Docker / raspberry / noip

General

Hi,

i create a new post to speak about my problem with docker, or instead with opening my multi container applications.

I have 3 containers on my raspberry : 1 nginx, 1 nodejs and 1 mongo. The link between them works well. On each container, i have mentionned the url of the container linked :

  • nginx have the ip adress of node container (ex 192.168.1.99:8888)
  • node have the ip adress of mongo container (ex 192.168.1.99:27017)

In my local network it’s ok, all the links work.

But i would like to put my app public. So i use noip and i configure a new dns like “thisismytest” and my internet box have a redirection on the 80 port to go on my raspberry on the 8080 port (nginx container). This is ok. But in public, the nginx container try to acess to 192.168.1.99:8888 and it’s not available.

How resolve my problem? i am not network expert :slight_smile:

Thanks
