Docker Container Communication: How-To Guide

Here are some common ways for communication between Docker containers.

1. Using Docker networking: you can create a custom Docker network to connect multiple containers within the same network, allowing them to communicate directly with each other using either the container’s name or IP address.
2. By using the Link feature, you can establish connections between containers by using the “–link” parameter when running the container, allowing you to access other containers using aliases from within the container.
3. By using shared data volumes, multiple containers can mount the same data volume to their file systems, allowing for data sharing.
4. Utilize external services: Connect containers that need to communicate to external services, enabling communication between containers through these external services.
5. Using Docker Compose: Docker Compose is a tool for defining and running multiple Docker containers, enabling communication between containers by outlining dependencies and network connections between services.
