docker : commit doesn't seem to persist changes by the passwd command
docker run -i -t dhrp/sshd /bin/bash root@f123d1d12d>passwd ...change the pw In another shell : docker commit f123d1d12d max/sshd fbf0b19e284f max@max-ubuntu:~$ docker images max/sshd latest fbf0b19e284f 13 seconds ago 21.12 kB Then I start the container : docker run -d -p 22 max/sshd /usr/sbin/sshd -D docker ps ID IMAGE COMMAND CREATED STATUS PORTS 440871de534f dhrp/sshd:latest /bin/bash 34 seconds ago Up 34 seconds 49164->22 then I try to login : root@localhost 49164 using the password "commited" earlyer, and it fails (invalid passwd or username).... To make sure the commit is done properly I did : echo 123 > test inside the container before the commit and then run >docker run max/sshd cat test >123 so the commit is doing something, just not persisting the passwd command... Versions : max@max-ubuntu:~$ docker version Client version: 0.5.0 Server version: 0.5.0 Go version: go1.1 and dhrp/sshd is whatever happens to be in the docker index....

Ok, here’s what the problem was :
Not invoking the ssh client properly :
should have been :
root@localhost -p 49164
I’ll close the question because it will just add noise….
