How does Wave / Fusion2 work with Singularity?

[gwright99]

NGC is interested in leveraging Fusion2 via Wave. Their compute is an on-prem HPC which must run all containers as Singularity images. They have asked how/if Docker images pulled from via Wave are converted to Singularity images.

Questions:

1. Do we have existing content explaining this flow? If not:
   1. Can I please get of explanation of what is / is not possible?
   2. If possible, can someone from the Wave/Nextflow team please outline what this sequence flow looks like?

Let's start the "Discussion" section in Wave! 😄
