Problem Statement
In Docker Compose, which keyword is used to assign an alias to a service within a network so other services can refer to it by that alias?
Explanation
In a docker-compose.yml file, you can define networks and within a service use the key `networks: { yournet: { aliases: ["myalias"] } }`. This alias then lets other containers refer to the service by that name. It improves readability and decouples service names from container names.
