plain_tcp_port

This server exposes a plain TCP port that can be chained in front of other servers.

The following common keys are supported:

• listen_in_worker

• ingress_network_filter

listen

required, type: tcp listen

Set the listening socket configuration for this server.

The instance count setting will be ignored if listen_in_worker is correctly enabled.

server

required, type: str

Set the name of the next server that will receive accepted connections.

The next server should be able to accept tcp connections.

proxy_protocol

optional, type: proxy protocol version

Set the PROXY Protocol version expected on incoming TCP connections.

If this is set, connections without a valid PROXY Protocol header are dropped.

Note

The ingress_network_filter option on this server always matches the real socket peer address, not the address carried in the PROXY Protocol header.

default: not set, which means PROXY Protocol is disabled

proxy_protocol_read_timeout

optional, type: humanize duration

Set the timeout for receiving a complete PROXY Protocol header.

default: 5s
