Trying with the last version of disco (removed tag/0.5 : discodocker works fine with current repo, except little messages -> for another issue) , the test is failing, climbing back the stack of commands, i launched discobase with bash : 

# cd /disco
# bin/disco nodaemon

...

But webserver is available on port 8989 -> then stop disco and try

# ssh localhost
ssh: connect to host localhost port 22: Connection refused
# ps -aux
no sshd !

Launching sshd and everything is back to normal.

Moving to https://github.com/phusion/baseimage-docker instead of ubuntu to have a better environnement. Read http://phusion.github.io/baseimage-docker/ ;)

Still having the problem of sshd not launching .... I suspect a problem with /etc/hosts and ::1 ipv6 .... digging .... Was able to have a job launched with interactive bash after launching /usr/sbin/sshd

I've updated the image to Ubuntu 14.04 and docker 1.5.3 and it works for me. please try again.

I'm not sure what you are trying to do or what is your issue. I have no problem sshing to the master from the test image:

λ  docker run -it --link=discomaster:discomaster --volumes-from discomaster gijzelaerr/discotest /bin/bash
root@7e5aa903c49a:/# ssh discomaster

Ubuntu 14.04, Docker version 1.1.2, build d84a070, rebuild all with updated repo. Ssh working fine between test and master. Job launched -> same problem than #3

Working on this here : https://github.com/lc3t35/discophusion
