And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Download Android SDK Manager and SDK Tools
In this tutorial, we’ll read about the Android SDK Manager. We will see what is SDK manager in Android and why and how it is important for Android. So, SDK stands for Software Development Kit, which is a collection of software tools required. SDK basically helps Android to download tools and recent versions of Android. Every time a new Android version is released, along with it is released an SDK corresponding to it. This SDK must be installed by the developers for the devices.
What is SDK Manager?
A Software development kit is a set of tools required for the development of applications for Android. It also ensures that the progress of App development goes as flat as pancakes. We need SDK irrespective of the language we are using. Android SDK comes wrapped up with the Android Studio these days. An Android SDK separates the tools, platforms and other components into packages. These can be downloaded from the SDK Manager.

Understanding Kubernetes Operators
Automation is one of the fundamental components that makes Kubernetes so robust as a containerization engine. Even complex cloud infrastructure creation can be automated in order to simplify the process of managing cloud deployments. Despite the capability of leveraging so many resources and components to support an application, your cloud environment can still be fairly manageable.
Despite the many tools available on Kubernetes, the effort to make cloud infrastructure management more scalable and automated is ongoing. Kubernetes operator is one of the tools designed to push automation past its limits. You can do so much more without having to rely on manual inputs every time.
Getting to Know Kubernetes Operators
A Kubernetes operator, by definition, is an orchestration framework. It is a tool that lets you orchestrate and maintain cloud infrastructures with little to no human input. Kubernetes define operators as software extensions designed to utilize custom resources to manage applications and their components.
Kubernetes operators are not complex at all. Operators use controllers and the Kubernetes API to handle packaging, deployment, management, and maintenance of applications and the custom resources that they need. The whole process is fully automated, plus you can still rely on _kubectl _tooling for commands and operations.
In other words, an operator is basically a custom Kubernetes controller that integrates custom resources for management purposes. You can define parameters and configurations inside the custom resources directly, and then let the operators translate those parameters and run autonomously. Kubernetes operators’ continuous nature is their defining factor.

What Is a Kubernetes Operator and Why it Matters for SRE
Kubernetes is an open-source project that “containerizes” workloads and services and manages deployment and configurations. Released by Google in 2015, Kubernetes is now maintained by the Cloud Native Computing Foundation. Since its release, it has become a worldwide phenomenon. The majority of cloud-native companies use it, SaaS vendors offer commercial prebuilt versions, and there’s even an annual convention!
What has made Kubernetes become such a fundamental service? A major factor is its automation capabilities. Kubernetes can automatically make changes to the configuration of deployed containers or even deploy new containers based on metrics it tracks or requests made by engineers. Having Kubernetes handle these processes saves time, eliminates toil, and increases consistency.
If these benefits sound familiar, it might be because they overlap with the philosophies of SRE. But how do you incorporate the automation of Kubernetes into your SRE practices? In this blog post, we’ll explain the Kubernetes Operator—the Kubernetes function at the heart of customized automation—and discuss how it can evolve your SRE solution.
What the Kubernetes Operator Can Do
In Kubernetes Operators: Automating the Container Orchestration Platform, authors Jason Dobies and Joshua Wood describe an Operator as “an automated Site Reliability Engineer for its application.” Given an SRE’s multifaceted experience and diverse workload, this is a bold statement. So what exactly can the Operator do?
