Full Changelog: https://github.com/clusternet/clusternet/compare/v0.12.0...v0.13.0

This release brings Clusternet to a "discovery" world. Clusters creating by cluster-api will be discovered automatically and registered to parent cluster. Auto-labelling for managed clusters is also available now. By integrating mcs-api, multi-cluster services are discoverable and accessible across clusters with a virtual IP.

This release brings in multiple fantastic features and improves the performance. This is a big update of Clusternet. Running clusternet-hub with high availability is possible now. And the performance of clusternet-scheduler is improved as well. Dynamic replica scheduling is fully supported. Applications with multiple replicas can be divided and scheduled to multiple clusters based on cluster dynamic capacity. Please check out this tutorial. Moreover, the aggregated statuses of all deployed resources can be shown by visiting the status of Subscription.

Changes Since v0.10.0

Full Changelog: v0.10.0...v0.11.0

What's Changed

New Features & Enhancements

• Made clusternet-hub high availability (by @dixudx in https://github.com/clusternet/clusternet/pull/378, https://github.com/clusternet/clusternet/pull/405, https://github.com/clusternet/clusternet/pull/411 and by @xrmzju in https://github.com/clusternet/clusternet/pull/387)

The aggregated status of all deployed resources can be shown by visiting the status of Subscription. For every feed/resource, you can check the detailed status (field feedStatusDetails) per cluster and the summarized status (field feedStatusSummary) of all clusters in status.aggregatedStatuses.
• Added new scheduling strategy Dynamic for clusternet-scheduler. Applications with multiple replicas now can be divided and scheduled to multiple clusters based on cluster dynamic capacity. (by @Garrybest in https://github.com/clusternet/clusternet/pull/366, https://github.com/clusternet/clusternet/pull/395, https://github.com/clusternet/clusternet/pull/400, https://github.com/clusternet/clusternet/pull/419). Default predictors run on every clusternet-agent, external predictors had been supported as well (by @yinsenyan in https://github.com/clusternet/clusternet/pull/367 and @dixudx in https://github.com/clusternet/clusternet/pull/418). Learn more from this tutorial.
• Improved the performance of clusternet-scheduler (by @Garrybest in https://github.com/clusternet/clusternet/pull/383, https://github.com/clusternet/clusternet/pull/399, https://github.com/clusternet/clusternet/pull/388)

• Aggregated common labels starting with node.clusternet.io/ from nodes in child clusters (@lmxia in https://github.com/clusternet/clusternet/pull/396, https://github.com/clusternet/clusternet/pull/413). If all nodes of a child cluster have such common labels, then these labels will be aggregated and updated to its corresponding ManagedCluster object.
• Real-time cpu/mem usage and pod statistics can be collected from metrics server by enabling flag --use-metrics-server=true on clusternet-agent side (by @GeorgeGuo2018 in https://github.com/clusternet/clusternet/pull/362, https://github.com/clusternet/clusternet/pull/365 and @DanielXLee in https://github.com/clusternet/clusternet/pull/421)

• Added env for cluster-cidr and service-cidr (by @snstaberah in https://github.com/clusternet/clusternet/pull/391), which would be useful when the kubernetes components were not running as static pods.

Bug Fixes

• Fixed statefulset feedinventory (by @dixudx in https://github.com/clusternet/clusternet/pull/398)
• Removed go routine for storing parent cluster secret (by @DanielXLee in https://github.com/clusternet/clusternet/pull/381)

• Added linter gci (by @dixudx in https://github.com/clusternet/clusternet/pull/397)
• All the docs were migratee to https://clusternet.io (by @dixudx in https://github.com/clusternet/clusternet/pull/409)

Security

• Fixed containerd CVE-2022-31030: A bug was found in containerd's CRI implementation where programs inside a container can cause the containerd daemon to consume memory without bound during invocation of the ExecSync API. This can cause containerd to consume all available memory on the computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to use containerd's CRI implementation; ExecSync may be used when running probes or when executing processes via an "exec" facility. (by @dixudx in https://github.com/clusternet/clusternet/pull/364)

🎉 🎉 🎉 Clusternet Fourth Release !

Clusternet (Cluster Internet) is an open source add-on that helps you manage thousands of millions of Kubernetes clusters as easily as visiting the Internet. No matter the clusters are running on public cloud, private cloud, hybrid cloud, or at the edge, Clusternet lets you manage/visit them all as if they were running locally. This also help eliminate the need to juggle different management tools for each cluster.

Clusternet can also help deploy and coordinate applications to multiple clusters from a single set of APIs in a hosting cluster.

Changes Since v0.3.0

New Features

• provides a two-stage priority based override strategy. Localization and Globalization will define the overrides with priority (ranging from 0 to 1000, default to 500), where lower numbers are considered lower priority. Localization is namespace-scoped resource, while Globalization is cluster-scoped. (by @dixudx in #58,#81 and @qmhu in #61)
  • NOTE: Currently only ApplyLater overrideType is supported, which means these overrides will be applied for all matched objects on next updates (including updates on Subscription, Manifest, HelmChart, etc) or newly created objects.
• reports cluster/service CIDR and cluster node count in ManagedCluster status (by @DanielXLee in #68)
• introduces new feature gate FeedInUseProtection to automatically inject finalizer apps.clusternet.io/feed-protection on new objects and removes corresponding feeds from Subscriptions when deleting objects that do not have finalizer apps.clusternet.io/feed-protection (by @dixudx in #77)
• reconciles and applies resources on agent side - pull mode (by @dixudx in #96)
• allowing customizing ClusterType on cluster regsitration (by @dixudx in #94)

Bug Fixes

• fixes resources listing over all namespaces and filtering over label selectors (by @dixudx in #65, #72)
• When a new cluster is registered, or clusters are re-matched with updated labels, these clusters should be dispatched with all matching Subscriptions. (by @dixudx in #90)

This is the first release of Clusternet, which is aimed to help manage multiple Kubernetes clusters (including public, private, edge, etc) as easily as visiting the Internet.

What's In

Clusternet consists of two components, clusternet-agent and clusternet-hub.

And Clusternet is multiple platforms supported, including linux/amd64, linux/arm64, linux/s390x, etc.

clusternet-agent: runing at each child Kubernetes cluster

• Automatically registers current cluster to a parent cluster as a child cluster
• Reports heartbeats of current cluster, including Kubernetes version, running platform, healthz/readyz/livez status, etc
• Sets up a websocket connection with clusternet-hub in the parent cluster to provide full-duplex communication channels over a single TCP connection

clusternet-hub: running at the parent Kubernetes cluster

• Runs as an Aggregated Apiserver (AA) that maintains multiple active WebSocket connections between child clusters
• Approves registration requests from child clusters
• Creates exclusive set of resources for each child cluster, such as namespaces, service accounts and RBAC rules
• Proxies all Kubernstes-styled APIs to targeted child cluster
• Allows to manage all child clusters (running in private cloud, at the edge, etc) with KubeConfig
