what container orchestration is. explore how developers can use container orchestration to create and manage complex container environment development lifecycles. Kubernetes is currently the most popular container orchestration platform. You’ll examine key Kubernetes architectural components, including control plane components and controllers. Explore Kubernetes objects, and learn how specific Kubernetes objects such as Pods, ReplicaSets, and Deployments work. Then, learn how developers use the Kubernetes command line interface (CLI), or “kubectl” to manipulate objects, manage workloads in a Kubernetes cluster, and apply basic kubectl commands. Dfferentiate the benefits and drawbacks of using imperative and declarative commands. use the kubectl CLI commands to create resources on an actual Kubernetes cluster. Kubernetes CLI to create a Kubernetes pod, create a Kubernetes deployment, create a ReplicaSet and see Kubernetes load balancing in action.

explore ReplicaSets, autoscaling, rolling updates, ConfigMaps, Secrets, and service bindings, and learn how you can use these capabilities to manage Kubernetes applications. learn how ReplicaSets scale applications to meet increasing demand, and how autoscaling creates dynamic demand-based scaling. how to use rolling updates to publish application updates and roll back changes without interrupting the user experience. learn how to use ConfigMaps and Secrets to provide configuration variables and sensitive information to your deployments and to keep your code clean. scale and update applications deployed in Kubernetes.
