I'm building an application using Docker, which includes a MySQL database, an Angular front-end with Nginx, and a Spring Boot backend for API calls. Currently, everything is running fine in separate images through Docker Compose, but all of my services are using HTTP. I need help figuring out how to set this up to work with HTTPS. Just to add some more context: I do have Nginx set up as a reverse proxy to facilitate communication between Angular and Spring. This application is intended for internal use, so it will be accessed using the host computer's IP address, which is 192.168.0.100.

You might want to look into using a reverse proxy like Caddy, Nginx, or Traefik. They're great for handling HTTPS, and Caddy is super user-friendly because it automates SSL certificates for you. For example, a simple Caddy config can just look like this:
```
mydomainname.com {
reverse_proxy localhost:5000
}
```
It handles SSL certs through Let's Encrypt automatically, and all you need to do is ensure your DNS is set up correctly pointing to your server's public IP. Just make sure ports 80 and 443 are open for incoming traffic.
Since your application is internal, remember to tweak Nginx's configurations to serve HTTPS using the certificates. It's essential to familiarize yourself with the basics of Nginx and SSL if you're not already. Getting those fundamentals down will help you set everything up correctly.
Nginx can easily manage HTTPS for your application. You just need to configure it to listen on port 443 and properly set up your SSL certificates. A good practice is to set port 80 to redirect to HTTPS, so everyone uses a secure connection, regardless of how they access it.
If you're looking for a straightforward solution, just ensure your reverse proxy (whether Nginx or another) is set to accept that traffic and can handle TLS termination. This way, both your Angular front-end and Spring Boot backend can be accessed securely.
Definitely check out the setup guides that match your stack. You can find useful resources online to walk you through the process, like the Simplesteps guide for setting up a Caddy server.
