How can I set up a letsencrypt SSL certificate and use it in a Spring Boot application?

Question

I\'m new to securing a server so I don\'t really know much about this but I need to get my Spring Boot Application that is running on a Digital Ocean Droplet to use HTTPS. <

letsencrypt-tomcat queries and refreshes certs via Let's encrypt at runtime (no restarts needed).
It works with standalone and embedded Tomcat as well as Spring Boot.

It's packaged into a Docker image, allowing for easy reuse. The image contains:

• dehydrated to manage certs via Let’s Encrypt,
• tomcat-reloading-connector for hot reloading certs at runtime after renewal,
• an init system (dumb-init) for properly handling tomcat and dehydrated processes,
• an entrypoint script that starts up tomcat and dehydrated as well as
• a pre-compiled version of Apache Portable Runtime (APR) and JNI wrappers for APR used by Tomcat (libtcnative), so tomcat delivers the best TLS performance possible.
