Can not dial tcp localhost:5080

Users Dgraph

I use the following yml file to start alpha:

version: "3.2"
services:
  zero:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data:/dgraph
    ports:
      - 5080:5080
      - 6080:6080
    restart: on-failure
    command: dgraph zero --my=localhost:5080
  alpha:
    image: dgraph/dgraph:latest
    volumes:
      - /tmp/data:/dgraph
    ports:
      - 8080:8080
      - 9080:9080
    restart: on-failure
    command: dgraph alpha --my=localhost:7080 --zero=localhost:5080

but when I run docker-compose up it shows:
