## Services address and port configuration
## Services/node address and port configuration
Version 0.100.0 of NeoGo introduces a multiple binding addresses capability to
the node's services (RPC server, TLS RPC configuration, Prometheus, Pprof)
that allows to specify several listen addresses/ports using an array of
"address:port" pairs in the service `Addresses` config section. Deprecated
`Address` and `Port` sections of `RPC`, `Prometheus`, `Pprof` subsections of the
`ApplicationConfiguration` as far as the one of RPC server's `TLSConfig` are
still available, but will be removed, so please convert your node configuration
file to use new `Addresses` section for node services.
the node's services (RPC server, TLS RPC configuration, Prometheus, Pprof) and
the node itself. It allows to specify several listen addresses/ports using an
array of "address:port" pairs in the service's `Addresses` config section and
array of "address:port:announcedPort" tuples in the `ApplicationConfiguration`'s
`Addresses` node config section. Deprecated `Address` and `Port` sections of
`RPC`, `Prometheus`, `Pprof` subsections of the `ApplicationConfiguration`
as far as the one of RPC server's `TLSConfig` are still available, but will be
removed, so please convert your node configuration file to use new `Addresses`
section for the node services. Deprecated `Address`, `NodePort` and `AnnouncedPort`
sections of `ApplicationConfiguration` will also be removed eventually, so please
update your node configuration file to use `Addresses` section for the P2P
addresses configuration.
Removal of these config sections is scheduled for May-June 2023 (~0.103.0 release).
