beginners.Then there are classmates asked, there are a lot of binary installation of the tutorial, why do I also repeat the wheel? Indeed, K8s's binary installation method does have a lot of tutorials, I also have to look at the introduction, there are two main tutorials, one is a fool, also called a button, run a command, execute a script, all done (of course, will encounter some problems, you need to find a way to solve the ^_^). There is also a complex, step-by-step everything is written dow

Kubernetes-initial experience of Google distributed container Technology Kubernetes is an open-source container Cluster Management System of Google. The four features of the distributed service framework written a few days ago mentioned that a good distributed service framework needs to be implemented. Service configuration management. Including service discovery, Server Load balancer, and service dependenc

As we all know, Amazon has EC2 container service, which is the solution that Amazon uses to run Docker containers. But I don't think EC2 container service is very good, so now I'm going to test rancher and Kubernetes on AWS.Kubernetes is an open-source system for automating deployment, scaling, and managing containerized applications. Rancher is a complete container management and runtime platform that can be used within the enterprise, providing ente

I. Introduction ofKubernetesKubernetes is 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, using Kubernetes can easily manage the cross-machine operation of containerized applications. and Kubernetes supports

This is a creation in Article, where the information may have evolved or changed. This period of time in the project group want to introduce Kubernetes, as a second-generation container scheduling engine, so recently in the system learning kubernetes. Organized a number of learning notes, experience, put on the blog, one to record their own learning through, and secondly see whether the need to help student

Google Kubernetes Engine upgrade: regional cluster, new control panel, and security recommendations Google has updated its Kubernetes Engine (GKE) service several times. You can now use GKE on a large scale. In addition to the kubectl command for cluster control and management, it also supports cluster management through the Cloud Console of a Web-side control panel. In addition, GKE can use Google best pra

The development track of modern cloud computing from the perspective of container and Kubernetes Technology [Editor's note] This article is selected from the Google Cloud Platform Blog. It is the beginning of a series of blogs that mainly introduce container technology. This article briefly introduces container technology and kubernetes, describes the advantages of container technology and Google's understa

Because scenarios where private clouds are deployed in the enterprise are more prevalent, it is necessary to build a network environment that meets kubernetes requirements before running kubernetes + Docker clusters in a private cloud. In today's open source world, there are many open source components that can help us get through the network between Docker containers and containers, and achieve the

This is a creation in Article, where the information may have evolved or changed. "Editor's word" Jenkins, as the most popular continuous integration tool, in combination with the use of container technology, kubernetes cluster based on how to play a new capacity, in the application of micro-service based on the provision of better CI way, it is worth each of our developers to continue to explore. This share mainly introduces how we use Jenkins Pipeli

Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them. This article describes how to use Docker and Kubernetes to build a set

Kubernetes Cluster Deployment DNS ServiceIn Kubernetes each service will be assigned a virtual IP, each service under normal circumstances will not change for a long time, this is relative to the pod of the indefinite IP, the use of the cluster app is relatively stable.But the service's information injected into the pod is currently using an environment variable, and relies heavily on pod (RC) and service c

This is a creation in Article, where the information may have evolved or changed. What is the difference between Apache's Mesos and Google's kubernetes? This article comes from a question on the StackOverflow, mainly discusses the difference between Mesos and kubernetes, I believe many of us also have the question of agreeing. Kubernetes's developer Craig answered the question, while Masi also made an overv

Kubernetes introduced Kubeadm from 1.3 to try to simplify its complex installation. But Kubeadm is still not stable, and I personally think Kubeadm instead of trouble, rather than directly with the script or other automated tools to install the neat. There are also alternatives to HA for KUBEADM configuration master, such as using highly available cluster software such as keepalived or Corosync. So in this document, I will still use the traditional wa

Come on , the first question:Rancher can quickly deploy kubernetes, but its use of the Gcr.io on the mirror cannot download what to do? With rancher you can quickly deploy kubernetes, but what images do we need to download? Rancher Support Private Image warehouse, how to set it? Problem Solving Ideas:Although the domestic network does not have direct access to the Gcr.io server, it has access to the hub.doc

First, kubernetes architectureKubernetes is the Google Open Source container cluster Management system, which provides application deployment, maintenance, extension mechanisms and other functions, using kubernetes can easily manage the cross-machine operation of containerized applications, the main functions are as follows:1) Use Docker for application wrapping (package), instantiation (instantiate), and r
