accessing/setting global variables in register_init about haproxy

[Darlelet]

Since 2.9 you may use core.get_var() method to fetch variables from proc.* scope: https://www.arpalert.org/src/haproxy-lua-api/3.0/index.html#core.get_var

For now there is no core.set_var() so you cannot set proc.* variables outside of TXN context, see #2212

However you may set global Lua variables within your script and register custom Lua fetches to return desired values and use the fetch results from haproxy configuration. See https://www.arpalert.org/src/haproxy-lua-api/3.0/index.html#core.register_fetches

In the end there doesn't seem to be an actual bug or issue on haproxy side, thus if you need more assistance to solve your use-case feel to ask for help on the community forum (https://discourse.haproxy.org/) or on the mailing list (https://www.haproxy.org/#tact), some users probably faced similar challenges and may be able to help you.

Hope this helps
