README ¶

lighthouse

Name

Lighthouse - DNS Discovery for services across clusters.

Description

Lighthouse plugin allows Cross Cluster Service Discovery between Kubernetes clusters connected by Submariner.

If the default Kubernetes plugin fails to resolve a DNS request, the lighthouse plugin will try to resolve it using the information it gathered from other clusters that have joined the submariner control plane. On a successful resolution, lighthouse plugin returns the cluster IP of the service in the remote cluster. Submariner ensures that this IP is reachable.

Syntax

Lighthouse requires kubernetes plugin to be present.

Examples

. {
    errors
    log
    kubernetes cluster.local {
      fallthrough
    }
    lighthouse
}
