hello could anyone help me how to install or any images via docker?
I try to install paperclip on docker but don't really understand how.
These are the steps i already taken:
- i pull the images

- i create container from the image i pull and set port local port: 3000, container port: 3000 TCP


- then i add domain my domain like this

but when i try to access paperclip.mydomain:3000 it got This site can’t be reached error
i already pointed the sub domain name using cloudflare to aapanel server IP address and turn on proxy in CF
where did i do wrong? anyone can help?
thanks before
