Unable to find image '/dev/null:/portforward:ro' locally

Hi, when I run dockersh I get this error:

could not start container: exit status 1:
Unable to find image '/dev/null:/portforward:ro' locally
2014/10/09 13:50:25 Invalid namespace name (), only [a-z0-9_] are allowed, size between 4 and 30

I'm running Ubuntu 14.04.1 LTS with:

Client version: 1.2.0
Client API version: 1.14
Go version (client): go1.3.1
Git commit (client): fa7b24f
OS/Arch (client): linux/amd64
Server version: 1.2.0
Server API version: 1.14
Go version (server): go1.3.1
Git commit (server): fa7b24f

Just installed dockersh from dockerhub.

Hi, I just tried the latest version and now I'm getting this:

$ ssh myuser@myhost
Error starting shell in new container: Cannot find your shell /bin/bash inside your container
Connection to myhost closed.

This is my /etc/dockersh:

[dockersh]
imagename = ubuntu:trusty
shell = /bin/bash
mounthome

If I use your example with busybox and ash, it works. Do the images need something special configured? How isn't /bin/bash found in ubuntu:trusty? It is there.

Thanks.

Is your container already running? I.e. if you start a persistent container with busybox, and then change the config to ubuntu:trusty?

dockersh won't automatically recycle the container for you - you'll need to manually docker kill youruser_dockersh ; docker rm youruser_dockersh to get a new container with the new OS started

Oh, maybe that's what happened. I just tried with no running containers and it worked. Thanks!
