Hi,
Nice and informative.

Appreciate if you can also do a video explaining how the port mapping works internally like how the host's network configurations are modified such that request reach to the container. I was specifically looking for this information and i did not find any video explaining the internals of the port forwarding.


Thanks,
K

This video is very beginner-friendly. I am just facing a very strange thing with my docker container as I am running two different containers, one with bitwarden server running on port 8080:80 and other is nextcloud assigned with ports 8443:43. Now, the bitwarden container is working without any problem but when I try to open nextcloud on my local machine, it wont work. The ports are binded successfully but the server is not connecting. When I used "curl"command with curl localhost:8443, it responded me as connection time out. Please help. Thanks in advance
