1 DLaaS deployment at DESY

Muhammad Aleem Sarwar, along with his colleagues at DESY in Hamburg, will present the implementation of the DESY Rucio instance and its DLaaS ongoing development.

Discussion:

• The only problem of the DESY DLaaS is the OIDC authentication as it needs to go through the ESCAPE IAM
• A couple of things changed in th datalake singleuser Docker image for DESY wrt ESCAPE one:
  • configure_jupyter scripts
  • DESTINATION_RSE is DESY-DCACHE
  • RUCIO_CONFIG had to be slightly changed to adapt to the linux user id specific to dcache
  • permissions on config files
• Paul Millar: Could we edit the Docker file to be more universal and adapt to everyone's needs so that only some env variables need to be changed? Martin Barisits: yes we can accept some pull requests but in the long run we should identify someone taking care of this.
• The authentication is done through X509 as a rucio client, if this happens anyone can access the ESCAPE Rucio services
• Not any short temr plans to run heavy workloads there, rather connect to external batch system/slurm
