I am a DevOps brand new to Apache/Tomcat. I am taking on a task to refresh company's 15 year old website in a Docker setup. It is all fine until I get to the SSL part.

the setup:
--One Tomcat that host the front-end web application, it's all just web pages, sending request to back-end load-balancer, no SSL, no keystore loaded.

--One Apache Load-balancer handles request from front-end, pass through ajp to back-end workers. SSL cert and keys are loaded here. Logic is load-balancer will handles security check and simply pass the request onto workers, workers don't need to load SSL anymore.

--Four instance of workers actually takes request from load-balancer. no SSL, no keystore loaded.

My problem is, the old website wasn't setup correctly in terms of certificate (self-signed). We are trying to do it right (got godaddy cert) but I have no idea how it should be done. So I don't even know whether my current SSL setup is correct or not. Does front-end Tomcat needs to load a keystore file in Connector? Does each back-end workers need to load keystore file in Connector?

I am so new I am not even sure my questions make senses or not please be a little patient with me.

Thanks, please help.
