Brief introductionKubernetes is an open source, containerized application for managing multiple hosts on a cloud platform, with the goal of making deploying containerized applications simple and efficient, Kuernetes provides a mechanism for application deployment, planning, updating, and maintenance.In Kubernetes, all containers are run in pods, and one pod can host one or more related containers. Each pod system created by the user automatically choo

Kubernetes Dashboard deployment of Docker 1. Environment Description: 1). Structure: Note: This experiment server environment all uses CentOS 7. The service installs all adopt Yum install. 192.168.3.7 Master192.168.3.16 node 2). Software packages used: Master:docker Kubernetes-master Etcd FlannelNodes:docker Kubernetes-node Flannel 3). Software version:

first, the core concept 1, Node node as a working node in a cluster, running a real application, the smallest unit of Kubernetes managed on node is pod. Node runs kubernetes kubelet, Kube-proxy service processes that are responsible for pod creation, start-up, monitoring, restart, destruction, and load balancing of software patterns. Node contains information: node address: The IP address of the host, or

This is a creation in Article, where the information may have evolved or changed. "Editor's word" is the collective idea of the operation of the company, but also a deep understanding of technology people, this article is the author in the practice of immutable infrastructure concept of the process of understanding the container, this is the first article, This paper focuses on the differences between traditional operational tools such as chef and Docker, as well as the solutions.

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

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 for Kubernetes Service Account RoleThe service account is designed to facilitate the process within the pod to invoke the Kubernetes API or other external services. Service Account Usage ScenariosProcesses running in the pod need to invoke the Kubernetes API and other services of the non-Kubernetes
