APPLICATION FAILED TO START
***************************

Description:

Could not find a valid Docker environment for Testcontainers.

Action:

    - Ensure a Docker-compatible container engine is installed and running.
    - If running Testcontainers in CI, ensure the runner has access to the daemon, typically by using a mounted socket or a Docker-in-Docker setup.
    - Review the Testcontainers documentation for troubleshooting and advanced configuration options.
