JTC18 Kubernetes Advanced Labs
Lab0 - Lab information
Kubernetes is a container orchestrator to provision, manage, and scale applications. In other words, Kubernetes allows you to manage the lifecycle of containerized applications within a cluster of nodes (which are a collection of worker machines, for example, VMs, physical machines etc.).
The key paradigm of kubernetes is it’s Declarative model. The user provides the “desired state” and Kubernetes will do it’s best make it happen. If you need 5 instances, you do not start 5 separate instances on your own but rather tell Kubernetes that you need 5 instances and Kubernetes will reconcile the state automatically. Simply at this point you need to know that you declare the state you want and Kubernetes makes that happen. If something goes wrong with one of your instances and it crashes, Kubernetes still knows the desired state and creates a new instances on an available node.
In this Lab you will learn the basic concepts for working with Kubernetes.
