Kubernetes is designed with self-healing capabilities that help maintain the health and availability of workloads. It automatically replaces failed containers, reschedules workloads when nodes become unavailable, and ensures that the desired state of the system is maintained. Self-Healing capabilities Container-level restarts: If a container inside a Pod fails, Kubernetes restarts it based on the restartPolicy. Replica replacement: If a Pod in a Deployment or StatefulSet fails, Kubernetes creates a replacement Pod to maintain the specified number of replicas.

Production-Grade Container Orchestration

Windows applications constitute a large portion of the services and applications that run in many organizations. Windows containers provide a way to encapsulate processes and package dependencies, making it easier to use DevOps practices and follow cloud native patterns for Windows applications. Organizations with investments in Windows-based applications and Linux-based applications don't have to look for separate orchestrators to manage their workloads, leading to increased operational efficiencies across their deployments, regardless of operating system.

FEATURE STATE: Kubernetes v1.19 [stable] The scheduling framework is a pluggable architecture for the Kubernetes scheduler. It consists of a set of "plugin" APIs that are compiled directly into the scheduler. These APIs allow most scheduling features to be implemented as plugins, while keeping the scheduling "core" lightweight and maintainable. Refer to the design proposal of the scheduling framework for more technical information on the design of the framework.

Networking is a central part of Kubernetes, but it can be challenging to understand exactly how it is expected to work. There are 4 distinct networking problems to address: Highly-coupled container-to-container communications: this is solved by Pods and localhost communications. Pod-to-Pod communications: this is the primary focus of this document. Pod-to-Service communications: this is covered by Services. External-to-Service communications: this is also covered by Services. Kubernetes is all about sharing machines among applications.

These guidelines cover the main Kubernetes blog and the Kubernetes contributor blog. All blog content must also adhere to the overall policy in the content guide. Before you begin Make sure you are familiar with the introduction sections of contributing to Kubernetes blogs, not just to learn about the two official blogs and the differences between them, but also to get an overview of the process. Original content The Kubernetes project accepts original content only, in English.

System component metrics can give a better look into what is happening inside them. Metrics are particularly useful for building dashboards and alerts. Kubernetes components emit metrics in Prometheus format. This format is structured plain text, designed so that people and machines can both read it. Metrics in Kubernetes In most cases metrics are available on /metrics endpoint of the HTTP server. For components that don't expose endpoint by default, it can be enabled using --bind-address flag.
