Docker 和 Yaml 发出 Rocket chat

Question

使用 AWS 指南 https://docs.rocket.chat/installation/paas-deployments/aws/ 设置团队聊天 Rocket 聊天

在调整下面的 yaml 代码以匹配我的域之后，我正处于使用 docker 配置的最后阶段。

version: '2'

 services:
   rocketchat:
     image: rocket.chat:latest
     command: >
       bash -c
         "for i in `seq 1 30`; do
           node main.js &&
           s=$$? && break || s=$$?;
           echo \"Tried $$i times. Waiting 5 secs...\";
           sleep 5;
         done; (exit $$s)"
     restart: unless-stopped
     volumes:
       - ./uploads:/app/uploads
     environment:
       - PORT=3000
       - ROOT_URL=https://my.domain.xxx
       - MONGO_URL=mongodb://mongo:27017/rocketchat
       - MONGO_OPLOG_URL=mongodb://mongo:27017/local
     depends_on:
       - mongo
     ports:
       - 3000:3000

   mongo:
     image: mongo:4.0
     restart: unless-stopped
     command: mongod --smallfiles --oplogSize 128 --replSet rs0 --storageEngine=mmapv1
     volumes:
       - ./data/runtime/db:/data/db
       - ./data/dump:/dump

   # this container's job is just to run the command to initialize the replica set.
   # it will run the command and remove himself (it will not stay running)
   mongo-init-replica:
     image: mongo:4.0
     command: >
       bash -c
         "for i in `seq 1 30`; do
           mongo mongo/rocketchat --eval \"
             rs.initiate({
               _id: 'rs0',
               members: [ { _id: 0, host: 'localhost:27017' } ]})\" &&
           s=$$? && break || s=$$?;
           echo \"Tried $$i times. Waiting 5 secs...\";
           sleep 5;
         done; (exit $$s)"
     depends_on:
     - mongo

我收到以下错误并已用尽所有选项：

sudo docker-compose up -d


ERROR: yaml.parser.ParserError: expected '<document start>', but found '<scalar>'
  in "./docker-compose.yml", line 29, column 1

任何帮助将不胜感激，并解释为什么会发生这种情况。

TIA。
