Docker Cloud自动测试在运行测试后不会退出

Question

我尝试使用Docker Cloud自动将PR测试到my project。我已按如下方式设置构建规则：

Dockerfile：

FROM node:8.4.0-alpine

ENV NODE_ENV=production

WORKDIR /olimat/api

COPY package.json package-lock.json ./

RUN npm install --quiet

COPY ./public ./public
COPY ./config ./config
COPY ./src ./src

CMD npm start

Dockerfile.dev：

FROM node:8.4.0-alpine

WORKDIR /olimat/api

COPY package.json package-lock.json ./

RUN npm install --quiet

COPY ./public ./public
COPY ./config ./config

COPY ./src ./src

COPY ./db ./db

搬运工-compose.test.yml：

version: '3.2'

services:
  sut:
    build:
      context: ./
      dockerfile: Dockerfile.dev
    command: npm test
    depends_on:
      - api
    environment:
      NODE_ENV: test
  api:
    build:
      context: ./
      dockerfile: Dockerfile
    depends_on:
      - db
  db:
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: dev123
    image: postgres:9.6.4-alpine

使用

docker-compose -f docker-compose.test.yml run sut

在本地运行测试一切正常：

在Docker Cloud上，测试运行，但似乎永远不会返回退出代码：

我在这里1小时46分钟后取消了。发生了什么？如何在运行测试后退出 sut 服务容器？
