[eromoe]

• What version of docker are you running? 1.12

• What version of registrator are you running? lastest

• What is the exact command you are running registrator with?

  docker run -d \
      --name=registrator \
      --net=host \
      --volume=/var/run/docker.sock:/tmp/docker.sock \
      gliderlabs/registrator:latest \
        consul://localhost:8500

• What is the exact command you are running your container with?

  docker run -d \
  -e "SERVICE_NAME=n1" \
  -e "SERVICE_TAGS=master,backups" \
  -e "SERVICE_REGION=fujian_2" \
  -p 8001:80 \
  --name n1 \
  nginx

Description of the problem:

I start two nginx with -e "SERVICE_NAME=n1" and -e "SERVICE_NAME=n2" , but what I got in consul api is n1-80 and n2-80, why it append =80?? I don't want that.

Steps to Reproduce:

1. start consul

   docker run -d \
    -p 8500:8500 \
    -p 8600:53/udp \
    --name consul \
    progrium/consul \
    -server \
    -bootstrap \
    -log-level debug

2. start registrator

   docker run -d \
       --name=registrator \
       --net=host \
       --volume=/var/run/docker.sock:/tmp/docker.sock \
       gliderlabs/registrator:latest \
         consul://localhost:8500

3. start two nginx with name n1 and n2

   docker run -d \
   -e "SERVICE_NAME=n1" \
   -e "SERVICE_TAGS=master,backups" \
   -e "SERVICE_REGION=fujian_2" \
   -p 8001:80 \
   --name n1 \
   nginx
   
   docker run -d \
   -e "SERVICE_NAME=n2" \
   -e "SERVICE_TAGS=master,backups" \
   -e "SERVICE_REGION=fujian_2" \
   -p 8002:80 \
   --name n2 \
   nginx

Actual Results:

curl localhost:8500/v1/catalog/services?pretty
{
    "consul": [],
    "consul-53": [
        "udp"
    ],
    "consul-8500": [],
    "n1-80": [
        "master",
        "backups"
    ],
    "n2-80": [
        "master",
        "backups"
    ]
}

Expected Results:

curl localhost:8500/v1/catalog/services?pretty
{
    "consul": [],
    "consul-53": [
        "udp"
    ],
    "consul-8500": [],
    "n1": [
        "master",
        "backups"
    ],
    "n2": [
        "master",
        "backups"
    ]
}
