No access to Consul UI with "agent -server -bootstrap-expect=1 -ui" parameters

[Stéphane Klein]

This is my docker compose

# docker-compose.yml
version: '2'
services:
  consul:
    image: consul:0.7.1
    command: agent -server -bootstrap-expect=1 -ui
    volumes:
      - ./consul-data/:/consul/data
       
    ports:
      - "8400:8400"
      - "8500:8500"
      - "8600:53/udp"
    expose:
      - "8300"
      - "8301"
      - "8301/udp"
      - "8302"
      - "8302/udp"  
      - "8500"


  whoami1:
    image: emilevauge/whoami
    ports:
      - 80

Next:

$ docker-compose up

I have no access to ui:

$ curl http://127.0.0.1:8500/ui/
curl: (52) Empty reply from server

When I use this docker-compose.yml, without command:

# docker-compose.yml
version: '2'
services:
  consul:
    image: consul:0.7.1
    volumes:
      - ./consul-data/:/consul/data
    ports:
      - "8400:8400"
      - "8500:8500"
      - "8600:53/udp"
    expose:
      - "8300"
      - "8301"
      - "8301/udp"
      - "8302"
      - "8302/udp"  
      - "8500"

  whoami1:
    image: emilevauge/whoami
    ports:
      - 80

Here, I have access to Consul UI:

$ curl http://127.0.0.1:8500/ui/ -I
HTTP/1.1 200 OK

Where is my mistake in the first docker compose? What argument to use to get UI?

Best regards,

Stéphane

You want to add "-client 0.0.0.0" to the command line args - http defaults to listening on 127.0.0.1. By omitting the command you're getting the default arguments for the image, which include that option: https://github.com/hashicorp/docker-consul/blob/master/0.X/Dockerfile#L71.
