# It's important that we don't explicitly pull this image here.  Otherwise we
# could result in upgrading a preinstalled environment.  We'll have to set
# openshift_image_tag correctly for upgrades.

# Determine openshift_version if none is set for this host, or if a generic "3.2"
# is set, determine the more specific version number by either installing the latest
# rpm, or pulling the v3.2 container and checking the resulting versions.
