portal.sagecontinuum.org maintains a catalog of edge deployable applications for their smarter-cities project
portainer.io maintains git repositories of templates which are then deployable using their portainer.io tool (including the community edition)
Requirements
For helm appropriate projects (those that use kubernetes as a base layer)
helm-ifying (as necessary) template components
umbrella helm which deploys those components
role-designation methodology for multi-node blueprints (or even to specify cloud-side versus edge-side)
host on a catalog platform
For other projects
TBD - options include using things like portainer.io or just docker-compose, but unaware of a artifacthub.io equivalent for those so maybe just github/gitlab?
