Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

Today brings you a tutorial on creating a kubernetes cluster quickly with Docker. This tutorial is based on my previous article "10-minute deployment of kubernetes cluster," updated, condensed. This tutorial has been verified by me many times, and it has some guiding sign
what is kubernetes.
Kubernetes is a new, container-based distributed architecture leading solution. is an open source version of Google's internal cluster management system, Borg. It was not known until April 2015, when the papers were published. Kubernetes is an open platform for development. is not limited to any one language and does not qualify any programm
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

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
By default, Kubernetes has a certificate validity period of 1 years when initializing a cluster. Manually generating certificates can avoid this problem.

Project Background (XX Bank customer): The private cloud on the k8s to run like MySQL in the state of the database services, performance and latency are relatively sensitive, not like the web bias application of stateless delay performance almost acceptable. But the network performance and delay is poor based on overlay mode, and the network architecture is more complex. And banks need to be simple and controllable for IP network management. Sr-iov is based on hardware implementation of

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
Use Rancher's RKE to quickly deploy a Kubernetes Cluster
Brief description:
This article involves three Ubuntu machines, one RKE deployment machine (192.168.3.161), and two Kubernetes cluster machines (3.162 and 3.163 ).
First on a Windows machine, download the rke_linux-amd64 from github, rename it rke, edit the cluster. the yml cluster deployment file uses the pscp Command provided by putty to upload the

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
