Some of the technology frontier companies first-step practice is probably the most persuasive and reference value. This article is a good reference.1Kubernetes now rage, it is part of a massive cloud-native movement. All major cloud providers use it as a solution for deploying cloud-native application
The Kubernetes network model is made up of four parts from inside to outside:
The network where the pod interior container resides
The network where the pod resides
Network for communication between pod and service
Network of communication between outside and service
It is recommended that you understand the network model of Docker before reading this article. Refer to the author's first two articles [
package dependenciesKubernetes is a platformKubernetes has a lot of popular places. Users like its rich functionality, stability, and performance. For contributors, the Kubernetes open source community is not only large, but also easy to get started and quick to respond to. What really makes kubernetes attractive to third-party developers is its extensibility.

Here we look at industry scenarios and related concepts.

have a lot of physical resources and want to build a huge, static computing cluster. There are many modern scalable data processing applications that can be run on Mesos, including Hadoop, Kafka, Spark, and so on, while you can use container technology to run all your data processing applications in a pool of underlying resources. In some ways, Mesos is a more heavyweight project than Kubernetes, but thanks to Mesosphere-like

. Participate There's a lot of exciting work to do in the near future. We are actively studying such functions as dynamic resource allocation, dependency clustering, support for PYSPARKSPARKR, support for the kerberized HDFs cluster, and client-side mode and the interactive execution environment of popular notebooks. For those who fall in love with Kubernetes's way of managing applications declaratively, we are also committed to kubernetes operat
