Does postgres start automatically in the pipeline?

[Devlin Pajaron]

I keep getting the following error on the `npx lerna run migration:run` command which connects to postgres.

{ Error: connect ECONNREFUSED 127.0.0.1:5432    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1097:14)  errno: 'ECONNREFUSED',  code: 'ECONNREFUSED',  syscall: 'connect',  address: '127.0.0.1',  port: 5432 }

 My bitbucket pipeline looks like this

image: node:10.15.3
options:
  max-time: 20

definitions:
  services:
  docker:
    memory: 2000
  postgres:
    image: postgres
    restart: always
    environment:
      POSTGRES_DB: 'db'
      POSTGRES_USER: 'postgres'
      POSTGRES_PASSWORD: 'test'
  steps:
    - step: &install-deps
        name: Prepare node_modules
        caches: *app-caches
        script:
          - npx lerna bootstrap --hoist
          - npm i -g ts-node typescript
          - npx lerna run migration:run
          - npx lerna run seed
pipelines:
  default:
    - step: *install-deps
      services:
        - postgres
