skodjob / debezium-crypto-app

Simple application that consumes updates on cryptocurrencies from coincap to postgreSQL

debezium-crypto-app Project

This project is created for testing purposes only! Core idea behind the application is to create data source that can produce traffic for debezium connector in order to test this connector in long-running environment.

Application creates Rest request to coincap api in the interval configured by property update.period and persist acquired data to PostgreSQL database (default database name is debezium_crypto). Version of the database can be from 11-15 as Debezium support matrix indicates.

Running the application in dev mode

Before you can run the actual app you have to deploy the database. There is prepared docker image for you. You can run the database as:

cd database
docker build -t tealc-postgres:latest .
docker run --name postgresql -e POSTGRES_USER=test -e POSTGRES_PASSWORD=test -p 5432:5432 -v /tmp/postgresql/:/var/lib/postgresql/data -d tealc-postgres:latest

Keep in mind that your username and password must be the same that you pass to debezium-crypto application. You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

Packaging and running the application

This application can be build as native image:

./mvnw package -Pnative -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true

Once native image is build you can build docker image from that as:

docker build -f src/main/docker/Dockerfile.native -t quay.io/tealc/debezium-crypto-app .

After image is build you can start the container like this:

docker run --name app -p 127.0.0.1:8080:8080 quarkus/debezium-crypto-app ./application "-Dquarkus.http.host=0.0.0.0" "-Dupdate.period=2s" "-Dquarkus.datasource.jdbc.url=jdbc:postgresql://${CONTAINER_IP_OR_HOST}:5432/debezium_crypto"
