Serf parameters for Consul agent configuration files

The page provides reference information for Serf parameters in a Consul agent configuration file.

Serf parameters

• serf_lan - The address to bind to for Serf LAN gossip communications. The value is an IP address that should be reachable by all other LAN nodes in the cluster. By default, the value follows the same rules as bind, and if this is not specified, the value of bind is used. You can dynamically define this parameter with a [go-sockaddr] template that is resolved at runtime. Equivalent to the -serf-lan-bind command-line flag. Do not mistake this parameter for ports.serf_lan.

• serf_lan_allowed_cidrs - Allowed CIDRs to accept incoming connections for LAN Serf from several networks. This parameter supports multiple values. Specify networks with CIDR notation, such as 192.168.1.0/24. Equivalent to the -serf-lan-allowed-cidrs command-line flag.

By default, the value follows the same rules as bind, and if this is not specified, he value of bind is used.You can dynamically define this parameter with a [go-sockaddr] template that is resolved at runtime.
