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 under

How to obtain a Kubernetes image in China I. background As we all know, due to domestic network reasons, when building a Kubernetes environment, we often encounter situations where necessary images cannot be found. After all, it is not a good way to pick up junk in DockerHub. This article will teach you how to build your own image repository in DockerHub. Requirement: You have a GitHub account and a DockerH

With the popularity of micro-service architectures and the trend of cloud-native, containerized microservices have become the best product of continuous delivery and have become the kubernetes best ecosystem for operation and maintenance containers. Practice out of knowledge, since kubernetes the study, wrote a series of articles, in order to be able to learn from each other, to find knowledge of the loopho

The current skaffold version is v0.4 and has not yet been released, and is not recommended for use in production environments;Skaffold is used for developer rapid deployment programs to Kubernetes,Skaffold provides dev, run two modes , and Skaffold requires a skaffold configuration file that defines Skaffold workflow ；The Skaffold workflow defines three main stages : Build, Push, Deploy;First, BuildDuring the build phase, Skaffold uses the dockerfile

As early as half a year ago, the company began to implement the container deployment scheme Appos, although the publishing interface is too geek, very obscure, but carefully studied really feel very powerful, after the implementation of the container, computing resources (CPU, memory) utilization can be greatly improved, reduce the number of servers, thereby saving technical costs. Coincidentally, a number of friends in the start-up companies are also recently trying to do micro-services, contai

the style and logic of the above code is no longer familiar: Create a The Schedulerserver object, which passes command-line arguments, and enters the schedulerserver Run method, does not die. --"kubernetes authoritative guide" source code guidance Kubernetes Scheduler Server is implemented by the Kube-scheduler process, which runs on the Kubernetes management nod

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

First, IntroductionHeapster is a cluster-wide monitoring and event data aggregator. It natively supports kubernetes and can be run on all kubernetes settings. Heapster is run as a cluster in a group, similar to how any other kubernetes application runs. InfluxDB is an open source database written in go that is designed to handle time-series data with hi

in the previous section we discussed the services running on the Kubernetes architecture Master,This section discusses node nodes. Node is where the Pod runs, Kubernetes supports Docker, Rkt, and other container runtime. The Kubernetes components running on node have Kubelet, Kube-proxy, and Pod networks (such as flannel).KubeletKubelet is the agent of node, and

GlusterFSGlusterfs is an open-source, scale-out file system. These examples provide information about how to allow containers to use glusterfs volumes.The example assumes that you have set up the Glusterfs server cluster and is ready to use the running Glusterfs volume in the container.PrerequisiteThe Kubernetes cluster has been built.Installation of the Glusterfs clusterEnvironment IntroductionOS System: Centos 7.xGlusterfs of two nodes: 192.168.22.2
