Invalid type error in Docker Compose

问题

I am facing error in Docker Compose. The compose file is

version: '2'

services:
  api:
    build:
      context: .
      dockerfile: webapi/dockerfile
    ports:
       - 210
  web:
    build:
      context: .
      dockerfile: app/dockerfile
    ports:
      - 80
  lbapi:
    image: dockercloud/haproxy
    links:
       – api
    ports:
       – 8080:210
  lbweb:
    image: dockercloud/haproxy
    links:
       – web
    ports:
       – 80:80

The error when running docker-compose up is:

ERROR: The Compose file '.\docker-compose.yml' is invalid because:
services.lbapi.ports contains an invalid type, it should be an array
services.lbweb.ports contains an invalid type, it should be an array
services.lbapi.links contains an invalid type, it should be an array
services.lbweb.links contains an invalid type, it should be an array

Please help.

Did you try:

version: '2'

services:
  api:
    build:
      context: .
      dockerfile: webapi/dockerfile
    ports:
       - 210
  web:
    build:
      context: .
      dockerfile: app/dockerfile
    ports:
      - 80
  lbapi:
    image: dockercloud/haproxy
    links:
       – api
    ports:
       – "8080:210"
  lbweb:
    image: dockercloud/haproxy
    links:
       – web
    ports:
       – "80:80"

You should cover ports with brackets because docker-compose expecting string or number in "ports" array but 8080:210 is not a number. See https://docs.docker.com/compose/compose-file/#ports
