* `addresses` - This is a nested object that allows setting bind addresses. For `rpc`
and `http`, a Unix socket can be specified in the following form:
unix://[/path/to/socket];[username|uid];[gid];[mode]. The socket will be created
in the specified location with the given username or uid, gid, and mode. The
user Consul is running as must have appropriate permissions to change the socket
ownership to the given uid or gid. When running Consul agent commands against
Unix socket interfaces, use the `-rpc-addr` or `-http-addr` arguments to specify
the path to the socket, e.g. "unix://path/to/socket". You can also place the desired
values in `CONSUL_RPC_ADDR` and `CONSUL_HTTP_ADDR` environment variables. For TCP
addresses, these should be in the form ip:port.
The following keys are valid:
and `http`, a Unix socket can be specified in the following form
`unix:///path/to/socket`. A new domain socket will be created at the given
path. Any existing socket file (or any other kind of file) at the specified
path will be **overwritten**, so use caution when configuring this argument.
