This is a creation in Article, where the information may have evolved or changed. Introduction to CRD and usage posture Customresourcedefinition (CRD) is the v1.7 + new mechanism to extend the Kubernetes API without changing the code to manage custom objects. It is actually an upgraded version of Thirdpartyresources (TPR), and TPR has been removed in v1.8. Some u

In the first two parts of this series we describe the overall process of API server and how the API objects are stored in ETCD. In this article we will explore how to extend the API resources.In the beginning, the only way to extend the API resources is to extend the relevant API source code and integrate it into the resources you need. Or, push a whole new type into the community code for the new core object API. However, this can lead to a constant increase in the core API resource types until

when a new node is added or fails, which is what operations people typically do when they manage. However, it is not very difficult to write an kubernetes operator.In short, the operator is kubernetes custom resource definition (CRD), which can write or use the existing. We are using Elastic search Operator and are happy to contribute to this project. I have mad

Required: Previously, the value of CN could be ignored for admission webhook to regenerate the server certificate. Now it must be set to the DNS name of the Webhook service: Custom Resource Definitions (CRDs) [Alpha] The Customresourcedefinition API now has the option to validate the JSON-schema-based custom object provided by CRD spec You can enable this feature through the Customresourcevalidation feature entry in Kube-apiser

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 [

Concept GroomingIn order to solve the above-mentioned problem, Kubernetes does not need to find a way, after all, is the network security level of the problem, every service will encounter problems, the industry has a mature solution to solve. Here we look at industry scenarios and related concepts.

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

ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's
