help w/ my hanging Packer docker build

[Russell Roy]

I'm trying to use packer to build a docker image via a chef-solo provisioner with a jenkins cookbook.

Here's my packer file...

{

    "builders": [{

   "type": "docker",

"image": "linux/chef-solo",

"export_path": "image.tar"

    }],

    "provisioners": [{

   "type": "chef-solo",

   "cookbook_paths": ["./chef-repo/cookbooks/"],

"run_list" : ["jenkins::master"],

"prevent_sudo" : false,

"skip_install" : false

    }]

}

 

When I run 'packer build my_packer_file.json' the silly thing just hangs on me (wait forever).   Here's the (partial) debug output:

...

If I shell into that container and run the command it seems to complete ok (below.)     Any ideas?

(PS:   On another point though...  I don't understand why it wants to try to install chef-solo to begin with when I'm starting w/ a docker linux(ubuntu)/chef-solo image.)

My original posting was somewhat in error:  as originally shown, when my build hung, from a separate terminal window I'd attached to a what I thought was the correct running container (but as you can see from my log output I'd actually run a *new* container.)    I've since recreated the problem scenario, attached to the correct running container in which the running build is hung, and looked to see that the temp file the build is waiting on does in fact exist: /packer-files/cmd870430499-exit with contents "0".

So ... I suspect a bug in the packer-builder-docker module whereby somehow it's not waking up when this file comes into existence.
