Connecting Containers with Docker Compose Networks
Use Docker Compose to define multi-container apps and let them communicate over an automatically created bridge network using service names.
Why Compose for Networking
Running many containers and wiring their networks by hand is tedious. Docker Compose describes your whole stack in one YAML file and creates a dedicated network so services can find each other.
The Default Compose Network
When you run docker compose up, Compose creates a single user-defined bridge network for the project. Every service joins it automatically, so no manual docker network create is needed.
