Multiple different container all listening 127.0.0.1:80 on the same host machine

Hi, i request your help here because i’m in front of a big trouble :

I have 2 services defined in my docker-compose.yml which are typically two website (i’ll call them web1 and web2) web1 need web2 to work.

I WANT to be able to call web1 via web1.local (hostname pointing on 127.0.0.1) and to call web2 via web2.local (hostname pointing on 127.0.0.1).

I DON’T WANT to be obliged to call web1 via web1.local (hostname pointing on 127.0.0.1) and to call web2 via web1.local:8080 (hostname pointing on 127.0.0.1:8080).

I’m also getting crazy with different network configuration and frustrated by the fact that a simple apache server can make it work but not Docker …

I’ll be thanksfull you give me some help.

Thanks.

no can do… only ONE application can use a port at the same time.

you could use a something like apache or nginx to route a PATH 127.0.0.1/host1 and 172.0.0.1/host2
but you have to provide some different input to select the other app

docker does NOT provide ANY data routing… that is some other apps responsibility

Thanks … pretty boring that this is not possible …

It’s possible. Just have to use some additional software. You could NOT map the ports on to the host and access by ip address (which is what apache or nginx would do)

5

OK, well but what if ip has changed, which could be done randomly on docker …

6

You can set the IP on the docker run to control that. Docker create a network, and then use that and IP address parms

Hi, I got the same problem and solved it with traefik.
I did a reminder here https://github.com/jfm-dnd/docker4php-multiproject - in [fr] sorry - (stuff with docker4php from https://github.com/wodby/docker4drupal/issues/124). Maybe it’ll help ^-^
