We are using Juno version of Openstack and wanted to see if there is an option in restricting tenants from uploading the images in horizon. We dont want other uses to upload the image and mess up our environment. Any help would be appreciated !

thanks, Aravinda

Every service has policy.json which defines policies for accessing API. If you don't want others to upload the images than you can allow only admin to upload images by modifying the /etc/glance/policy.json file such that users having admin role only they can use add_image api. So this way you can restrict users other than admin to upload images.

Usually at the beginning of the file they define an entry that corresponds to admin role. In OpenStack documentation(, it is "context_is_admin" therefor you can replace the entry having add_image API with "add_image": "rule:context_is_admin".

Thanks for the details Rajiv. I did change this in jason but unfortunately its not working. Is there any service that need to be restarted ? here is the excerpt of the jason file "context_is_admin": "role:admin", "default": "", "add_image": "role:admin", "delete_image": "role:admin"

Let's assume you made this change so only admins could upload images. Would this affect non-admin users' ability to take snapshots?
