Objectiveto report a recent blockbuster news: the latest version of Ghostcloud Enterprise container Cloud Platform Ecos (corporate Container operation System) has perfectly supported the most mainstream scheduling engine kubernetes in the container market, and officially launched today! Built-in self-research container scheduling framework Newben and open Source engine kubernetes means that the Ecos platfor

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:

First, the prefaceKubernetes is Google's Open source container cluster management system, based on Docker to build a container scheduling services, providing resource scheduling, equalization disaster tolerance, service registration, dynamic expansion capacity and other functional kits, the latest version of the current 0.6.2. This article describes how to build a Kubernetes platform based on Centos7.0, before the formal introduction, it is necessary

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

Note: The following operations are based on the CENTOS7 system.Installing AnsibleAnsilbe can be installed via Yum or Pip, and because Kubernetes-ansible uses the password, it needs to be installed Sshpass:pip install ansiblewget http://sourceforge.net/projects/sshpass/files/latest/downloadtar zxvf downloadcd sshpass-1.05./configure make make installConfigure Kubernetes-ansible# git clone https://github.co

The Cluster Lifecycle layer adds self-hosted functionality to Kubeadm, which means that Kubernetes can be run on Kubernetes, which is bootstrap. Bootstrap is considered to be a system of "elegance" of a embodiment, in fact, Kubernetes in the early attempt to bootstrap, now Kubeadm directly add this feature, is undoubtedly a step closer. In addition, the KUBEADM c

What is the difference between Apache's Mesos and Google's kubernetes? This article comes from a question on the StackOverflow, mainly discusses the difference between Mesos and kubernetes, I believe many of us also have the question of agreeing. Kubernetes's developer Craig answered the question, while Masi also made an overview, not necessarily for the reader's reference.
