Monitor webpage changes (pixel control is used) and get notified.
For simplicity, you can use docker-compose to start application container and PostgreSQL with default configuration and frontend:
wget https://raw.githubusercontent.com/nikitavbv/ChangeWatcher/master/docker-compose.yaml docker-compose up --build -d
The app will be listening on port 80.
To stop:
docker-compose down
Alternatively, you can use individual container (this requires linking to database container):
docker run --name changewatcher -p 80:8080 --link db:db --env DB_URL=jdbc:postgresql://db:3306/changewatcher --env DB_USERNAME=user --env DB_PASSWORD=password -d nikitavbv/changewatcher
(Database URL and credentials are passed via environmental variables)
