Bugs

  • Fix statefulset inplace update fields in pod metadata such as labels/annotations.

v0.3.1**

Installation

  • Simplify installation with helm charts, one simple command to install kruise charts, instead of downloading and executing scripts.

  • Support priority update, which allows users to configure the sequence for Pods updating.

Bugs

  • Fix maxUnavailable calculation, which should not be less than 1.

Broadcast Job

Bugs

  • Fix BroadcastJob cleaning up after TTL.

v0.3.0**

Installation

  • Provide a script to check if the K8s cluster has enabled MutatingAdmissionWebhook and ValidatingAdmissionWebhook admission plugins before installing Kruise.
  • Users can now install specific controllers if they only need some of the Kruise CRD/controllers.

Kruise-Controller-Manager

Bugs

  • Fix a jsonpatch bug by updating the vendor code.

Advanced StatefulSet

Features

  • Add condition report in status to indicate the scaling or rollout results.

A NEW workload controller - UnitedDeployment

Features

  • Define a set of APIs for UnitedDeployment workload which manages multiple workloads spread over multiple domains in one cluster.
  • Create one workload for each Subset in Topology.
  • Manage Pod replica distribution across subset workloads.
  • Rollout all subset workloads by specifying a new workload template.
  • Manually manage the rollout of subset workloads by specifying the Partition of each workload.

Documents

  • Three blog posts are added in Kruise website, titled:
    1. Kruise Controller Classification Guidance.
    2. Learning Concurrent Reconciling.
    3. UnitedDeploymemt - Supporting Multi-domain Workload Management.
  • New documents are added for UnitedDeployment, including a tutorial.
  • Revise main README.md.
