End current Rails instance from initializer

Question

I am writing a health check initializer that should kill the Rails process if certain properties fail. What would be the safest way to interrupt the production server startup process this way? I believe the extreme case works exit, but I'm not sure if this is the best approach.

Running it on a unicorn, if that matters.

Answer 1

There are three ways to complete the ruby ​​process:

• exit completes the process with status 0 (success).
• exit! 1 ( ), , Kernel#at_exit ( ).
• abort 1 Kernel#at_exit. , ​​ .
