Network addresses¶
Note
v2 API difference: Addresses now have .proto structure.
SocketAddress¶
{
"protocol": "...",
"address": "...",
"port_value": "...",
"named_port": "...",
"resolver_name": "..."
}
- protocol
- (SocketAddress.Protocol)
- address
- (string) The address for this socket. Listeners will bind to the address or outbound connections will be made. An empty address implies a bind to 0.0.0.0 or ::. It’s still possible to distinguish on an address via the prefix/suffix matching in FilterChainMatch after connection. For clusters, an address may be either an IP or hostname to be resolved via DNS. If it is a hostname, resolver_name should be set unless default (i.e. DNS) resolution is expected.
- port_value
(uint32)
Precisely one of port_value, named_port must be set.
- named_port
(string) This is only valid if resolver_name is specified below and the named resolver is capable of named port resolution.
Precisely one of port_value, named_port must be set.
- resolver_name
- (string) The name of the resolver. This must have been registered with Envoy. If this is empty, a context dependent default applies. If address is a hostname this should be set for resolution other than DNS. If the address is a concrete IP address, no resolution will occur.
BindConfig¶
{
"source_address": "{...}"
}
- source_address
- (SocketAddress, REQUIRED) The address to bind to when creating a socket.
Address¶
Addresses specify either a logical or physical address and port, which are used to tell Envoy where to bind/listen, connect to upstream and find management servers.
{
"socket_address": "{...}",
"pipe": "{...}"
}
- socket_address
-
Precisely one of socket_address, pipe must be set.
- pipe
(Pipe)
Precisely one of socket_address, pipe must be set.
CidrRange¶
CidrRange specifies an IP Address and a prefix length to construct the subnet mask for a CIDR range.
{
"address_prefix": "...",
"prefix_len": "{...}"
}
- address_prefix
- (string, REQUIRED) IPv4 or IPv6 address, e.g. 192.0.0.0 or 2001:db8::.
- prefix_len
- (UInt32Value) Length of prefix, e.g. 0, 32.
