How Does One `kubectl Apply` Command Deploy An App? Have you ever wondered how containerized applications are deployed and managed in cloud environments? In this video, we'll explain how the kubectl apply command works and why it's a key tool for deploying apps on Kubernetes. We'll start by describing how you create a YAML configuration file that outlines your app’s components, such as containers, replicas, and network settings. Then, we'll show how running the command sends this blueprint to the Kubernetes API server, which compares it with the current state of your cluster. We'll discuss how Kubernetes creates new resources or updates existing ones to match your desired setup, ensuring your app runs smoothly. You'll learn how changes like increasing the number of Pods or updating container images trigger automatic updates, including rolling updates that avoid downtime. Since kubectl apply uses a declarative approach, it only makes necessary adjustments, making your deployment process safe and repeatable. Whether you're deploying on cloud platforms like AWS, Azure, or Google Cloud, this process remains consistent. We'll also highlight how kubectl apply fits into DevOps workflows, enabling automated, reliable updates through CI/CD pipelines. Managing permissions with role-based access control adds an extra layer of security to your deployments. Join us for this detailed overview of how kubectl apply simplifies container orchestration, making app deployment faster, safer, and more consistent across any cloud infrastructure. ⬇️ Subscribe to our channel for more valuable insights. 🔗Subscribe: https://www.youtube.com/@CloudStackStudio/?sub_confirmation=1 #Kubernetes #CloudDeployment #DevOps #ContainerOrchestration #K8s #CloudInfrastructure #Automation #CI About Us: Welcome to Cloud Stack Studio, your go-to channel for all things cloud infrastructure.
