Understanding of the role of 1.configmapWhat role does the Configmap play?For example, enable a MySQL container. In general, the MySQL container is important for two parts, one for storing data and the other for configuration file MY.CNF.As previously tested, the storage data can be decoupled with the PV PVC implementation and the separation of the containers.The configuration file can also be decoupled fro

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 configure the network environment of the

Guide:Kubernetes a ride on the dust to open, then the enterprise should start to kubernetes migration? Under what circumstances do you really accept it? 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

The Kubernetes network model is made up of four parts from inside to outside: The network where the pod interior container resides The network where the pod resides Network for communication between pod and service Network of communication between outside and service It is recommended that you understand the network model of Docker before reading this article.

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 functio

Kubernetes is a docker-based, open-source container cluster management system initiated and maintained by the Google team that not only supports common cloud platforms, but also supports internal data centers.Built on top of Docker, Kubernetes can build a container scheduling service that allows users to manage cloud

Kubernetes, as an important member of the Docker ecosystem, is an open source version of Google's many years of large-scale container management technology, as Urs Hölzle said, whether it is a public cloud or a private cloud or even a hybrid cloud, kubernetes will be used as an application for any The container managem
