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.

Additional guidance for making buckets public

• Web client
• Swift client
• S3 client
• a-commands
