I really like Paas: Heroku, Openshift and the new Docker, but currently I can't access anymore via ssh to a remote app on Openshift.
$ rhc ssh -a testrb ⬆ ◼
Connecting to firstname.lastname@example.org ...
Traceback (most recent call last):
File "/usr/bin/oo-trap-user", line 266, in <module>
os.execv(cmd, [cmd] + allargs)
OSError: [Errno 7] Argument list too long
Connection to testrb-grigio.rhcloud.com closed.
Unfortunatly the only way to access again seems to be the human intervetion from a Redhat guy, but fortunatly it was a test app and not real production data was involved.
