Docker:"invalid reference format" in Powershell

Question

I have pulled a node js image from the docker hub and with node express generator I generated a little sample site.
I want to create a volume inside a Docker container and map the site folder with that volume.

I want to run the node from the docker container.
I am using this command:

docker run -p 8003:3000 -v $(pwd):/var/www -w "/var/www" node npm start

Could anyone please help me out?

Which of the two suggestions was it in your case? – VonC Jun 15 '19 at 05:21 — VonC, Jun 15 '19 at 05:21

First, check if you have typed or copy-pasted the docker run command.
In the later case, re-type the '-' (dash) manually in order to avoid using by mistake a minus

 docker run -p 8003:3000 -v
           ^^^          ^^^
 type manually *all* those '-'

Second, check if the $(pwd) should be, in a Powershell session, -v ${PWD} instead.
