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

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
Learning notes TF064: TensorFlow Kubernetes, tf064tensorflow AlphaGo: each experiment has 1000 nodes and each node has 4 GPUs and 4000 GPUs. Siri: 2 nodes and 8 GPUs for each experiment. AI research relies on massive data computing, instead of performance computing resources. The larger cluster running model shortens the weekly training time to the day-level hour level. Kubernetes, the most widely used cont
The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansion of kubernetes easier, we have been polishing the k8s plug-in API that supports containe
After the initial completion of the Kubernetes cluster architecture, by building some monitoring components, we have been able to achieve Graphical monitoring of status information and resource conditions for each node,pod Scaling and scaling of replicateset through scale View the run log for each pod by kubectl logs or dashboard However, the scale of the nodes in the distributed architecture is often very large, a typical produc

Service Account Usage ScenariosProcesses running in the pod need to invoke the Kubernetes API and other services of the non-Kubernetes

The Traefik principle can be consulted in the official documentation: https://docs.traefik.io/, This document can also be consulted about the service exposure of kubernetes and the rationale for using Traefik as a kubernetes ingress: https://mritd.me/2016/12/06/ Try-traefik-on-

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

In the previous blog post, we completed the Sonarqube deployment through Kubernetes's devlopment and service. Seems to be available, but there is still a big problem. We know that databases like MySQL need to keep data and not lose data. And the container is exactly the moment you exit, all data is lost. Once our Mysql-sonar container is restarted, any subsequent settings we make to Sonarqube will be lost. So we have to find a way to keep the MySQL data in the Mysql-sonar container.
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
