Kubernetes Operator explained | What are Kubernetes Operators and how it works ► Prometheus Operator in practice:    • Setup Prometheus Monitoring on Kubern...   🚀 Learn what a Kubernetes Operator is, why this operator concept even emerged and why you should use Kubernetes Operators. To give you an overview, operators are used mainly for stateful applications. So I first compare how Kubernetes manages stateless and stateful applications. And then compare deploying and managing stateful applications without an operator compared to deploying it with a Kubernetes Operator. ► 1. StateLESS applications on Kubernetes 🚀 Kubernetes can manage the complete lifecycle of stateless applications in a fully automated way, because these applications don’t have business logic for deployment. So basically, once you deployed the application, you don’t have to sit there and control that your application is running properly. ► 2. StateFUL applications WITHOUT Operator 🤯 For stateful applications, like databases, the whole process isn’t as straightforward. They need more "hand-holding" during its whole lifecycle, because the replicas of stateful apps aren't identical. So, Kubernetes natively doesn’t have all the knowledge required 🤷🏻‍♂️ to automate the process of deploying every single stateful application. That’s why these kind of applications require manual intervention - people who "operate" these applications. ► 3. StateFUL applications WITH Operator 🦄 Operator solves this problem and basically replaces this "human" operator with a "software" operator. At its core it has the same control loop mechanism that Kubernetes has, that watches for changes in the application state. It also uses CRDs, which is basically a custom K8s component. So, it takes the basic Kubernetes resources and its controller concept as a foundation to build upon, and on top of that includes application-specific knowledge to automate the entire life cycle of the application it "operates". ▬▬▬▬▬▬ T I M E S T A M P S ⏰ ▬▬▬▬▬▬ 0:00 - Intro 0:45 - Stateless applications on Kubernetes 2:21 - Stateful applications WITHOUT Kubernetes Operator 4:52 - Stateful applications WITH Kubernetes Operator 7:47 - Summary 8:33 - Who creates these operators? ▬▬▬▬▬▬ Want to learn more? 🚀 ▬▬▬▬▬▬ Full Kubernetes and Docker tutorial ► https://bit.ly/2YGeRp9 DevOps Tools, like Terraform, Prometheus ► https://bit.ly/2W9UEq6 Complete K8s Application Setup ►    • Complete Application Deployment using...   Jenkins Pipeline Tutorials ► https://bit.ly/2Wunx08 #kubernetes #kubernetestutorial #devops #techworldwithnana ▬▬▬▬▬▬ Connect with me 👋 ▬▬▬▬▬▬ Join private Facebook group ► https://bit.ly/32UVSZP Don't forget to subscribe ► https://bit.ly/3mO4jxT DEV ► https://bit.ly/3h2fqiO INSTAGRAM ► https://bit.ly/2F3LXYJ TWITTER ► https://bit.ly/3i54PUB LINKEDIN ► https://bit.ly/3hWOLVT ▬▬▬▬▬▬ Maybe interesting for you 😎 ▬▬▬▬▬▬ High-Quality and Hands-On Courses 👉🏼 https://bit.ly/3nIouPW Kubernetes 101 - cheatsheet for your work (handy ebook bundle) ► https://bit.ly/3mPIaiU Legal Notice: Kubernetes and the Kubernetes logo are trademarks or registered trademarks of The Linux Foundation in the United States and/or other countries.
