in October 2013, and in 2015 Google decided to contribute to the core LMCTFY concept and abstracted it into Libcontainer, so lmctfy is no longer active in development.The Lincontainer project was originally initiated by Docker and has now been handed over to the Open Container Foundation (Container).2013-dockerDocker is by far the most popular and widely used container management system. It was originally an internal project of a PaaS service company called DotCloud, which later changed its nam

Direct start:5.1, Flannel IntroductionFlannel is an overlay networking (overlay network) tool designed by the CoreOS team for Kubernetes to help each kuberentes host with CoreOS have a complete subnet. Kubernetes assigns a separate IP address to each pod, which makes it easier for Containers in the same pod to connect to each other, and flannel to set a subnet for the host by creating an overlay grid networ

Kubernetes architecture and component introduction of open-source container Cluster Management System This article is based on an Infoq article (see the reference section) and has been modified based on your understanding in difficult areas. For more information about deploying kubernetes on Ubuntu, see. Together we will ensure that Kubernetes is a strong and open container management framework for any application and in any environment, whether in a private, public or hybrid cloud. --Urs Hölzle
