Getting Error

[MTRNord]

When I run
./docker-stfd mtrnord/projectstreet_detection:latest sh -c "PYTHONPATH='/usr/lib/python2.7/dist-packages/' python face_detect.py abba.png haarcascade_frontalface_default.xml >> /root/shared/results/logs.txt"

I get

Reverse engineering Dockerfile...
Traceback (most recent call last):
  File "./docker-stfd", line 73, in <module>
    baseimage = next(l for l in dockerfile if l.startswith('FROM')).split()[1]
StopIteration

I run that inside an docker container (if that makes any difference)

Pulled your image and I'm able to reproduce this. What version of Docker are you using? Also, what does docker history mtrnord/projectstreet_detection show?

Ok, all those <missing> I think means that you didn't build the image on the same system as you are trying to run stfd on it, is that correct? If so, can you try building the image locally then running stfd?

It may be necessary to have the build cache present for stfd to work and as of Docker 1.10 this doesn't get pulled anymore if you built the image on a different system (see also moby/moby#20316)

[MTRNord]

I will try that :) I did let it build on the dockerHub build system

[marius311]

Cool, if it fixes it let me know. I should add a big warning to the README.

[MTRNord]

Ok now I get some errors that are coming from centurylink/dockerfile-from-image (this one: CenturyLinkLabs/dockerfile-from-image#14 ) And also the fix there generates a new error :& But I think I should post that error in the issue tracker for centurylink/dockerfile-from-image

[marius311]

Ah yea, I was getting that too. The solution mentioned there worked for me. Either rebuild the CentryLinkLabs/dockerfile-from-image image yourself, or switch stfd to use dduvnjak/dockerfile-from-image instead here https://github.com/marius311/stfd/blob/master/docker-stfd#L70

[MTRNord]

Ok rebuilding only got me to another error. But I will try the other image :)

[MTRNord]

Both solutions give me than:

/usr/src/app/dockerfile-from-image.rb:33:in `block in <main>': undefined method `first' for nil:NilClass (NoMethodError)
    from /usr/src/app/dockerfile-from-image.rb:32:in `each'
    from /usr/src/app/dockerfile-from-image.rb:32:in `each_with_object'
    from /usr/src/app/dockerfile-from-image.rb:32:in `<main>'

[marius311]

Hm odd, I'm not sure the issue. If you share the Dockerfile I could try building the image myself and debugging further.
