In this mode you can point an external load balancer to a UDP port that every Kubernetes node will allocate and translate so it goes to your UDP service. Still, some load balancers (Oracle's OCI is an example) require you to provide a full static request-response UDP conversation that can be used as a way to detect if target nodes are up and running. In that case, you can use `kube-echo` deployed as a `DaemonSet` with a `NodePort` service to use as a Kubernetes node liveness check from the load balancer's perspective. To avoid issues when the `kube-echo` itself goes down or is not running for any reason, it is exposing a simple heart beat prometheus metric you can use for alerting.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpiontec%2Fkube-echo","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpiontec%2Fkube-echo","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpiontec%2Fkube-echo/lists"}
