Is it possible to make data in Allas read-only?
Inside a project
Inside a project there is currently no read-only mode in Allas. Each project member has full access to the data, which causes a risk: any project member can accidentally overwrite or delete data.
Between projects
You can give another project read-only access to your bucket using Swift or S3cmd.
Sharing URL
In addition, it is possible to make a bucket public, which makes the content
available for viewing ("read-only") via URLs. The URL to an object in a
public bucket is of the form https://<bucket_name>.a3s.fi/<object_name> or
https://a3s.fi/swift/v1/AUTH_<project_id>/<bucket_name>/<object_name> where
<project_id> is the identifier of your computing project in
UUID
format.
