triggering a full stop of nginx service with an error in init_by_lua

alex

I looked through the docs ( and googled ) but I cannot find anything.

I'm using init_by_lua block as a way to configure how the requests are handled.

What I want to do is ability to trigger a full exit of nginx if a certain condition happens inside the init_by_lua block i.e. think of it as catching a configuration error. I do not want to get a stack trace/etc. Just a clean equivalent of doing exit(1).

Any thoughts on how this can be done?

You can do it this way:

        local process = require "ngx.process"
        local resty_signal = require "resty.signal"
        local pid = process.get_master_pid()
        resty_signal.kill(pid, "TERM")

i.e. find out master pid and tell it to kill itself. It will return 128 + "signal that caused process termination".
