# Streaming (spring spring-cloud-stream kafka)

Greater -> (messages) -> GreatingHandler -> (uppercased) -> Doubler -> (transformed) -> LogReceiver

```bash

gradle composeUp

gradle Greater:bootRun

gradle MessageReceiver:bootRun

gradle UpperCaser:bootRun

gradle Doubler:bootRun

gradle Logger:bootRun

gradle composeDown

gradle --stop

```

run all together for integration tests

```bash

gradle clean build

```

for testing run in order:

- kafka using docker-compose (read below)

- GreaterApplication

- UpperCaserApplication

- DoublerApplication

- LoggerApplication

- LogReceiverApplication (another logger)

_run kafka in docker-compose_

```bash

# git clone --depth=1 https://github.com/confluentinc/cp-docker-images.git

# docker-compose -f cp-docker-images/examples/kafka-single-node/docker-compose.yml up -d

# docker-compose -f cp-docker-images/examples/kafka-single-node/docker-compose.yml down -v --rmi local

## or already cloned locally:

# docker-compose -f kafka/kafka-single-node/docker-compose.yml up -d

# docker-compose -f kafka/kafka-single-node/docker-compose.yml down -v --rmi local

## or:

# docker-compose up -d

# docker-compose down -v --rmi local

## or just:

./gradlew composeUp

./gradlew composeDown

```
