how to install kubernetes

Pokemon per second processing of Go cloud data storage (expected vs Actual) This can happen, and you should be prepared for it as well. This is also the article in this series to mention. In this series of tutorials we'll show you what you need to track, why you're tracking them, and what you need to do to deal with possible root causes. We'll show you each indicator, how to track it, and what you can do to take action. We will use different tools to collect and analyze this data.

For those who are interested in this offline event, please click here to sign up for a free ticket.In March this year, Docker had just finished its 5 birthday, and for five years, Docker had gradually matured in technology and practice, and embraced kubernetes at the end of last year.May 19, NetEase Cloud will co-host Docker Meetup, invite industry Docker deep practice enterprise, share in container, micro-service and

Previous Chapters Kubernetes All operations we are using command line tools kubectl completed. To provide a richer user experience, Kubernetes also developed a WEB-based Dashboard that enables users to deploy containerized applications with Kubernetes Dashboard, monitor the status of applications, perform troubleshooting tasks, and manage

Tags: composition instance provider application Application class version style implementationThe lifespan of kubernetes pods is limited and they are not resurrected, so although each pod has its own IP address, these IP addresses are unreliable and disappear as the pod dies. This poses a problem, if some of the pod's collections (called backends) are other pods of the cluster (called frontends), how do these frontends find and always know which backe

the IP needs to be within the specified IP address range of the Kube-apiserver boot parameter –service-cluster-ip-range. and Skydns If it is a localized installation, it is not possible to bind the IP of the DNS server to the IP of a virtual network (that is, the value of the parameter-addr). I would prefer to install it using mirroring mode. InstallationThe contents of the file Kubernetes-dns.yaml as foll

Wrote an article about Jenkins integrated Docker very early, using the cloudbees Docker Build and Publish plugin plugin. This article is done directly with the shell script, mainly this time there is a need to detect whether the harbor warehouse is already existing to build the image, if it exists to abandon the build, if not exist then build the image and upload to the Harbor warehouse, I am here by Request Harbor API to detect.The whole process is roughly divided into four steps, drawing a sim

This article describes the deployment of a PHP application system in the kubernetes environment. The front-end Web uses nginx, middleware PHP to run in fastcgi way, the background database is supported by MySQL master and slave.Calls between service components take the form of DNS resolution service names, and data and configuration files are persisted using PV and PVC (based on NFS).First, create a PHP image file via Dockerfile# cat dockerfile FROM d

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

Author: Peng Jingtian The node nodes of Kubernetes are composed of Kubelet, Kube-proxy, flannel, dockerd four components, this paper mainly analyzes the functions and principles of kube-proxy components. Pod is the smallest unit of resource allocation in kubernetes and the smallest entity to perform tasks. Each pod has a separate IP on the flannel overlay network. Pod Communication in node nodes is impleme

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

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

ReviewSimply put: Each component version that Kubernetes relies on can be found in the corresponding ChanglogFor example, version 1.10 depends on the following conditions:Https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md#external-dependenciesThe following simple example summarizes:k8s v1.10 dependent version Select 1.10.0 Dependent package:Ht

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.

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

This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to understand what the next Prometheus is. Prometheu

In a cluster with TLS enabled, each time the cluster interacts with identity authentication, using Kubeconfig (i.e., certificates) and token two authentication methods is the simplest and most common authentication method.Take Kubectl as an example to introduce the configuration of Kubeconfig. Kubectl is just a go-written executable program that can be used by any node in the cluster as long as the appropriate Kubeconfig is configured for Kubectl. Kubectl Default is to find files with file names
