Description of problem:

When trying to build a Docker images using the 'busybox' base image, the user may receive an error like "image ID '' is invalid".


Version-Release number of selected component (if applicable):

docker-1.8.2-10.el7.x86_64


How reproducible:

Sporadic.


Steps to Reproduce:
1.  Create Dockerfile that contains 'FROM busybox'
2.  docker build -t <name> <path/to/Dockerfile>


Actual results:

-bash-4.2# docker build -t busybox_httpd /root/busybox_httpd/
Sending build context to Docker daemon 2.048 kB
Step 0 : FROM busybox
image ID '' is invalid


Expected results:

-bash-4.2# docker build -t busybox_httpd /root/busybox_httpd/
Sending build context to Docker daemon 2.048 kB
Step 0 : FROM busybox

Additional info:

I've observed this sporadically while testing on RHELAH.  Unfortunately, I have not been able to reliably reproduce this.

I have an Ansible playbook that attempts to build and run Docker images using a number of base images.  In the most recent attempt to run the playbook, the first image build/run was successful using the 'alpine' base image. However, the follow on build/run of 'busybox' failed.

Below are some details from the system where I last saw the issue.
