I'd like to connect several services with a reverse proxy. But the services can't communicate with each others.

I'm using a compose file for each service.

I'm trying to use the same external bridge (icc=false).

After that, I don't understand how to allow the different communication with the reverse proxy. I've tried links and external_links but it doesn't work. Then, I have read that link will be deprecated...

Sorry for my english, I'm not a native speaker. Thanks, have a good day.

#Example of Test1 compose file:
version: '3'
    image: nicolaka/netshoot:latest
    tty: true
    restart: always
      - test2-app-1
      name: bridge_icc_false #created with com.docker.network.bridge.enable_icc=false

icc=false means that inter-container communications are not allowed. If you want to allow inter-container communications, you need to run your containers on a network without this setting.

  • So, should I create one bridge per service ? And the reverse proxy is connected to all bridges ?

  • @Guix555 that's a common design with reverse proxies. The other is to have services that don't talk to each other and you trust on the same network.

  • Thanks @BMitch. This will quickly add several bridges. Is there a maximum ?

  • @Guix555 I think most people run out of private subnet ranges before hitting any other limits. I'm not sure there's a hard limit in docker.
