Docker - Make docker containers use my public ip

Problem

I have a react app running inside a container. I need to request an API(not mine) and it only accepts public IP addresses. Can the container use the public address of my machine?

Docker-compose

version: '3'

services:

client:
  container_name: client
  build:
    context: ./client
    dockerfile: Dockerfile
  volumes:
    - './client:/usr/src/app'
    - '/usr/src/app/node_modules'
  ports:
    - '3000:3000'
  environment:
    - NODE_ENV=development
    - NODE_PATH=src

As to your question: Can the container use the public address of my machine?

Yes, it even does so if you do not specify --net host. You can check that easily using this image (or any other image that contains curl):

First, run this on your host:

curl -s ipinfo.io/ip

This will show your current public IP address.

Then, run the container:

docker run --rm appropriate/curl -s ipinfo.io/ip

It should result in the same IP address.

I don't know anything about React, though, so there might be other stuff going on in your case, but basically this should not be a Docker problem.
