What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

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

is the starting learning environment? Can we know when a stock buyer is having problems?You need to run the following commands on all hosts before you deploy AOC. This command helps to avoid a known flannel and kube-proxy competition problem.Iptables -t Nat -I postrouting -o flannel. 1 -s host-private-IP -J Masquerade Replace with a private IP for each host host-private-ip . After completion, clone A

network stack network performance is the highest, bridge mode needs to be evaluated.Kubernetes uses a flat network model that requires each pod to have a globally unique ip,pod that directly communicates across hosts. At present, the more mature plan is to use flannel. Flannel has several modes of operation, namely UDP, VXLAN, HOST-GW, and aws-vpc. AWS-VPC has platform limitations we do not consider that U

Concept GroomingIn order to solve the above-mentioned problem, Kubernetes does not need to find a way, after all, is the network security level of the problem, every service will encounter problems, the industry has a mature solution to solve. Here we look at industry scenarios and related concepts. Symmetric encryption/Asymmetric encryptionThese two concepts belong to cryptography, which is not easy to understand for the students who have n

ProxyProxy not only solves the same host service port conflict problem, also provides service forwarding service port to provide services, the proxy backend using a random, round-robin load balancing algorithm.Third, kubernetes related componentsKubernetes mainly include: Kubectl, Kube-apiserver, K

This is a creation in Article, where the information may have evolved or changed. This period of time in the project group want to introduce Kubernetes, as a second-generation container scheduling engine, so recently in the system learning kubernetes. Organized a number of learning notes, experience, put on the blog, one to record their own learning through, and secondly see whether the need to help student
