Description John Fulton 2020-07-01 18:32:22 UTC 
Our current deployment has glance-direct enabled [1]

However, because our standard procedure doesn't include the shared file system on the controller nodes, we should disable it by default for DCN deployments.

If the image is on a web server the `glance image-create-via-import` command, which automatically converts the QCOW2 image to RAW format, works with the ‘web-download’ method. It will continue to work if glance-direct is disabled.

Since our documentation [2] already states that there's a common filesystem requirement for 'glance-direct', that it's a bug that we enable it.

[root central-controller0-2 ~]# podman exec glance_api cat
/etc/glance/glance-api.conf | grep -v \# | grep direct
show_image_direct_url=True
enabled_import_methods=[glance-direct,web-download,copy-image]
[root central-controller0-2 ~]#
