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 c

containers are pod containers and app containers created by the author in the Kubernetes-dashboard of the [kubernetes]kubernetes Cluster and Docker Private library build (CentOS 7) article. The pod container is running in the bridge network driven by flannel:# Docker Network Inspect bridge[ { "Name": "Bridge", "Id":

Some of the technology frontier companies first-step practice is probably the most persuasive and reference value. This article is a good reference.1Kubernetes now rage, it is part of a massive cloud-native movement. All major cloud providers use it as a solution for deploying cloud-native application

Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three components:kube-apiserverkube-schedulerkube-controller-managerThis three components are closely li

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

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.
