The Docker Compose file is a simple YAML-format file that contains instructions about an isolated system with links to multiple containers. We can also define the environment of each individual container. It is able to start or stop a composite of services with one command. A typical docker-compose.yml file looks like the following:
version: "2"
services:
eureka:
image: doj/eureka-server
ports:
- "8080:8761"
account:
image: doj/account-service
ports:
- "8181:6060"

image: doj/customer-service
ports:
- "8282:6060"
links:
- eureka
