Deployment is a good fit for managing a stateless application workload on your cluster, where any Pod in the Deployment is interchangeable and can be replaced if needed. Or you could use a container orchestrator — a tool designed to manage and run containers at scale. This article will teach you how to use Kubernetes (the most popular container orchestrator) to deploy your Node.js apps as Docker containers. To demonstrate, we will deploy an app called Knote on a Kubernetes cluster. Overview of deploying workloads. To deploy and manage your containerized applications and other workloads on your Google Kubernetes Engine (GKE) cluster, you use the Kubernetes system to create Kubernetes controller objects. These controller objects represent the applications, daemons, and batch jobs running on your clusters.We have explained all the MongoDB Kubernetes YAML files.
