unix socket upstream

[notnooblord]

Hi! Kindly asking, since I failed to find any mention about unix sockets like unix:/tmp/forwarded.sock (without port) being supported in upstreams.

(You can send plain http requests to them since they are essentialy just tcp sockets)

Can anyone confirm and possibly update docs ?

Update:

lua-resty-upstream-healthcheck/lib/resty/upstream/healthcheck.lua

Line 230 in f0b6528

ok, err = sock:connect(name)

it looks like this code is exactly for unix sockets, but not sure.
