Meeting dedicated to ARC image for deployment in a container.

The proposed solution is OK, but there are some practical concerns of its usfulness. One concern is that ARC-CE is a stateful service, so needs some persistent storage and can not be migrated effortlessly. Another is that it needs to be interfaced to a specific batch system (e.g. SLURM) which itself is not trivial to containerise. In the end of the day, each deployment needs lots of tailoring, which reduces benefits of containerisation. DTR can be containerised as a standalone service, if transfer jobs are implemented: cloud storage costs a lot, so cache is not attractive for cloud-based deployments.
