Docker enables more convenient management of single-machine container virtualization, where Docker is located between the operating system layer and the application layer; Relative traditional virtualization (Kvm,xen):Docker can be more flexible to implement some of the application layer functions, while the utilization of resources is also higher Relative application:Docker can better combine applications with more operating systems (mirroring), reducing the cost of deployment and

Alena Prokharchyk, Chief software engineer at Rancher Labs, was invited to give a presentation at the Kubernetes + Kubecon 2017 North American Summit, hosted by CNCF in December 2017 6-8th. This article is organized by the content of the lecture.As Kubernetes is becoming more and more popular, the number of integration and monitoring services around it is growing. The key component of all such services writ

As Kubernetes began to use more and more companies, more teams and lines of business within the company began accepting or proactively learning about Docker, and in order to address the existence of first-generation platforms and the deployment of existing services based
Platform Environment: Centos 7.0First, the architecture modeSecond, Core ServicesMaster1) ETCD ServiceETCD is a highly available key-value storage system that Kubernetes uses to store the state of individual resources, enabling restful APIs. The ETCD service acts as the primary database for the Kubernetes cluster and needs to be installed and started before installing K
network model by Openvswitch GRE, but this approach is a bit clumsy in large-scale systems. For example, if the system has n hosts and they need to communicate between them, an n (n-1)/2 GRE tunnel is required, although it is possible to prevent the bridge loop by enabling the SPT protocol, but maintaining N (n-1)/2 tunnels is still a lot of work. So next consider how you can automate the implementation.4. References Https://github.com/GoogleCloudPlatform/
Kubernetes API Server FeaturesThe core function of Kubernete API server is to provide an HTTP rest interface for kubernetes, deleting, changing, checking, and watch for various resource objects (such as Node,pod,service, etc.).The API server is the central hub for data interaction and communication between the various functional modules in the cluster, in addition to the following features: API Por
CoreOS Linux introduced the Kubernetes KubeletKelsey HightowerAugust 14, 2015This week we have integrated a core embedded component of kubelet--kubernetes in the Alpha development of CoreOS Linux. Kubelet is responsible for maintaining the pod (application instance) collection. The Pod collection consists of one or more containers of the local system. In the Kubernetes

I. Introduction:Kubernetes is an open source container management tool, based on the Go language implementation, lightweight and portable applications, you can put kubernetes cluster on the Linux host deployment, management and expansion of the Docker container application on multiple hosts.Two. Architecture: 1. The kubernetes consists of the following components:

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 kubernetes use Glu

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 container clusters through kubernetes clusters
From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed. Scheduling speed encountered bottlenecks, affecting the deployment of large business speed. There is no good support for stateful services. There are two solutions to this problem, one for improved refactoring of ex

Use Kubernetes step by stepWhy Docker and Kubernetes? Containers allow us to build, publish, and run distributed applications. They free applications from machine restrictions and allow us to create a complex application in a certain way. Writing applications using containers can bring development and QA closer to the production environment (if you try to do so ). By doing so, you can publish changes faster
