Spring Cloud Consul and Consul Clients dockerized - spring-boot

Question

I have 2 applications, both written using spring boot. Both are running in different docker containers. I also have consul running in a different docker container. I have exposed port 8500 for consul using docker-compose.yml file. So, how do I specify to my spring boot applications where to register themselves, i.e, where is consul running. Do I give the address of the mapped port (port mapped to my local machine), or some other change?
The example I'm using right now: https://github.com/Java-Techie-jt/cloud-consul-service-discovery
Edit:
docker-compose.yml:
version: "2"
services:
consul:
container_name: consul
image: consul
expose:
- "8300"
- "8400"
- "8500"
restart: always
registrator:
container_name: registrator
image: gliderlabs/registrator:master
volumes:
- "/var/run/docker.sock:/tmp/docker.sock"
command: -internal consul://consul:8500
restart: always
depends_on:
- consul
web1:
image: deis/mock-http-server
container_name: web1
expose:
- "8080"
environment:
SERVICE_NAME: "web"
SERVICE_TAGS: "web"
restart: always
depends_on:
- registrator
web2:
image: deis/mock-http-server
container_name: web2
expose:
- "8080"
environment:
SERVICE_8080_NAME: "web"
SERVICE_8080_TAGS: "web"
restart: always
depends_on:
- registrator
haproxy:
build: ./haproxy
container_name: my-haproxy
image: anthcourtney/haproxy-consul

- 80
depends_on:
- web1
- web2

You can use registrator for your service registry.
Registrator automatically registers and deregisters services for any Docker container by inspecting containers as they come online. Registrator supports pluggable service registries, which currently includes Consul, etcd and SkyDNS 2.
You can run registrator as a container.It will register each port of your application. Below is the sample compose file :-
version: '2'
services:
registrator:
image: "${REGISTRY}gliderlabs/registrator:latest"
command: [
"-ip=<docker-host-ip>",
"-retry-attempts", "100",
"-cleanup",
# "-internal",
"consul://vconsul:8500"
]
