🎉🎉🎉 This is the first release of SuperEdge!

This release includes 5 core features to transform a Kubernetes cluster to an edge-native container management system for edge computing.

Features

Tunnel

• Proxies requests from master nodes to edge worker nodes, which allows accessing edge nodes with no public IP address.
• It is enabled by default for request from kube-apiserver to Kubelet on the Edge Worker nodes.
• Supports TCP/HTTP/HTTPS.

ServiceGroup

• Enhanced application management on the edge by grouping related applications and edge worker nodes.
• Offers two new CRDs for managing serviceGroup - DeploymentGrid & ServiceGrid.
• Provides isolated internal network for applications inside the same serviceGroup.

Edge Autonomy

• Keeps services on the edge nodes up and running stably despite of network disconnection between edge and cloud.
• Allows pods on the edge to restart correctly even though losing connection to the master kube-apiserver.

EdgeHealth

• Enhanced monitoring of edge worker nodes.
• Distributed health check on groups of edge nodes.
• Determines status of the node based on the status checks from nodes within the same health check group.
• Eliminates false alert in case of losing cloud-to-edge network connection.

EdgeAdm

• EdgeAdm is a command-line tool to help users to deploy SuperEdge to native Kubernetes in 1-click.
