15 Endpoint Copier Operator

 

Endpoint Copier Operator is a Kubernetes operator whose purpose is to create a copy of a Kubernetes Service and Endpoint and to keep them synced.

15.1 How does SUSE Telco Cloud use Endpoint Copier Operator?

 

At SUSE Telco Cloud, the Endpoint Copier Operator plays a crucial role in achieving High Availability (HA) setup for K3s/RKE2 clusters. This is accomplished by creating a kubernetes-vip service of type LoadBalancer, ensuring its Endpoint remains in constant synchronization with the kubernetes Endpoint. MetalLB (Chapter 14, MetalLB) is leveraged to manage the kubernetes-vip service, as the exposed IP address is used from other nodes to join the cluster.

15.2 Best Practices

 

Comprehensive documentation for using the Endpoint Copier Operator can be found here.

Additionally, refer to our guide (Chapter 19, MetalLB on K3s (using Layer 2 Mode)) on achieving a K3s/RKE2 HA setup using the Endpoint Copier Operator and MetalLB.

15.3 Known issues

 

Presently, the Endpoint Copier Operator is limited to working with only one Service/Endpoint. Enhancements to support multiple Services/Endpoints are planned for the future.
