federation

The federation middleware enables federated queries to be resolved via the kubernetes middleware.

Enabling federation without also having kubernetes is a noop.

Syntax

federation [ZONES...] {
    NAME DOMAIN

Each NAME and DOMAIN defines federation membership. One entry for each. A duplicate NAME will silently overwrite any previous value.

Here we handle all service requests in the prod and stage federations.

. {
    kubernetes cluster.local 
    federation cluster.local {
        prod prod.feddomain.com
        staging staging.feddomain.com
    }
}

Or slightly shorter:

cluster.local {
    kubernetes
    federation {
        prod prod.feddomain.com
        staging staging.feddomain.com
    }
}
