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

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.

As soon as I arrived this morning, I received a "complaint" from my colleague: a node in the Kubernetes cluster on the private cloud seemed to be out of work because the application that was specifically deployed on that node was hung up and was not recovered for a long time. This company private cloud Kubernetes cluster is th
Kubernetes is designed to solve the difficulties of managing a large-scale containerized environment. However, this does not mean that kubernetes can be extended in any environment. There are ways to maximize the scalability of kubernetes, and there are some important things and limitations to be aware of when extending kuber
