Is there way to get access to the source IP address?

[abdolence]

It seems neither via a pseudo header (using get_http_request_headers(...)) nor through something like this get_property(vec!["source", "address"]) is possible to get the source IP address for the HTTP requests.

I'm trying to use Edge Extensions.
Is this some kind of limitation? I didn't find anything in examples or documentation related either (please let me know if I missed some place!).

Not yet supported, but we are working on supporting this via attributes:
https://cloud.google.com/service-extensions/docs/cel-matcher-language-reference#connection_attributes

Actually, for this particular attribute, have you looked at the x-forwarded-for header? This should be added by most proxies including Envoy: https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_conn_man/headers#x-forwarded-for

I am double checking whether we expect to have this in LbEdgeExtensions

Unfortunately not. I will report updates on attributes support in this issue.

x-forwarded-for header

Yes, I checked all headers, there is nothing for the IP, unfortunately.
