As a newcomer,

I installed docker Desktop for Windows.

Following https://testcontainers.com/guides/getting-started-with-testcontainers-for-java/ got error:

Following the on failure link has not helped a lot.

There must be missing some trivial assumption. If I start PowerShell I get:

PS C:\Users\ppku> docker --version
Docker version 24.0.6, build ed223bc

so docker is on path.

Quite not understand why probing failed.
Could you investigate, pls?

Relevant log output

Inizia con la guida getting-started-with-testcontainers-for-java e con la documentazione on_failure collegata, quindi riproduci la configurazione di Windows Docker Desktop usando i logs riportati. Analizza il motivo per cui l’esempio non riesce a trovare un ambiente Docker valido; il lavoro è completato quando l’esempio newcomer viene eseguito correttamente oppure quando la guida documenta chiaramente il prerequisito mancante e il passaggio di troubleshooting.
