Example app for testing Steveo

It creates a docker app which is using a node application (with running kafka).

Build docker container

• Run docker-compose build app
• Run docker-compose up app

Kafka Engine

Connect to container

• Run docker-compose run app bash

Start kafka producer

root@57f35557fe6b:/usr/src/app# ENGINE=kafka node producer.js

Start Consumer

root@83df25a76b71:/usr/src/app# ENGINE=kafka node consumer.js
initializing consumer [ 'test-topic' ]

You should start seeing messages flowing

SQS Backend

Connect to container

• Run docker-compose run app bash

Start sqs producer

root@57f35557fe6b:/usr/src/app# ENGINE=sqs node producer.js
Produce: Message  1
SQS Publish Data { ResponseMetadata: { RequestId: 'd14d6482-950d-5836-91ff-354e6c715720' },
  MD5OfMessageBody: 'ebae47e466456b6dad60cfc8d04bc510',

  MessageId: '83b29ebc-2c9d-466b-8d35-afb3d1ff2ec6' }

Start Consumer

root@83df25a76b71:/usr/src/app# ENGINE=sqs AWS_ACCESS_KEY=AKAISOMETHING AWS_SECRET_ACCESS_KEY=reallylongs3cr3tk3y node consumer.js

initializing consumer [ 'test-topic' ]
queueURL for topic test-topic is https://sqs.ap-southeast-2.amazonaws.com/hahhahahaha/test-topic
initializing consumer test-topic { MaxNumberOfMessages: 1,
  QueueUrl: 'https://sqs.ap-southeast-2.amazonaws.com/againhahhaha/test-topic',
  VisibilityTimeout: 180,
  WaitTimeSeconds: 20 }
Deleting message test-topic { payload: 'Message 1', timestamp: 1498609468761 }
Start subscribe test-topic { payload: 'Message 1', timestamp: 1498609468761 }
Payload from producer { payload: 'Message 1', timestamp: 1498609468761 }

Redis Backend

Connect to container

• Run docker-compose run app bash

Start redis producer

root@57f35557fe6b:/usr/src/app# ENGINE=redis node producer.js
Produce: Message  1
Redis Publish Data { qname: 'test-topic',
  message: '{"payload":"Message 1","timestamp":1498647318149}',
  delay: 0 } id er852naugvE35vCeVSqCSbx89BVogTW3

Start Consumer

root@83df25a76b71:/usr/src/app# ENGINE=redis node consumer.js

initializing consumer [ 'test-topic' ]
initializing consumer test-topic
