Hello Play Kafka

Cloud Setup

1. 

2. Install the Kafka plugin into the Heroku CLI

    heroku plugins:install heroku-kafka
   

3. Wait for Kafka to be provisioned:

    heroku kafka:wait -a YOUR_APP
   

4. Add a new Kafka topic:

    heroku kafka:topics:create RandomNumbers --partitions 32 -a YOUR_APP
   

5. Add a new Kafka consumer group:

    heroku kafka:consumer-groups:create main
   

6. Watch the Kafka log

    heroku kafka:topics:tail RandomNumbers -a YOUR_APP
   

7. Check out the random numbers:

    heroku open -a YOUR_APP
   

Local Setup

This uses the same Kafka system as above.

1. Clone the source:

    git clone https://github.com/jamesward/hello-play-kafka
   

2. Associate the local source with your Heroku app:

    heroku git:remote -a YOUR_APP
   

3. Setup a .env file with the necessary info:

    heroku config -s > .env
   

4. Run the web app:

    set -o allexport
    source .env
    set +o allexport
    ./sbt ~run
   

5. Run the worker:

     set -o allexport
     source .env
     set +o allexport
    ./sbt "runMain workers.RandomNumbers"
   

6. Check out the app: http://localhost:9000
