On Jun 21, 2022 KubeEdge released v1.11, introducing several exciting new features and enhancements that significantly improve node group management, mapper development, installation experience, and overall stability.
v1.11 What's New
- Node Group Management
- Mapper SDK
- Beta sub-commands in Keadm to GA
- Deprecation of original
initandjoin - Next-gen Edged to Beta: Suitable for more scenarios
Release Highlights
Node Group Management
Users can now deploy applications to several node groups without writing deployment for every group. Node group management helps users to:
Manage nodes in groups
Spread apps among node groups
Run different versions of app instances in different node groups
Limit service endpoints in the same location as the client
Two new APIs have been introduced to implement Node Group Management:
- NodeGroup API: represents a group of nodes that have the same labels.
- EdgeApplication API: contains the template of the application organized by node groups, and the information on how to deploy different editions of the application to different node groups.
Refer to the links for more details (#3574, #3719).
Mapper SDK
Mapper-sdk is a basic framework written in Go. Based on this framework, developers can more easily implement a new mapper. Mapper-sdk has realized the connection to KubeEdge, provides data conversion, and manages the basic properties and status of devices, etc., as well as basic capabilities and abstract definition of the driver interface. Developers only need to implement the customized protocol driver interface of the corresponding device to realize the function of mapper.
Refer to the link for more details (#70).
Beta sub-commands in Keadm to GA
Some new sub-commands in Keadm have moved to GA, including containerized deployment, offline installation, etc. The original init and join behaviors have been replaced by the implementation from beta init and beta join:
CloudCore will be running in containers and managed by Kubernetes Deployment by default.
Keadm now downloads releases that are packed as container images to edge nodes for node setup.
init: CloudCore Helm Chart is integrated intoinit, which can be used to deploy containerized CloudCore.join: Installing edgecore as a system service from a Docker image, no need to download from the GitHub release.reset: Reset the node, clean up the resources installed on the node byinitorjoin. It will automatically detect the type of node to clean up.manifest generate: Generate all the manifests to deploy the cloud-side components.
Refer to the link for more details (#3900).
Deprecation of original init and join
The original init and join sub-commands have been deprecated as they had issues with offline installation, etc.
Refer to the link for more details (#3900).
Next-gen Edged to Beta: Suitable for more scenarios
The new version of the lightweight engine Edged, optimized from Kubelet and integrated into edgecore, has moved to Beta. The new Edged will still communicate with the cloud through the reliable transmission tunnel.
Refer to the link for more details (Dev-Branch for beta: feature-new-edged).
Important Steps before Upgrading
