Run the MongoDB microservice on Docker and KubernetesGuideDocker is an open-source application container engine that allows developers to package their applications and dependencies to a portable container and then publish them to any popular Linux machine, you can also achieve virtualization. Containers fully use the sandbox mechanism and do not have any interfaces between them.
This article describes how to use Docker and Kubernetes to build a set
Kubernetes Cluster Deployment DNS ServiceIn Kubernetes each service will be assigned a virtual IP, each service under normal circumstances will not change for a long time, this is relative to the pod of the indefinite IP, the use of the cluster app is relatively stable.But the service's information injected into the pod is currently using an environment variable, and relies heavily on pod (RC) and service c

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

Article, where the information may have evolved or changed.
"Editor's words" This share is mainly zookeeper, Redis, Kafka, MongoDB and other applications containerized in the Kubernetes platform above practice. The problems of application in integration are analyzed from the aspects of computing, network and storage, and the application of some traditional applications in the process of container design is two times.

Welcome to an in-depth study of the Kubernetes API Server series, in this series of articles we will delve into the implementation of Kubernetes API server. This series of articles can help you if you are interested in Kubernetes's internal implementation mechanisms or are working on the development of kubernetes projects. Learning to learn the go language will h
Recently, Bocloud Boyun novel formally received the CNCF and Linux Fund certified Kubernetes Service Provider qualification (KCSP), which proves Bocloud Boyun novel activities in the Kubernetes community (including active contribution code), business model supporting enterprise end users , as well as the presence of engineers on the site of the three sides have the corresponding technical strength.The KCSP
This article introduces the use of Docker and kubernetes to build a set of MONGODB services with redundant backup sets, from the container to the CI and CD-initiated changes, discussed the container technology to MONGODB challenges and opportunities, and then how to deploy a stable set of MONGODB services , very dry.IntroducedWant to try to run MongoDB on your laptop? Want to execute a simple command and then have a lightweight, self-organizing sandbo
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
Configure the dashboard service for a Kubernetes Cluster
This article describes how to create and use kube-ui (also called dashboard) based on the previous article. This is essentially an api interface for connecting webui to the master. It obtains information about the k8s cluster through the api and then displays it on the web, which is more friendly to users, it is not very useful.

Here the ETCD cluster is multiplexed with the 3 nodes that we tested, 3 node to install and start, note to modify the configuration file1, TLS certification file distribution: ETCD cluster authentication, in addition to the native, distributed to other node nodesSCP ca.pem KUBERNETES-KEY.PEM Kubernetes.pem [email protected]10.10. 90.106:/etc/kubernetes/SSLSCP ca.pem KUB
Kubernetes ArchitectureThe overall architecture of the kubernetes is as follows:Master is the main control node, which runs Apiserver,scheduler,controller-manager and other components. Minion is the equivalent of a working node, which runs Kubelet,proxy,cadvisor and the most important Docker components. Here's how to actually deploy this cluster management tool.EnvironmentYy1 10.193.6.35Yy2 10.193.6.36Yy1 a
1. Bash Auto-refill for KUBECTL commandsThis is probably the easiest thing to do in the kubernetes process, but it's also one of the most useful. To add the auto-refill feature, if you use bash, simply execute the following command:echo"sourceIt will add an auto-complete command to your. bashrc file. So each shell window you open supports this feature. I found that auto-completion is especially useful for some long parameters, such as--all-namespaces.

Helm IntroductionDeploying container cloud Applications (container or microservices orchestration) in Kubernetes is a challenging task, Helm is to simplify the installation of a client tool for deploying container cloud applications in Kubernetes. Helm enables developers to define, install, and upgrade container cloud applications in Kubernetes. At the same time,
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
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.
