Introduction to Dragonfly The Dragonfly documentation at https://d7y.io/zh/docs/ already covers things in detail. Here is just a brief introduction to the main components of V2: Manager, which provides the UI, user management, cluster monitoring, task management, and other features Scheduler, which schedules traffic between Peers and provides preheating and other features Seed Peer, the back-to-source node used to download data from origin sites (Harbor, Docker.微信公众号AIDragonflyKubernetesImagesImageNydusConfigurationPracticeOperationshttps://www.chenshaowen.com/en/blog/nydus-configuration-and-practice.htmlSat, 06 Jan 2024 11:22:55 +0000Sat, 06 Jan 2024 11:22:55 +0000https://www.chenshaowen.com/en/blog/nydus-configuration-and-practice.htmlStatistics show that most files inside a container are never used. Based on this characteristic, Nydus defines a custom filesystem in the Rafs format, enabling on-demand loading of image files to solve the slow startup and storage consumption caused by large images. In AI scenarios, whether for inference or training, images often start at several GB, or even tens of GB, so Nydus is very well suited.微信公众号AINydusDockerImagesConfigurationPracticeOperationshttps://www.chenshaowen.com/en/blog/configurate-envoyfilter-in-istio.htmlSun, 12 Nov 2023 00:00:00 +0000Sun, 12 Nov 2023 00:00:00 +0000https://www.chenshaowen.com/en/blog/configurate-envoyfilter-in-istio.html1.

Basic Introduction to Etcd Etcd is a distributed Key/Value storage system. Through distributed locks, leader election, and write barriers it achieves distributed coordination, offering highly available, persistent data storage and retrieval services.
