Use Kubernetes to manage containers on centos 71. Preface The previous section describes the Kubernetes system architecture, which gives you a preliminary understanding of Kubernetes. However, you may not know how to use Kubernetes. This article describes how to deploy and configure the network environment of the Kubernetes cluster locally and demonstrate cross-machine service communication through instances. The main content of this article is as follows: Deployment Environment Logic archite

Kubernetes Kubeadm installation requires the following four packages Kubelet Kubernetes-cni Kubeadm kubectl These four packages can be downloaded via the Https://github.com/kubernetes/kubernetes warehouse to perform make fetch installation packages, and the release version is required if the RPM package is required.

Use traefik to publish a service in a kuberneters Cluster The previous article has introduced the implementation principle and configuration of k8s ingress. This article will introduce the alternative solution traefik. Before starting the configuration, let's review the implementation scheme of the k8s Service released by ingress. The ingress solution requires the following components: 1. Reverse Proxy Server Load balancer2. ingress control3. ingressThe ingress control communicates with the apis

Official Document: HTTPS://WWW.KUBERNETES.ORG.CN/DOC-11The Kubernetes cluster contains the node agent Kubelet and master components (APIs, scheduler, etc), all based on a distributed storage system. The following diagram is an architectural diagram of the kubernetes.Kubernetes nodeIn this system architecture diagram, we divide the service into services running on the work nodes and the services that make up the cluster-level dashboard.The Kubernetes node has the services required to run the appl

Previous blog post have introduced the use of KUBEADM Automation to install kubernetes, but since each component is run as a container, there is not much involved in the specifics of the configuration, in order to better understand the role of each component in Kubernetes, This post will install the Kubernetes cluster using a binary approach, with detailed instructions for the configuration of each component. In version 1.10, the connection to non-secure ports (default 8080) has been ph
