#Docker #Network #Container
Within your Dockerfile you have to EXPOSE the ports that you want to use e.g. EXPOSE 8080 on NGINX. Afterwards, you can define your own network in the docker-compose.yml file therefore you need to define the network e.g. some-network and provide a subnet range like 172.20.0.0/16. Afterwards you can assign the IPs you would like towards your services in the docker-compose.yml file. As you showed, the network section is already implemented, you just need to adjust it. Firstly change the default name towards your newly defined network name ( some-network ) and as a subsection of that you can add a e,g, ipv4_address: 172.20.0.5. Afterwards this container is reachable under 172.20.0.5:8080. This information can be used as information channel of your application. An example can be found here https://docs.docker.com/compose/networking/
FROM continuumio/miniconda3
...
EXPOSE 8080
docker-compose.yml:
...
nginx:
image: nginx
container_name: "nginx"
build:
context: ..
dockerfile: docker/nginx/Dockerfile
restart: always
networks:
some-network:
ipv4_address: 172.20.0.5
networks:
some-network:
config:
- subnet: 172.20.0.0/16

Configure a Bridge network between Docker container
Currently I try to configure the network between two Docker Container. On the first container my application is running, on the other Container a simple NGINX server is running. I would like to give both a static IP so that I am able to test the communication.
The current application and NGINX Dockerfile looks as follows:
FROM continuumio/miniconda3
WORKDIR /app
COPY ./application /app
RUN apt-get update -y && apt-get install -y gcc
RUN conda env create -f environment.yml
RUN echo "source activate aic_env" > ~/.bashrc
ENV PATH /opt/conda/envs/aic_env/bin:$PATH
CMD ["python3","src/main.py"]
The docker-compose.yml looks like this:
version: '3.7'
services:
application:
image: application
container_name: "application"
build:
context: ..
dockerfile: docker/application/Dockerfile
networks:
default
nginx:
image: nginx
container_name: "nginx"
build:
context: ..
dockerfile: docker/nginx/Dockerfile
restart: always
networks:
default
What do I need to do for a communication between both containers on a static IP under port 8080 ?
