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
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

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
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

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

The game engine is the same thing, the game developer completes the detail work, makes the game looks real, attracts the eyeball. The game engine is responsible for the rest of things. In the early days, game developers were often made from sketches, expensive, and not easily profitable. To make game deve

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.
