Analysis of Kubernetes Application Deployment model (Principles)
Abstract: this series of articles focus on actual deployment and give you a quick grasp of Kubernetes. This article describes the principles and concepts that need to be understood before deployment, including
Detailed guide for manual installation and deployment of Kubernetes on Ubuntu, ubuntukubernetes
Background
Two Ubuntu16.04 servers: 192.168.56.160 and 192.168.56.161.
Kubernetes version: 1.5.5
Docker version: 1.12.6
Etcd version: 2.2.1
Flannel version: 0.5.6
Among them, 160 servers are both master nodes of Kubernetes a

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,
Hi,everybody, I came back, before the installation to flannel, the article has not been updated, even a lot of small partners to add QQ asked whether to continue to update,Here is the reason, I was in the deployment of 1.91node when there are a variety of problems, resulting in node startup Oh, master always do not see, the problem is probably1, Virtual machine time synchronization inconsistency problem, causing ETCD to create a resource is unsuccessf

Controller manager, as the Management control center within the cluster, is responsible for the resource management in the cluster, including node, Pod, namespace, and rated resources. For example, when an unexpected node outage occurs, Controller Manager will promptly discover and perform an automated fix.First, deploy k8s Controller ManagerMake sure Controller-manager-key.pem and Controller-manager.pem exist, and I've created the relevant private key here in the previous article. Perform the f
The role of Kubernetes Scheduler is to bind controller manager to a new pod according to a specific scheduling algorithm and scheduling policy to a suitable node in the cluster, and to write the binding information to the ETCD.I.

Given the popularity of Docker, Google launched Kubernetes management docker cluster, and many people are expected to try. Kubernetes is supported by a large number of companies, and the Kubernetes Cluster deployment Tool integrates the IaaS platform such as Gce,coreos,aws, which is also very convenient to deploy. Give

first introduce what k8s is: (Quote from k8s Chinese community)Kubernetes is a container cluster management system, it is an open source platform, can realize the automatic deployment of container cluster, auto-scaling capacity, maintenance and other functions. Kubernetes you can:

Kube-proxy uses the ETCD watch mechanism to monitor the dynamic changes of service and endpoint object data in the cluster and to maintain a service-to-endpoint mapping From the page to ensure that the IP changes in the backend pod do not affect the visitor. Kube-proxy also supports session affinity.Kublet:kublet is the agent of master on each node, and is the most important module on node, and it is responsible for maintaining and managing all the containers on that node, but it w

Every time we buy a machine, usually hundreds of nodes, so the deployment of the entire platform is very headache, especially CoreOS and kubernetes, must use ladder to install and update, peopl
