advantages of kubernetes

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

to dispatch. Developers can use declarative syntax to describe inter-container relationships and to schedule cluster management.The atomic project provides a safe, stable, high-performance container operating environment. Atomic contains Kubernetes and Docker, and runs the user using the new software update mechanism ostree.The plan to combine the above three is like. OpenStack developers use their familiar environment for development (LINUX/VAGRANT/

more flexible to specify pod scheduling to the expected node, compared to the nodeselector,affinity and anti-affinity advantages embodied in: More diverse expression syntax, is no longer restricted to forced constraints and matches. The scheduling rule is no longer a mandatory constraint (hard), but is replaced by a soft limit (soft) or preference (preference). Specifies which pods can be deployed under the same/different topologies as the pod. Affin

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

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
