Powershell Variables unable to use with --link $VARIABLE:<name>


(Solidstrider) #1

Expected behavior

$WEB_CID = docker run -d nginx
docker run -d --link $WEB_CID:insideweb dockerinaction/ch2_agent

In Poweshell, Docker for Windows should work with the $WEB_CID variables for the actual CIDs for the --link

Actual behavior

PS C:\Users\tonyh\OneDrive\Work\2015-05-05-Docker> docker rm -vf (docker ps -a -q)

Steps to reproduce the behavior

  1. Execute: $WEB_CID = docker run -d nginx
  2. Execute: docker run -d --link $WEB_CID:insideweb dockerinaction/ch2_agent
  3. Get error.

@solidstrider I think you need to escape the colon (with a backtick). This works for me:

$WEB_CID = docker run -d nginx
docker run -d --link $WEB_CID`:nginx debian

(Solidstrider) #3

Great! That backtick did the trick!! Thank you Friism!
