Add-ons are extended feature packages provided by Tencent Cloud TKE. You can deploy add-ons based on your business requirements. Add-ons can help you manage Kubernetes components in clusters, including component deployment, upgrades, configuration updates, and removal.
Add-on Types
There are two types of add-ons: basic add-ons and advanced add-ons.
Basic add-ons
Basic add-ons are software packages that TKE features depend on. For example, the CLB add-ons Service-controller and CLB-ingress-controller, and the TKE network add-on tke-cni-agent.
Note：
- The upgrade and configuration management of basic add-ons are fully managed by TKE. We recommend that you do not modify basic add-ons.
- When basic add-ons are updated, you will be notified by email and SMS.
Advanced add-ons
Advanced add-ons are optional add-ons provided by TKE. You can deploy such add-ons to use the advanced features supported by TKE. The following table describes the advanced add-ons:
| Add-on | Application Scenario | Add-on Description |
|---|---|---|
| OOMGuard (Out of Memory (OOM) guard) |
Monitoring | This add-on reduces the chance of various kernel failures triggered by cgroup memory reclamation failures in the user mode. |
| NodeProblemDetectorPlus (node exception detection plus) |
Monitoring | This add-on can detect various exceptions on nodes in real time and report the detection results to kube-apiserver. |
| NodeLocalDNSCache (local DNS cache add-on) |
DNS | This add-on runs on cluster nodes as a DaemonSet and as a DNS cache proxy to enhance the DNS performance of clusters. |
| DNSAutoscaler (DNS horizontal autoscaling add-on) |
DNS | This add-on obtains the number of nodes and cores of a cluster through a deployment and then automatically scales the number of DNS replicas according to preset scaling policies. |
| COS-CSI (Tencent Cloud Object Storage) |
Storage | This add-on implements the CSI API to help TKE clusters use Tencent COS. |
| CFS-CSI (Tencent Cloud File Storage) |
Storage | This add-on implements the CSI API to help TKE clusters use Tencent CFS. |
| CBS-CSI (Tencent Cloud Cloud Block Storage) |
Storage | This add-on implements the CSI API to allow you to select the storage class and create the corresponding PVs and PVCs of the CBS type in a TKE cluster on the console. |
| TCR (TCR add-on) |
Images | This add-on automatically configures the private network resolution of domain names and cluster-specific access credentials of the specified TCR instance. It can be used for private-network and secret-free pulling of container images. |
| P2P (accelerated distribution of container images) |
Images | Based on the P2P technology, this add-on can be used to accelerate the pulling of GB-level container images by massive TKE clusters and support concurrent pulling by thousands of nodes. |
| Dynamic Scheduler (dynamic scheduling add-on) |
Scheduling | Dynamic Scheduler is an add-on provided by TKE for pre-selection and preferential selection based on actual node loads. It is implemented based on the native Kube-scheduler Extender mechanism of Kubernetes. After being installed in a TKE cluster, this add-on will effectively prevent node load imbalances caused by the native scheduler through the request and limit scheduling mechanisms. |
| Descheduler (rescheduling add-on) |
Scheduling | After being installed in a TKE cluster, this add-on will work with Kube-scheduler to monitor the high-load nodes in the cluster in real time and drain low-priority Pods. We recommend that you use it together with the TKE Dynamic Scheduler add-on to ensure cluster load balancing in multiple dimensions. |
| NetworkPolicy Controller (network policy controller add-on) |
Others | Network Policy is a resource provided by Kubernetes. This add-on provides a controller for implementing resources of this type. |
| Nginx-Ingress (community Ingress add-on) |
Others | Nginx can be used as a reverse proxy, load balancer, and for HTTP caching. Nginx-ingress is an Ingress controller for Kubernetes that uses NGINX as a reverse proxy and load balancer. |
| OLM (Operator Lifecycle Management) |
Others | OLM (Operator Lifecycle Manager) is part of the Operator Framework, which helps users install, update, and manage the lifecycle of Operators. |
| HPC (modifying the number of replicas periodically) |
Others | HorizontalPodCronscaler (HPC) is an add-on to modify the number of replicas of K8s workload periodically. Used in conjunction with HPC CRD resources, it can support scheduled actions in seconds. |
