#### Field Reference
|
|
|
|
|
|
|
|
- `Index` `(int)` - The `Index` value is the Raft corresponding to this
|
|
|
|
configuration. The latest configuration may not yet be committed if changes
|
|
|
|
are in flight.
|
|
|
|
|
|
|
|
- `Servers` `(array: Server)` - The returned `Servers` array has information
|
|
|
|
about the servers in the Raft peer configuration.
|
|
|
|
|
|
|
|
- `ID` `(string)` - The ID of the server. This is the same as the `Address`
|
|
|
|
but may be upgraded to a GUID in a future version of Nomad.
|
|
|
|
|
|
|
|
- `Node` `(string)` - The node name of the server, as known to Nomad, or
|
|
|
|
`"(unknown)"` if the node is stale and not known.
|
|
|
|
|
|
|
|
- `Address` `(string)` - The `ip:port` for the server.
|
|
|
|
|
|
|
|
- `Leader` `(bool)` - is either "true" or "false" depending on the server's
|
|
|
|
role in the Raft configuration.
|
|
|
|
|
|
|
|
- `Voter` `(bool)` - is "true" or "false", indicating if the server has a vote
|
|
|
|
in the Raft configuration. Future versions of Nomad may add support for
|
|
|
|
non-voting servers.
|
|
|
|
|
|
|
|
