kubernetes concepts

. Main concepts of Kubernetes 2.1 Pods In the Kubernetes system, the smallest granularity of scheduling is not simply a container, but a Pod. A Pod is the smallest deployment unit that can be created, destroyed, scheduled, and managed. One or more containers (Container) constitute a Pod. Generally, the containers in the Pod run the same application. Pods contain

Server saves the Node status information to ETCd. The Node Controller in Controller Manager regularly reads the status information of these nodes through the API Server and processes them accordingly. After listening to the information created by a Pod, Scheduler retrieves the list of all nodes that meet the Pod requirements and binds the Pod to the most compliant nodes in the node list: if schedpod detects that a Pod is deleted, the corresponding Pod instance on the current node is deleted. Fr

functions are as follows: 1 Use Docker for application wrapping (package), instantiating (instantiate), running (run). 2 to run and manage the containers across the machine in a cluster manner. 3 to solve the communication problem between Docker and cross machine containers. 4 Kubernetes's self-healing mechanism makes the container cluster always run in the user's desired state. The current kubernetes support GCE, Vshpere, CoreOS, OpenShift, Azure an

Guide:Kubernetes a ride on the dust to open, then the enterprise should start to kubernetes migration? Under what circumstances do you really accept it? Some of the technology frontier companies first-step practice is probably the most persuasive and reference value. This article is a good reference.1Kubernetes now rage, it is part of a massive cloud-native movement. All major cloud providers use it as a solution for deploying cloud-native application

Analysis of Kubernetes Application Deployment model (Principles) Abstract: this series of articles focus on actual deployment and give you a quick grasp of Kubernetes. This article describes the principles and concepts that need to be understood before deployment, including the Kubernetes component structure, functions

Recently in the Docker and her management tools, the selection of kuberetes, by her terminology and concepts to get dizzy ... Read an article is not bad, put it here to share.Address: http://www.linuxidc.com/Linux/2015-12/125757.htmThe citations are as follows:As an important member of the Docker ecosystem, Kubernetes is an open source version of Google's many years of large-scale container management techn

The Kubernetes network model is made up of four parts from inside to outside: The network where the pod interior container resides The network where the pod resides Network for communication between pod and service Network of communication between outside and service It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [

The architecture of Kubernetes is not covered here, although the architecture is biased, but we finally decide to use it and try to use only its Pod,replicationtroller and service capabilities. Here are some concepts to explain first: User: Products, development, testing, operations and other personnel under various product lines. Region: A preference for geographical

What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

First, the prefaceKubernetes is Google's Open source container cluster management system, based on Docker to build a container scheduling services, providing resource scheduling, equalization disaster tolerance, service registration, dynamic expansion capacity and other functional kits, the latest version of the current 0.6.2. This article describes how to build a Kubernetes platform based on Centos7.0, before the formal introduction, it is necessary

through some basic material on its concepts and so we can directly get down into its command S. The general perception about a management solution like kubernetes are that it would require quite a bit of setup for you T O Try it out locally. What This means's it would take some time to set it up but more than setting it up and you might probably get access to It only during staging phase or something as th

To understand and use kubernets, we need to understand the basic
