I have the following that I would like to mount on the newman image docker run -v /C:/Users/msingathi.majola/collection:/etc/postman -t postman/newman\_ubuntu1404 \run “https:/www.getpostman.com/collections/xxxxx” --environment=“Test.postman\_environment.json” -—ssl-client-cert matthew.cer --ssl-client-key matthew.key --insecure --testReportFile=“newman-report.xml” and the error I get is as follows docker: Error response from daemon: invalid mode: /etc/postman. ---

@mseerah, Hey there, You need to use `--` to separate flags being sent to the process in the container vs flags being sent to the Docker client. Something like this should work: ```auto docker run -v /C:/Users/msingathi.majola/collection:/etc/newman -t postman/newman run "https:/www.getpostman.com/collections/xxxxx" -- --environment="Test.postman_environment.json" --ssl-client-cert matthew.cer --ssl-client-key matthew.key --insecure --testReportFile="newman-report.xml" ``` Best, Kevin ---

hi @kevin.swiber this is very helpful, but once again I’m getting an error as follows **docker: Error response from daemon: invalid mode: /etc/newman.** \*\* See ‘docker run --help’.\*\* Not really sure what is the issue with this newman folder on the image, cause when I inspect it, I don’t seem to find any issues on it ---

Also, I just tried to modify my drive according to something I came across from stackoverflow as follows: ` docker run -v /c/Users/msingathi.majola/collection:/etc/newman -t postman/newman run "https:/www.getpostman.com/collections/xxx" -- --environment="Test.postman_environment.json" --ssl-client-cert matthew.cer --ssl-client-key matthew.key --insecure --testReportFile="newman-report.xml"` _error: collection could not be loaded_ - unable to read data from file “https:/www.getpostman.com/collections/xxx”\* - ENOENT: no such file or directory, open ‘https:/www.getpostman.com/collections/xxx’\* ---

You need to change `https:/` to `https://`. Best, Kevin ---

Hey @mseerah, That’s weird. Perhaps it’s a bug in newman. I would brute force the `insecure` flag by altering a variable that will impact Node.js and see if that helps. You’ll need to add `--env NODE_TLS_REJECT_UNAUTHORIZED='0'` to your `docker run` command like so: ```auto docker run --env NODE_TLS_REJECT_UNAUTHORIZED='0' -v /c/Users/msingathi.majola/collection:/etc/newman -t postman/newman run “https:/www.getpostman.com/collections/xxx” – --environment=“Test.postman_environment.json” --ssl-client-cert matthew.cer --ssl-client-key matthew.key --insecure --testReportFile=“newman-report.xml” ``` Best, Kevin ---
