I've been trying to learn how to run some docker-dependent scripts in Mathematica.

Every time I try to run the script, I get the same error:

RunProcess::pnfd: Program docker not found.  Check Environment["PATH"].

When troubleshooting, I tried the simpler command

RunProcess[{"docker", "version"}]

which, using cmd, should yield a "valid" answer. However, I just get the same error. What am I doing wrong?

    $\begingroup$ Does RunProcess[{"docker.exe", "version"}] work for you? RunProcess will search the path but it does not default the extension. $\endgroup$

  • $\begingroup$ @WReach This most definitely works. I feel stupid for not testing that first, damm. Thank you kindly! $\endgroup$

Thanks to @WReach, a solution has been found. Apparently, all that it takes is to specify the windows extension, ".exe". As such, his command


yields the expected result
