Ports
Internally, Querent will, in fact, use three sockets. The ports of these three sockets
cannot be configured independently at the moment.
The ports used are computed relative to the rest.listen_port port, as follows.
| Service | Port used | Protocol | Default |
|---|---|---|---|
| Http server with the rest api | ${rest.listen_port} | TCP | 1111 |
| Cluster membership | ${rest.listen_port} | UDP | 2222 |
| GRPC service | ${rest.listen_port} + 1 | TCP | 3333 |
In order to form a cluster, you will also need to define a peer_seeds parameter.
The following addresses are valid peer seed addresses:
| Type | Example without port | Example with port |
|---|---|---|
| IPv4 | 172.1.0.12 | 172.1.0.12:7180 |
| IPv6 | 2001:0db8:85a3:0000:0000:8a2e:0370:7334 | [2001:0db8:85a3:0000:0000:8a2e:0370:7334:7180]:1111 |
| hostname | node3 | node3:7180 |
If no port is specified in a peer node address, a Querent node will assume the peer is using the same port as itself.
