Restricting IP Access 8080 port

[CloudStrifer]

Dear Author:
Thank you very much for your work. I quickly set up Bookstack using Docker, but I have a question now. I deployed it in CentOS and enabled a policy to restrict access to port 8080 on the firewall, but it did not take effect.
I have looked into it and it may be related to Docker's network. I added the strategy to docker-compose.yml, but it didn't work. Is there any other way?
Thanks you so much.

Hi,
What are you trying to do?
If you don't want it to be available on port 8080, you can just change the port number before the colon to whatever you want or remove the whole port: block to not publish any ports.
(Though that makes Bookstack completely unavailable.)

Normaly ip/nftables rules for your public interface (typically ethX or enpXsX) should still work, independently of what Docker does.

There is a document from Docker that might be helpful.
