I ran this, and Git now works as expected, and changes should now be present in OpenShift builds.

@jonespm and I talked about trying to remove git as a dependency in the running container, but it proved more challenging than expected (it's hard to set environment variables with command output in a Dockerfile). We could look into this at a later date.

Filed the git removal as an issue on #1462 and worked on a draft PR for it. Thanks for the review!
