#Docker Compose I have practiced docker-compose during SonarQube integration with Jenkins, the initial docker compose file lies in CI-CD Learning repository, In that docker-compose.yml used to launch two containers one for SonarQube server and other is for SonarQube Database.

8. docker-compose exec: Executes a command inside a running container.
9. docker-compose run: Runs a one-off command in a new container.
10. docker-compose ps: Lists the status of all running containers.
