The node includes a mirror called MONGO, derived from the [Docker Hub], which exposes 27107 ports. The

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 networ

accessed? The service provides transparent load balancing between the 2 background pods, distributing the request to any one of them (as shown in the following animation). Completed by the agent running on each node (kube-proxy). More technical details are available here.There is a special type of kubernetes service called ' LoadBalancer ', which is used as an

The core issue in Kubernetes architecture is how data is persistance, although it provides persistent volumn, but it is difficult to run and manage products like databases in a kubernetes cluster environment. Kubernetes provides endpoints this mode to map external services into internal services, which solves the probl

. Services can expose external services through a nodeport,loadbalancer approach. Note that type = LoadBalancer requires a cloud service platform to provide the basis for the service, the k8s cluster by default is not this thing. If you define the service type = LoadBalancer on the Ali Cloud, you will find that the loa

Service is the core concept of k8s. By creating a service, you can provide a unified portal address for a set of container apps that have the same functionality, and distribute the request load to the various containers on the backend to applyService Definition DetailedThe full contents of the service definition file in the Ymal format are as followsapiversion:v1

Configure the dashboard service for a Kubernetes Cluster This article describes how to create and use kube-ui (also called dashboard) based on the previous article. This is essentially an api interface for connecting webui to the master. It obtains information about the k8s cluster through the api and then displays it on the web, which is more friendly to users, it is not very useful. 1. Download image file

cluster of containers. Here's how to get this app deployed and running in the k8s cluster.Actually, it's simple. (This is, of course, an entry-level demonstration, with a lot of detail to adjust for each command)1. Specify the image to pull with the Kubectl Run command, and run it by setting certain parameters. The term k8s This process is called creating a deployment (Deployment)Kubectl run Mvcapp--image chenxizhang/mvcapp--env= "aspnetcore_urls=http://+:80"2. Expose this deployment in some wa

. And since Kube-dns as another service of kubernetes, there is no tight binding between Kubelet and Kube-dns. You only need to pass the IP address and domain name of the DNS service to Kubelet, and Kubernetes does not care who is actually processing the

Service discovery mechanism Kubernetes provides two ways to discover the service:1. Environment Variables When the pod is running, Kubernetes writes the information for the service that existed before This method requires that the pod must be started after the
