Failed to process input: The parameter must begin with a / or -

I am running a Dockerfile but every time it stops at one point.

RUN powershell %windir%\system32\inetsrv\appcmd.exe set config /section:system.webServer/handlers /+"[name='Test',path='Test.cgi',verb='*',modules="IsapiModule",scriptProcessor="c:\Test.dll",resourceType="Unspecified", preCondition="bitness64"]"


Failed to process input: The parameter 'verb=*' must begin with a / or -

I am struggling for hours. What could be the reason?

  • You're trying to invoke appcmd.exe via PowerShell (powershell.exe), even though the appcmd.exe command line doesn't require the features of that shell - it seems to be composed of literal strings only.

  • Your use of %windir% implies that your Dockerfile uses the default shell on Windows, namely cmd.exe

Therefore, you should be able to formulate your appcmd.exe command line as you would submit it from a cmd.exe session:

RUN %windir%\system32\inetsrv\appcmd.exe set config /section:system.webServer/handlers /+[name='Test',path='Test.cgi',verb='*',modules='IsapiModule',scriptProcessor='c:\Test.dll',resourceType='Unspecified',preCondition='bitness64']

Note:

  • All quoting in the remainder of the argument that starts with /+ now uses only '...', for consistency; since no argument-internal " chars. are therefore in play, the need to escape them goes away.

  • No spaces are allowed in the remainder of the argument.

As for what you tried:

  • When you use the -Command / -c PowerShell CLI parameter (which is implied in the absence of -File), " characters to be passed through as part of the PowerShell command must be escaped as \".

  • Since your /+ argument also contains embedded " chars., as part of the argument, you would have to escape them twice, namely as `\" (sic)
