v0.9.0, 21st, October 2022

Open Cluster Management team is proud to announce the release of OCM v0.9.0! Here are some main features included in this release:

  • De-escalate Work Agent Privilege on Managed Clusters In previous iterations of OCM, the Work Agent process is run with admin privileges on managed clusters. This release, to exercise the principle of least privilege, OCM supports defining a non-root identity within each ManifestWork object, allowing end users to give the agent only necessary permissions to interact with the clusters which they manage.
  • Support referencing the AddOn configuration with AddOn APIs For some add-ons, they want to run with configuration, we enhance the add-on APIs to support reference add-on configuration, and in add-on framework, we support to trigger re-rendering the add-on deployment if its configuration is changed
  • Allow Targeting Specific Services within Managed Clusters The cluster-proxy add-on supports the exposure of services from within managed clusters to hub clusters, even across Virtual Private Clouds. Originally all traffic was routed through the Kubernetes API server on each managed cluster, increasing load on the node hosting the API server. Now the proxy agent add-on supports specifying a particular target service within a cluster, allowing for better load balancing of requests made by hub clusters and more granular control of what resources/APIs are exposed to hub clusters.
  • Upgraded ManagedClusterSet API to v1beta2 Update the ClusterSet API and gradually remove legacy custom resources, as well as allow for transformation of legacy resources into analogous v1beta2 resources. v1alpha1 APIs are removed.
  • Consolidate the policy add-on template, status, and spec synchronization controllers into a single repository, governance-policy-framework-addon
  • Application add-on is now able to expose custom Prometheus metrics via the Git subscription. See the metric documentation for more details.

v0.7.0, on 6th, April 2022

The Open Cluster Management team is excited to announce the release of OCM v0.7.0! We mainly focused on enhancing user experience in this release by introducing a bunch of new commands in clusteradm. Notable changes including:

  • APIs including placement, placementdecision, managedclusterset and managedclustersetbinding are upgraded to v1beta1, v1alpha1 version of these APIs are deprecated and will be removed in the future.
  • User can now use clusteradm to:
    • create, bind and view clusterset
    • create and view work
    • check the controlplane status by using hub-info and klusterlet-info sub commands.
    • upgrade hub and klusterlet
  • A default managedclusterset is created automatically and all clusters will be added to default managedclusterset by default. This feature can be disabled with feature gate DefaultClusterSet on registration controller.
  • Add the new policyset API that provides a way to logically group policy objects from a namespace, share placement, and report on overall status for the set in policy addon.

v0.6.0, on 21st, January 2022

The Open Cluster Management team is proud to announce the release of OCM v0.6.0! We made many enhancements on core components and introduced some new addons.

  • First release of cluster-proxy addon, Cluster-Proxy addon is to provide a reverse tunnel from the managed cluster to the hub using apiserver-network-proxy, so user can easily visit the apiserver of the managedcluster from the hub without complicated infrstructure configuration. See here on how to use cluster-proxy in OCM.
  • First release of managed-serviceaccount addon, Managed-Servicesaccount addon provides a mechanism to project a service account on a managed cluster to the hub. The user can then use this projected account to visit services on the managed cluster.
  • Sync status of applied resources in ManifestWork, The users can specify the status field of the applied resource they want to explore in the ManifestWork spec, and get results from the status of the ManifestWork. See here on how to use this feature in Manifestwork.
  • Placement extensible scheduling, a new API AddonPlacementScore is added which allows third party controllers to score the clusters based on various metrics. The user can specify what score should be used in the Placement API to select clusters.
  • Helm chart interface for addon framework, a new interface is added in addon framework with which the developer can build an addon agent from a helm chart. See example on how to build an addon agent from the helm chart.
  • Placement API support for multicloud-operators-subscription, subscription now supports Placement API and can leverage all new features in Placement API to deploy application packages.

We also added many new functions in clusteradm and enhanced the website documentation.
