An example of how to isolate a docker container from outside influence

Node was used to implement two applications: appA and appB. When opening the appA page, data from appB will be requested

• Application appA forwards port 3000 to the outside and becomes accessible from the outside - the global_network network is used
• The appB application has port 3001, but does not forward the port to the outside

Applications appA and appB are on the same local_network, so they can communicate with each other by name For example appA accesses appB at: http://appB:3001

Repositiory uses docker-compose to build:

docker compose up -d --build

To open the page need to get SERVER_IP where containers are located and follow the link:

SERVER_IP:3000
