a service) architecture, developers do not care about repetitive tasks like: Authentication, notification, mail services, management and expansion of databases, files, caches, etc. This reduces the development time by half. We use MongoDB and Redis clusters for data storage and NODEJS support for most of our microservices. Cloudboost is fully open source and follows the Apache 2 license Open Source protocol, so you can modify the code and install it on your server for free. GitHub address point

Create a Kubernetes-dashboard In the previous article (SEE), deploy the Kubernetes-dashboard Based on the deployed kubernetes. It is an official user management Kubernets cluster visualization tool; deploying a dashboard is the same as deploying other applications in kubernets. Just create the Replication Controller and Service services required by the dashboard;

If you're an OPS engineer, you know that Docker is valued at more than $1 billion, and Docker is one of the most popular technology brands. Docker containers are known as the de facto standard for container runtimes, but Google's kubernetes is winning the choreography framework market. When using container technology, we often encounter the question, "will using Kubernetes hurt Docker?" ”Many people believe

Mesos and Kuberneteshttp://dockone.io/article/956 I firmly believe that their use will grow faster in the next year, so it is time to review the summary and prepare for 2016 years. I would like to discuss the current situation of Mesos and kubernetes and enumerate the strengths and weaknesses that will allow you to understand the concept of cluster manager.Mesos and KubernetesBefore I start, I'd like to take the time to roughly compare Mesos and

Colleagues who have studied kubernetes know that kubernetes if you need to enable TLS authentication, making a certificate is an essential step. However, many people encounter a lot of trouble in making certificates. Today is the main record of how I made my certificate during the deployment of Kubernetes. Throughout the process, the startup parameters for each c

Tags: WordPress MySQL KubernetesWordPress is the main platform for editing and publishing Web content. In this tutorial, I'll step through how to use kubernetes to build a high availability (HA) WordPress deployment.WordPress consists of two main components: a wordpress PHP server and a database for storing user information, posts, and website data. We need to make these two components in the entire application both highly available and fault tolerant

OverviewCoredns is so notorious because it was introduced from kubernetes1.9 as the default DNS for Kubernetes internal service discovery. There is no doubt that Kubernetes is one of Coredns's backend, so we speak Coredns, starting with Kubernetes as the back end.Many of Coredns's features are mentioned on the web and are not covered here. A simple comparison of

There are several ways to install the Kubernetes cluster, the KUBEADM approach is described earlier, and the manual installation method is described in this article.The installation environment has 3 VMS on Azure:HKUBE01:10.0. 1.4 HKUBE02: 10.0. 1.5 Hbube03: 10.0. 1.6Where hkube01 is the master node, it will install Docker, ETCD, Kubernetes Master, flannel required components;HKUBE02 and hkube03 are worker

In this blog post, let's say a question about customizing the configuration in the pod of kubernetes.We know that in almost all application development, configuration file changes are involved, such as in the Web program, the need to connect to the database, cache, and even queues. And one of our applications starts with writing the first line of code, going through the development environment, the test environment, the pre-release environment only to

Rancher 2.0 is an open-source, enterprise-class Kubernetes platform that is now available for beta releases. Rancher 2.0 simple and intuitive interface style and operation experience, will solve the industry legacy of the long-kubernetes native UI ease of use and the learning curve steep problem. and Rancher 2.0 Creative multi-kubernetes cluster management functi

Controller manager, as the Management control center within the cluster, is responsible for the resource management in the cluster, including node, Pod, namespace, and rated resources. For example, when an unexpected node outage occurs, Controller Manager will promptly discover and perform an automated fix.First, deploy k8s Controller ManagerMake sure Controller-manager-key.pem and Controller-manager.pem exist, and I've created the relevant private key here in the previous article. Perform the f

Kubernetes is Google's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done through the label selector. The function of RC is to ensure service ability and service quality

In the follow-up we will say how to collect pod logs in Kubernetes, when collecting logs, you need to run a log-gathering process on each k8s node, such as Fluentd. We know that under normal circumstances, kubernetes based on its internal scheduling algorithm to automatically assign pods to run on which node, there is no way to ensure that each node runs a fluentd pod. At this time, Daemon sets came in hand
