glusterfs kubernetes

ClusterCluster is a collection of compute, storage, and network resources, and Kubernetes uses these resources to run various container-based applicationsMasterMaster is the brain of cluster, whose primary responsibility is scheduling, that is, deciding where the application will run. Master runs the Linux operating system, which can be either a physical machine or a virtual machine. To achieve high availability, you can run multiple master.NodeNode's

On multiple nodes after glusterfs is successfully installed, you can manage each node through the gluster Management Console. After successful addition, the public key can be automatically installed, however, if manual installation is required, you can configure the public key on each node according to the following steps. 1. First modify the/etc/hosts file to include the names and IP addresses of all nodes in the cluster; For example, 192.168.1.1

78480241First, Background introduction 众所周知，由于国内网络原因，在搭建 Kubernetes 环境时，经常遇到必须的镜像找不到的情况。 到 DockerHub 捡垃圾毕竟不是个好办法，本文就教大家在 DockerHub 搭建自己的镜像仓库。 要求：有 GitHub 账号，有 DockerHub 账号，没有请注册。Ii. Basic Steps2.1 登陆 GitHub，创建代码仓库，比如：googlecontainer2.2 克隆代码（地址换成你的）#git Clone Https://github.com/SataQiu/googlecontainer.git2.3 Writing Dockerfile (take dashboard as an example)[Plain] View plain copy#cd Googlecontainer#mkdir Dashboard#cd Dashboard#vi

Containerized technology (containerization).You may have a lot of doubts: what exactly is a container and how does it work? What does Docker and kubernetes mean, and what is the use of Google Container engine and managed VMS? How are they related, and how can we build a powerful service through containers and make them available in a large-scale cluster of production environments? How can you get business value by using this technology? Well, we don't

ObjectiveThis article is a reading note, specific reference to Mr. Nu Bongfei's original "Kubernetes Guide", thank the original author, salute!I. Introduction of BorgBorg is a large-scale cluster management system within Google, which is responsible for the scheduling and management of many core services within Google.The goal of Borg is to enable users to focus on their core business without having to worry about resource management, and to maximize

Kubernetes using NFS as a shared storageKubernetes managed containers are encapsulated, and sometimes we need to put logs from the container running locally or shared storage to prevent the container from going down, and the logs can also analyze the problem. Kubernetes's shared storage scheme is currently more prevalent in three, namely: Nfs,glusterfs and Ceph.Previously wrote an article

I. Background INTRODUCTION As we all know, due to the domestic network reasons, in the construction of kubernetes environment, often encountered the need for the mirror can not find the situation. After all, it is not a good idea to pick up rubbish in Dockerhub, this article teaches everyone to build their own mirror warehouse in Dockerhub. Request: Have GitHub account number, have dockerhub account number, do not register. Second, the basic steps 2.1

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.

This is a creation in Article, where the information may have evolved or changed. Hello everyone, I am Xu Chao, engaged in Kubernetes development has been more than two years. Today, I talk about Client-go repository from a developer's point of view and how to build a Controller with Client-go. At the same time, we also give you a talk about the development process encountered in the pit, I hope everyone in the development of the time can be around
