Hi, I have some code that I would like to run during the configuration loading phase of Kong. To setup variables and stuff that I need.
In Openresty this configuration sample gets loaded without an issue, In Kong however the init\_by\_lua\_block in my extra configuration causes start up issues of the Kong service.
It seems like both the default Kong configuration has its own `init_by_lua_block` and my extra configuration has one as well confusing Kong? How can get my extra `init_by_lua_block` to exist side by side with the default Kong configuration?
Note: I am using Kong version 1.3.0rc1-alpine docker image because I want to use the grpc directives from Openresty.
```auto

Sample extra configuration file to be loaded when Kong starts
```auto
lua_code_cache off;
init_by_lua_block {
-- Define global import paths
PROTOC_IMPORT_PATHS = {
"/usr/local/protoc/include"
}
}
server {
listen 8000;
server_name localhost;
location /rest {
access_by_lua_block { SOME_CODE}
body_filter_by_lua_block {SOME_CODE}
grpc_set_header Content-Type application/grpc;
grpc_pass app:50051;
}
}
```
Is it not possible to have `init_by_lua_blocks` in the extra included configurations?

This is not possible.
You will have to create a custom Nginx template and then pass it to Kong.
