Kubernetes api agregátor
Configuring the aggregation layer allows the Kubernetes apiserver to be extended with additional APIs, which are not part of the core Kubernetes APIs. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikube, or you can use one of
Not sure but I think one of the possible way to set these flags could be by editing the yaml of kube-apiserver-xxx pod but when I run: kubectl get po -n kube-system
Extending the Kubernetes API with the aggregation layer; Configure The Aggregation Layer; Horizontal Pod Autoscaling; While the above links go into details on how Kubernetes needs to be configured to work with HPA, a lot of that work is already done for you by kOps. Specifically: Enable the Aggregation Layer via the following kube-apiserver flags:

I mentioned the Kubelet puts the Pod UUID in the filename – this is to enable a plugin to lookup the Pod in the Kubernetes API and enrich the log with Kubernetes metadata. To set this up, you need to add the Kubernetes metadata filter to the fluentd config:

Coming soon: users needing the full set of Kubernetes API semantics can implement their own apiserver and use the aggregator to make it seamless for clients. 2020年12月23日 启用API Aggregator.

The aggregation layer is different from Custom Resources, which are a way to make the kube-apiserver Unlike Custom Resource Definitions (CRDs), the Aggregation API involves another server - your Extension apiserver - in addition to the standard Kubernetes apiserver. The Kubernetes apiserver will need to communicate with your extension apiserver, and your extension apiserver will need to communicate with the Kubernetes apiserver.

For a high level overview, see Extending the Kubernetes API with the aggregation layer. Learn how to Extend the Kubernetes API Using Custom Resource Definitions. Prev - Versions of CustomResourceDefinitions Next - Setup an Extension Aggregation Layer. One of the key pieces which enable exposing the metrics via the Kubernetes API layer is the aggregation layer. The aggregation layer allows installing additional APIs which are In 1.7 the aggregation layer runs in-process with the kube-apiserver.
This arrangement is called API Aggregation (AA). To users, it simply appears that the Kubernetes API is extended. CRDs allow users to create new types of resources without adding another APIserver.

Usually, each resource in the Kubernetes API requires code that handles REST requests and manages persistent storage of objects.
The additional APIs can either be ready-made solutions such as service-catalog, or APIs that you develop yourself. The aggregation layer is different from Custom Resources, which are a way to make the kube-apiserverControl plane component that serves the Kubernetes API. Extending the Kubernetes API with the aggregation layer The aggregation layer allows Kubernetes to be extended with additional APIs, beyond what is offered by the core Kubernetes APIs. The additional APIs can either be ready-made solutions such as service-catalog , or APIs that you develop yourself.

17 Jul 2020 What's next. To get the aggregator working in your environment, configure the aggregation layer. Then, setup an extension api
Usually, each resource in the Kubernetes API requires code that handles REST requests and manages persistent storage of objects. The main Kubernetes API server handles built-in resources like pods and services, and can also generically handle custom resources through CRDs. Setting up an extension API server to work with the aggregation layer allows the Kubernetes apiserver to be extended with additional APIs, which are not part of the core Kubernetes APIs. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.
It registers itself in the main API server through Kubernetes Aggregator and thus is discoverable through the same API endpoint as the rest of Kubernetes under /
