# socat-tunneller

A `port-forward` proxy. Allows an onward connection from the cluster
to some other host in your cluster's network, eg your hosted
database/cache/other service.

In practice, this means that a hosted service can be made available
only to the cluster, then cluster users can be granted access by
giving them permission to run `port-forward` on the tunneller.
