As we all know, kubernetes (k8s) is used for the management of Docker cluster, the recent period of time has been tossing the environment, here to write a blog, to help like me, small white, avoid detours.

Kubernetes is Google's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of

Summary Project Background (XX Bank customer): The private cloud on the k8s to run like MySQL in the state of the database services, performance and latency are relatively sensitive, not like the web bias application of stateless delay performance almost acceptable. But the network performance and delay is poor based on overlay mode, and the network architecture is more complex. And banks need to be simple and controllable for IP network management. Sr-iov is based on hardware implementation of

volume plugins.1.8, the storage interest group extends the kubernetes storage API, no longer simply provides the available volumes, but also adds volume expansion and snapshot capabilities. In addition to these alpha/prototype features, the storage interest group focuses on giving users better control over their storage, providing the ability to set temporary storage requests limits, to specify mount options, to expose more storage metrics, and to i

. According to the Kubernetes resource model, QoS at pod level is divided into three levels: Guarantee, burstable, BestEffort, and we also set the standard for resource oversold according to the priority of the three levels corresponding to our application. Our QoS standards for app settings: Kubernetes comes with a component that uses guarantee Impor

CoreOS integrates Kubernetes Core Component Kubelet [Editor's note] This article introduces the integration and support of Kubernetes's Core Component kubelet in CoreOS, a news and description published by the official CoreOS blog. Installing and using Kubelet in CoreOS demonstrates Kubelet's usage skills and how to better manage and monitor container resources in Kubernetes.This week, we integrated a core embedded component of kubelet-

With such a large amount of data, there may be thousands of machines behind it, unable to manually monitor the state of the machine. Therefore, this article introduces the use of the Kubernetes container management tool and, through a simple example, tells you how to build a Spark cluster. Preparation Phase 1. You need to have a running kubernetes cluster and use KUBECTL to configure access permissions for

Here are some core concepts.ClusterA cluster is a set of nodes that can be physical servers or virtual machines, with the Kubernetes platform installed on top of them. Demonstrate such a cluster. Note that the diagram is designed to emphasize the simplification of core concepts. Here you can see a typical kubernetes
