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

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

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
