Error 128 at tutorial installation

Hi,

I am new to Grafana and trying to make my first steps with the tutorial. When setting up the tutorial I get an error message.

  • What Grafana version and what operating system are you using?
    v. 12.0.2

  • What are you trying to achieve?
    Installation of tutorial environment

  • How are you trying to achieve it?
    Enter following command into the console:

git clone https://github.com/grafana/tutorial-environment.git
cd tutorial-environment
docker-compose up -d
  • What happened?
    The first two commands are executed without an error, the third caused:
Creating tutorial-environment_grafana_1    ... error

and further below:

ERROR: for grafana  Cannot start service grafana: driver failed programming external connectivity on endpoint tutorial-environment_grafana_1 (9dbb60503d05c46cb7193c8f5a3f65a2855dc08e63e49a6d3cffcb7dc3353d1a): failed to bind port 0.0.0.0:3000/tcp: Error starting userland proxy: listen tcp4 0.0.0.0:3000: bind: address already in use
ERROR: Encountered errors while bringing up the project.

when I enter docker-compose ps I get

tutorial-environment_db_1           /db                              Up         0.0.0.0:8082->80/tcp,:::8082-    
                                                                                >80/tcp                          
tutorial-environment_grafana_1      /run.sh                          Exit 128     
  • What did you expect to happen?
Creating tutorial-environment_grafana_1    ... done

and start the tutorials.

  • Can you copy/paste the configuration(s) that you are having problems with?

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    Could not find one.

  • Did you follow any online instructions? If so, what is the URL?
    Grafana fundamentals | Grafana Labs

Any help would be appreciated.
Thank, Ralf
