Configure Firefly
This section describes how to configure Trust Domain Servers to use Firefly. For more information about Firefly configuration, see Firefly Configuration Documentation.
You will have to set Client authentication and authorization type to None in Firefly configuration to make it work with Trust Domain Servers over unix domain sockets.

Trust Domain Servers communicate with Firefly over unix domain sockets. Since both Firefly and Trust Domain Servers are deployed as containers in the same pod and unix domain socket is shared over a temporary volume, it is safe to set a client authentication and authorization type to None in Firefly configuration.
