cdc-fraud-detection-demo

Realtime Credit Card fraud detection, using CDC (Change Data Capture) data source and TensorFlow model from a Kaggle competition.

Docker Compose Demo

Prerequisite: At least 6-7GB needs to be provided to your Docker daemon!

Docker compose installation

• Checkout the https://github.com/tzolov/cdc-fraud-detection-demo project and change the local directory to `docker``:

git clone [email protected]:tzolov/cdc-fraud-detection-demo.git
cd cdc-fraud-detection-demo/docker

• Download the Spring Cloud Data Flow Server docker-compose, docker-compose-prometheus and docker-compose-dood installation files:

wget https://raw.githubusercontent.com/spring-cloud/spring-cloud-dataflow/main/src/docker-compose/docker-compose.yml

wget https://raw.githubusercontent.com/spring-cloud/spring-cloud-dataflow/main/src/docker-compose/docker-compose-dood.yml

wget https://raw.githubusercontent.com/spring-cloud/spring-cloud-dataflow/main/src/docker-compose/docker-compose-prometheus.yml

• Make sure that all the docker-compose.yml, docker-compose-prometheus.yml, docker-compose-dood.yml and the docker-compose.fraud.yml files are present in the local directory and then start run:

export COMPOSE_HTTP_TIMEOUT=300
export COMPOSE_PROJECT_NAME=scdf

docker-compose -f ./docker-compose.yml -f ./docker-compose-prometheus.yml -f ./docker-compose.fraud.yml -f ./docker-compose-dood.yml up

• It may take two, three minutes for all containers and services to start. Once ready you should see the following running containers:

docker ps -a

Import Grafana Dashboard

• Open Grafana UI at http://localhost:3000 using the username: admin and password: admin. Skip the request to change the password.

• From the main menu select + and Import:

• Use the Upload Json File button and select the /cdc-fraud-detection-demo/grafana/CreditCardFraudAnalysis.json from the git cloned project.

• Select ScdfPrometheus as data source and press ‘Import’:

This will import a new ‘Credit Card Fraud Analysis’ dashboard and make it accessible via the main menu.

Deploy Spring Cloud Streams

• Open the SCDF Web dashboard at http://localhost:9393/dashboard/#/streams/definitions and navigate to the Stream definitions.

• Press ‘Create New Stream’ button and add the following streams:

fraud-detection=cdc-debezium --cdc.config.schema.whitelist=cdc --cdc.name=my-sql-connector --cdc.connector=postgres --cdc.config.database.user=postgres --cdc.config.database.password=postgres --cdc.config.database.dbname=postgres --cdc.config.database.hostname=postgres-cdc --cdc.config.database.port=5432 --cdc.config.database.server.name=my-app-connector --cdc.flattering.enabled=true | fraud-detection --fraud.detection.processor.model='classpath:/fraud_detection_graph.pb' | analytics --analytics.name=credit --analytics.tag.expression.fraud=#jsonPath(payload,'$..detection')

fraud-log=:fraud-detection.fraud-detection > log

You should see a diagram like this:

• Press Create Stream button.

• Deploy both (fraud-detection and fraud-log) stream. Wait until all apps are deployed

Transaction Generator and Fraud Monitoring

• Open the Credit Card Transaction Generator at http://localhost:8384/generator ,

• Configure the desired transaction rate and fraud ration and press the Start button.

• Open the Grafana Fraud dashboard in another window tab and wait for about 1 min for the first metrics to be recorded.

• You can continually change the card transaction rate and fraud ration and should observe the effect in the dashboard

Kubernetes Demo

Follow the SCDF Kubernetes Installation instructions to install SCDF, Skipper and the remaining components including Prometheus and Grafana

As a shortcut run the following commands from the spring-cloud-dataflow directory:

kubectl create -f src/kubernetes/kafka/
kubectl create -f src/kubernetes/mysql/

kubectl create -f src/kubernetes/prometheus-proxy/

kubectl create -f src/kubernetes/prometheus/prometheus-clusterroles.yaml
kubectl create -f src/kubernetes/prometheus/prometheus-clusterrolebinding.yaml
kubectl create -f src/kubernetes/prometheus/prometheus-serviceaccount.yaml
kubectl create -f src/kubernetes/prometheus/prometheus-configmap.yaml
kubectl create -f src/kubernetes/prometheus/prometheus-deployment.yaml
kubectl create -f src/kubernetes/prometheus/prometheus-service.yaml

kubectl create -f src/kubernetes/grafana/

kubectl create -f src/kubernetes/server/server-roles.yaml
kubectl create -f src/kubernetes/server/server-rolebinding.yaml
kubectl create -f src/kubernetes/server/service-account.yaml

kubectl create -f src/kubernetes/skipper/skipper-config-kafka.yaml
kubectl create -f src/kubernetes/skipper/skipper-deployment.yaml
kubectl create -f src/kubernetes/skipper/skipper-svc.yaml

kubectl create -f src/kubernetes/server/server-config.yaml
kubectl create -f src/kubernetes/server/server-svc.yaml
kubectl create -f src/kubernetes/server/server-deployment.yaml

This will deploy SCDF, Skipper with MySQL and Kafka. Also Prometheus, Prometheus-Rsocket and Grafana are installed

For the CDC Fraud demo add the following additional commands:

kubectl create -f kubernetes/postgres-cdc/
kubectl create -f kubernetes/generator/

Later deploys the Transaction Generator and PostgreSQL-CDC in k8s.

From the SCDF UI Apps register the following apps:

• name: fraud-detection, type: Processor, uri: docker://tzolov/fraud-detection-processor-kafka:latest.

Then follow the Import Grafana Dashboard, Deploy Spring Cloud Streams and Transaction Generator and Fraud Monitoring instructions above.

kubectl delete all,cm,svc -l app=generator
kubectl delete all,cm,svc -l app=postgres-cdc

Test task metrics: docker://tzolov/task-demo-metrics:latest
