pass a variable with set_by_lua_file

very simple question for most of you I suppose, but I can't find any answers. I don't know lua at all, I just need this for work :)

I have a line in my nginx.conf like so:

set_by_lua_file $instance_address conf/some_file.lua "user:";

What I need to do basically is set my variable instance_address from my file some_file.lua and also passing the variable user:* for this example. Does this work ? Can I access the variable inside some_file.lua then ? How ?

I've tried with $0, $1, arg[0] and arg[1] but it didn't work

Cheers !

Solution

  • If you want to pass some value to the lua script from nginx configuration, you can set some variable to the required value, e.g.

    set $user "user:";

    and then use it in the lua script via ngx.var.user.
