karmada - karmada v1.6.0 release

Published by RainbowMango over 1 year ago

What's New

FederatedHPA

Introduced FederatedHPA API to address the requirements that scale workloads across clusters.
FederatedHPA works similarly to HPA in a single cluster. Karmada aggregates metrics from multiple clusters through the karmada-metrics-adaptor component and then scales Pod replicas. The scaled replicas will be distributed to multiple clusters according to the declaration of PropagationPolicy or ClusterPropagationPolicy.

See FederatedHPA Proposal for more details.

(Feature contributor: @chaunceyjiang @jwcesign @Poor12)

Application Failover

In a multi-cluster scenario, the fault may come from the cluster as a whole, or it may be because the application cannot adapt to a certain cluster. Users are now able to declare strategies of application failover about when and how to migrate the unhealthy application in PropagationPolicy and ClusterPropagationPolicy. Karmada will automatically migrate unhealthy applications to other available clusters to improve their availability.

See application-level failover for more details.
(Feature contributor: @Poor12, @RainbowMango)

Karmada Operator

Karmada provides CLI tools and Helm Charts for installation and deployment in previous releases. In this release, the Karmada operator is provided as another declarative deployment method.

The Karmada operator is a method for installing, upgrading, and deleting Karmada instances. It builds upon the basic Karmada resource and controller concepts and provides convenience to centrally manage the entire lifecycle of Karmada instances in a global cluster. With the operator, users can extend Karmada with custom resources (CRs) to manage their instances not only in local clusters but also in remote clusters.

See quick start for more details.
(Feature contributor: @calvin0327, @lonelyCZ, @Poor12)

Third-party Resource Interpreter

Karmada's Resource Interpreter Framework is designed for interpreting resource structure. It consists of built-in and customized interpreters. Karmada has bundled the following open-sourced resources so that users can save the effort to customize them, including Argo Workflow, Flux CD, Kyverno, and OpenKruise. They have been verified by the community.

(Feature contributor: @yike12, @chaunceyjiang, @Poor12)

karmada - karmada v1.5.0 release

Published by RainbowMango over 1 year ago

What's New

Multiple Scheduling Groups

Users are now able to declare multiple groups of clusters to both PropagationPolicy and ClusterPropagationPolicy by leveraging the newly introduced ClusterAffinities field. The scheduler will evaluate these groups one by one in the order they appear in the specification until it finds the one that satisfies scheduling restrictions.

This feature allows the Karmada scheduler to first schedule applications to lower-cost clusters or migrate applications from a primary cluster to backup clusters in the case of cluster failure.

See multiple scheduling group proposal for more info.

(Feature contributor: @XiShanYongYe-Chang @RainbowMango)

New Way to Customize Scheduler

The default scheduler is now able to work with any number of third-party customized schedulers. Similar to Kubernetes, the workloads will be scheduled by the default scheduler if the scheduler name is not declared in PropagationPolicy or ClusterPropagationPolicy.

See customize scheduler for more details.

(Feature contributor: @Poor12)

karmada - karmada v1.4.0 release

Published by RainbowMango almost 2 years ago

What's New

Declarative Resource Interpreter

The Interpreter Framework is designed for interpreting the structure of arbitrary resource types. It consists of built-in and customized interpreters, this release introduced another brand-new customized interpreter.

With the newly introduced declarative interpreter, users can quickly customize resource interpreters for both Kubernetes resources and CRD resources by the rules declared in the ResourceInterpreterCustomization API specification. Compared with the interpreter customized by the webhook, it gets the rules from the declarative specifications instead of requiring an additional webhook component.

The new command named interpret in the karmadactl could be used to test the rules before applying them to the system.
Some examples are provided to help users better understand how this interpreter can be used.

(Feature contributor: @jameszhangyukun @ikaven1024 @chaunceyjiang @XiShanYongYe-Chang @RainbowMango)

PropagationPolicy/ClusterPropagationPolicy priority

Users are now able to declare the priorities for both PropagationPolicy and ClusterPropagationPolicy. A policy will be applied for the matched resource templates if there are no other policies with higher priority at the point the resource template be processed.

The system administrator can use priorities to manage and control policies. Refer to Configure PropagationPolicy priority for more details.

(Feature contributor: @Garrybest @jwcesign)

Instrumentation improvement

This release enhanced observability significantly through metrics and events.
The metrics can be queried by the endpoint(/metrics) of each component using an HTTP scrap, and they are served in Prometheus format. Events are reported to the relevant resource objects respectively.

Refer to events and metrics for more details.

(Feature contributor: @Poor12)

What's New

Taint-based eviction in graceful way

We introduced a new controller named taint manager which aims to evict workloads from faulty clusters after a grace period.
Then the scheduler would select new best-fit clusters for the workloads. In addition, if the feature GracefulEviction is enabled,
the eviction will be very smooth, that is, the removal of evicted workloads will be delayed until the workloads are available on
new clusters or reach the maximum grace period. For more details please refer to Failover Overview.

(Feature contributor: @Garrybest, @XiShanYongYe-Chang)

Global proxy for resources across multi-clusters

We introduced a new proxy feature to karmada-search that allows users to access resources in multiple clusters in a way just like accessing resources in a single cluster. No matter whether the resources are managed by Karmada, by leveraging the proxy, users
can manipulate the resources from the Karmada control plane.
For more details please refer to Global Resource Proxy.

(Feature contributor: @ikaven1024, @XiShanYongYe-Chang)

Cluster resource modeling

To provide a more accurate scheduling basis for the scheduler, we introduced a way to model the cluster's available resources.
The cluster status controller will model the resources as per the customized resource models, which is more accurate than the general resource summary. For more details please refer to Cluster Resource Modeling.

(Feature contributor: @halfrost, @Poor12)

Bootstrap token-based cluster registration

Now for clusters in Pull mode, we provide a way for them to register with the Karmada control plane. By leveraging the commands token and register in kubectl, the registration process including deploying the karmada-agent can be completed very easily. For more details please refer to Register cluster with Pull mode.

(Feature contributor: @lonelyCZ )

Significant improvement in system scalability

We improved the system scalability, such as:

Enable pprof(#2008)
Introduce cachedRESTMapper(#2187)
Adopt the transform function to reduce memory usage(#2383)

With these improvements, Karmada can easily manage hundreds of huge clusters. The detailed test report will be released soon.
