Containers offer an efficient way to package and operate your applications. In a production setting, it becomes crucial to oversee the containers running these applications and ensure uninterrupted functionality. For instance, when a container experiences an issue, it should be automatically replaced by another container. Wouldn't it be more convenient if this process were managed by a dedicated system?
Enter Kubernetes! Kubernetes offers a solution by furnishing a framework for robustly operating distributed systems. It handles tasks such as scaling and recovering your application, provides deployment strategies, and much more. For instance, Kubernetes can seamlessly orchestrate a canary deployment for your system.
With Kubernetes, you can effortlessly connect various storage options, including local storage and public cloud services, through automated procedures.
When you supply Kubernetes with a cluster of nodes for running containerized tasks and specify each container's CPU and memory requirements, Kubernetes optimally allocates containers to nodes, maximizing resource utilization.
In Kubernetes, containers that encounter issues are automatically restarted or replaced. Containers failing to respond to user-defined health checks are terminated, and they are not presented to clients until they are fully prepared to provide service.
Kubernetes offers a secure method for storing and handling sensitive data, including passwords, OAuth tokens, and SSH keys. You have the ability to deploy and modify secrets and application settings without the need to recreate your container images and without the risk of exposing these secrets within your stack configuration.
