kubernetes clinet-go Development (I.)
Kubernetes currently provides two ways to create the required pod,service,replicationcontroller, one is through Kubectl create-f, a restful interface via HTTP, because of the work item's reason, Need to be customized according to the actual business needs of the development of K8s API, I used the library is the official, code base address: Https://github.com/kubernetes/client-go, the following is my development i
thing. The main technical difference between diaspora and Facebook is the invisibility of end users: It's a "distributed" section.
NBSP;
diaspora infrastructure is not on a separate network address. There are hundreds of independent diaspora servers. The code is open source, so if you want, you can build your own server. Each server, called a pod, has its own database and its own collection of users, and ca
First, prefaceKubernetes is the Google Open Source container cluster management system, based on Docker to build a container scheduling service, providing resource scheduling, balanced disaster recovery, service registration, dynamic expansion capacity and other functional suites, currently the latest version is 0.6.2. This article describes how to build Kubernetes platform based on Centos7.0, before it is formally introduced, it is necessary to understand kubernetes several core concepts and th
projects, a tool reuse, a lot of time saving; (3) Can update the Open Source Library code on GitHub in time, just change the version number of the corresponding open source library in the Podfile file. I. Introduction of COCOA Pods Cocoa Pods is a tool responsible for managing third-party resources in iOS projects, and its project source code is managed on GitHub, thanks to the ongoing maintenance of the active GitHub developer community, which has been actively updated since the launch of th
. ImageService provides RPC to pull, view, and remove mirrors from the mirror repository. Runtimeserivce includes RPC for Pods and container lifecycle management, and calls to interact with containers (Exec/attach/port-forward). A single-block container runtime is capable of managing mirrors and containers (for example, Docker and Rkt), and both services are available through the same socket. This socket can be set in Kubelet by identifying –container-runtime-endpoint and –image-service-endpoint
open source libraries to the project, or to Git's submodule, and these open source libraries often need to rely on some framework of the system, I need to manually add these frameworks one by one to the project dependencies, For example, the ASI network Library needs to add the following framework:cfnetwork, SystemConfiguration, Mobilecoreservices, Coregraphics and zlib.
For regexkitlite This regular expression library, I also need to set the compilation parameters of-licucore

iOS programmers, it is essential to master the use of CocoaPods.How do I download and install CocoaPods?
Note: To use CocoaPods, You need to download and install CocoaPods. to download and install CocoaPods, you need the Ruby environment.
1. Ruby environment Installation

operation is complete, the corresponding files on the GitHub will be copied to the local directory structure:
The. gitignore file in the GitHub warehouse is a hidden file with a. Beginning, so you can see only two.All of our documents are added, deleted and changed in this catalogue.
Add the required files to the local git warehouse to create pods dependent libraries
Note: The files described below should be placed under the root directory of step two clone to the local git warehouse.1, su
Kubernetes Important Concept UnderstandingKubernetes is currently the most mainstream container orchestration tool, the next generation of distributed architecture of the king. 2018 Kubernetes The first version 1.10 has been released. Here's a look at some of the basic concepts of kubernetes.The kubernetes divides the machines in the cluster into master nodes and work nodes (node). The master node runs a set of processes Kube-apiserver, Kube-controller-manager, and Kube-schedule, as well as ETCD

In Docker there is the concept of data volume, when the container is deleted, the data will be deleted together, want to persist the use of data, you need to mount the directory on the host to Docker, in K8s, the data volume is persisted through the pod, if the pod is deleted, the data volume will be deleted together, K8s data volume is the expansion of the Docker data volume, k8s suitable for a variety of
Deploying Heketi and Glusterfs in Kubernetes[TOC]1. PrefaceIn Kubernetes, using the Glusterfs file system, the procedure is usually:Create brick--> Create volume--> Create pv--> create pvc-->pod mount PVCIf you are creating more than one PV, you need to manually repeat these interlocking steps, Heketi can resolve these duplication problems.Heketi is used to manage the life cycle of the glusterfs volume and provides a RESTful API interface for kubernet
the service resource, thereby modifying the Skydns record in the ETCD. The code can be found in the cluster/addons/dns/kube2sky/directory of the k8s source (v1.2).Exec-healthz is a secondary container provided by k8s and is used in side car mode. The principle is to periodically execute the specified Linux instructions to determine the health status of the key containers in the current pod. The function in Kube-dns is to check the health status of th

Based on the existing POD, the new trill pod domain is expanded horizontally. the L3 gateway of the TRILL domain is located at the aggregation layer and connected to the core layer through the routing protocol;
To solve the problem of dual-active access on the leaf layer, the leaf node supports N: 1 virtualization, such as the IRF of H3C;
The two aggregation nodes also perform N: 1 virtua
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-Kubernetes in the alpha development version of CoreOS Linux.
