I am trying to let haproxy access my letsencrypt ssl certs easier.

I am using haproxy 1.8 ( octopi setup )

I added a lua-load command to my global config section in my haproxy.cfg file. I used:  
lua-load \<path\_to\>/update\_haproxy\_ssl\_certs.lua  
and that lua script copies / merges the required ssl certs from my /etc/letsencrypt directory to the place / file that haproxy wants.

That all works great.

My question / issue is… can I have that lua-load command there and NOT fail if the file it wants to load does not exists. Can I have some sort of:

if file\_exists(\<path\_to\>/update\_haproxy\_ssl\_certs.lua) {  
lua-load \<path\_to\>/update\_haproxy\_ssl\_certs.lua  
}  
or  
lua-load-if-file-exists \<path\_to\>/update\_haproxy\_ssl\_certs.lua

The haproxy.cfg file is copied to multiple servers… but they don’t all have the letsencrypt ssl certs.

- thanks - jack

No, this is not possible. You need to automate this yourself.
