    Apache StreamPipes environment is now up and running. Have fun developing!

            Check docs for help:  https://streampipes.apache.org/docs

    If your environment contains the StreamPipes UI, open your browser and follow
    the instructions to get started:
    
    Local Docker for Mac/Windows, Linux:     http://localhost/   
    Remote Docker host:                      http://HOST_IP/
