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

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL data in the Mysql-sonar container.

What is PodPods are the smallest deployable units that can be used to create and manage kubernetes calculations. A pod represents a process that runs in a cluster.Pods are like pea pods, which consist of one or more containers (such as Docker containers) that share container storage, network, and container run configuration items. The containers in the pod are always dispatched at the same time and have a common operating environment. You can think of

Introduction and practice of pod in kubernetes The concept of podDetailed pod explanation can refer to k8s official website, the concept of pod mainly has the following points:(1) Pod is the smallest and simplest unit that you can create and deploy in Kubernetes. A pod represents a process that runs in a cluster;(2) How to use pod in kubrenetes cluster;(3) How to manage multiple containers in pod Unde

[TOC]Introduction to Kubernetes DispatchingIn addition to having the Kubernetes cluster scheduler automatically select a node for the pod resource (the default schedule is that the resources are sufficient and the load is as average as possible), there are situations where we want to have more control over how the pod should be dispatched. For example, some of the machines in the cluster are better configur

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

Official Document: HTTPS://WWW.KUBERNETES.ORG.CN/DOC-11The Kubernetes cluster contains the node agent Kubelet and master components (APIs, scheduler, etc), all based on a distributed storage system. The following diagram is an architectural diagram of the kubernetes.Kubernetes nodeIn this system architecture diagram, we divide the service into services running on the work nodes and the services that make up the cluster-level dashboard.The

Service discovery mechanism Kubernetes provides two ways to discover the service:1. Environment Variables When the pod is running, Kubernetes writes the information for the service that existed before This method requires that the pod must be started after the service. The pod that was started before the service will not have an environment variable for that service. There is no such limit in the way

Basic knowledgeFirst: Docker is an open-source container, in fact this technology is not new. In the early days of Linux, there was a lightweight virtualization system like LXC. Docker is actually just a language to implement. Kubernetes means the helmsman of sailing, it's a powerful orchestration + Monitor + disaster preparedness + load management system for DockerSecond: Kubernetes is a summary and best p
