i am trying to create a nanoserver-iis-php8 docker image. when copying the instructions in php site to a docker file like this line RUN powershell -command c:\windows\system32\inetsrv\appcmd set config /section:system.webServer/fastCGI /+[fullPath='c:\php\php-cgi.exe'] i get this error message when building the image:
ERROR ( message:Malformed collection indexer; format is [@position,name='value',name2='value2',...]. The @position specifier is optional, and be '@start', '@end', or '@N' where N is a numeric index into the collection. )
how do i fix this?
