Updating container images.

The container images used at the FRIB have their descriptions held in

https://git.nscl.msu.edu/daqdev/nscldaq-containers

Only the appropriate FRIB people (with push access to that repository) can change these images. To update the images:

• Clone the repository.
• Make whatever changes are needed to the container builds for Docker.
• Commit and push to the repository.

gitlab will then:

• Automatically create the images and publish them to hub.docker.com
• Pull the new image(s) to /scratch on our dev system.

From there they can be deployed or otherwise moved into place.
