Test kitchen + ntp cookbook + docker?


So after upgrading to chefdk 0.5.0rc5, I’ve been able to get past the
issues I had and now I can run kitchen converge on the ntp cookbook and it
connects to docker and seems to work great.

Except that it never actually completes, it’s hanging on this output:

   -# Local users may interrogate the ntp server more closely.
   -restrict ::1

   -# Clients from this (example!) subnet have unlimited access, but

only if
-# cryptographically authenticated.
-#restrict mask notrust
-# If you want to provide time to your local subnet, change the
next line.
-# (Again, the address is an example only.)
-# If you want to listen to time broadcasts on your local
subnet, de-comment the
-# next lines. Please do this only if you trust everybody on the
-#disable auth
* execute[Stop ntp in preparation for ntpdate] action run
- execute /bin/true
* service[ntp] action stop (up to date)

Checking docker ps doesn’t show much helpful:

ashdcsbamboo00:~ docker -H tcp://localhost:5000 ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ffc2cb76a630 24b877679eab "/usr/sbin/sshd -D - 9 days ago Up 9 days>22/tcp reverent_feynman ashdcsbamboo00:~

Nor does a ps inside the container:

root@37968806dcbf:/tmp/kitchen# ps aw
91 pts/0 Ss+ 0:00 sh -c sudo -E /opt/chef/bin/chef-solo --config
/tmp/kitchen/solo.rb --log_level auto --force-formatter --no-color

427 pts/0 S 0:00 ntpd -q
430 ? S 0:00 bash
460 ? R+ 0:00 ps aw

After manually killing the ntpd proccess (service ntpd stop did not work
for some reason), as the last thing chef-solo showed was an attempt to stop
the ntpd service, I got a bit further:

     * execute[Force sync system clock with ntp server] action run
   - execute ntpd -q
     * execute[Force sync hardware clock with system clock] action run

Error executing action run on resource ‘execute[Force sync
hardware clock with system clock]’


       Expected process to exit with [0], but received '70'
       ---- Begin output of hwclock --systohc ----
   STDERR: hwclock: Cannot access the Hardware Clock via any known

hwclock: Use the --debug option to see the details of our search
for an access method.
---- End output of hwclock --systohc ----
Ran hwclock --systohc returned 70

Is this a known issue with docker containers and the hardware clock?
Running the command directly with --debug shows:

root@37968806dcbf:/tmp/kitchen# hwclock --systohc --debug
hwclock from util-linux 2.20.1
hwclock: Open of /dev/rtc failed: No such file or directory
No usable clock interface found.
hwclock: Cannot access the Hardware Clock via any known method.

I’m basically using the ntp cookbook tests to verify that I have my TK +
docker setup correct, so that I can then move on to writing my own tests,
so if this is just a specific issue with this cookbook, then I can move on.
Just not sure if there are any other gotchas I need to look out for.
