Node.js Server with Apache
I'm currently using Docker, and i have installed portainer and done tests using httpd etc.
Basically i have a Node.JS server that i want to be running at server.example.com that is restricted to requests from example.com and dev.example.com ( should i do something except using CORS ? ).
I want to use the example.com and dev.example.com websites at port 80.
Meanwhile this i need to restrict access to phpmyadmin and portainer to only be available in localhost too ...
Since i'm a noob at server managament and this is a new world for me yet .. i wonder if something can guide me to what i need to do.
For the restrictions i think i need to use ufw / iptables. but i don't know how i can make this things work together.
