k8s dashboard

The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansion of kubernetes easier, we have been polishing the k8s plug-in API that supports container runtime: the Container Runtime interface (C

Objective In the K8S resource audit and billing this piece, the container and the virtual machine have very big difference. The container is not easy to implement relative to the virtual machine.Resource metrics can be collected using Heapster or Prometheus.

Kubernetes (commonly referred to as k8s) is a container orchestration tool for managing applications running in containers.Kubernetes not only has everything you need to support complex container applications, it is also the most convenient development and operational framework on the market.Kubernetes works by grouping containers to split an application into multiple logical units for ease of management and discovery. It is particularly useful for mi
