Sadly like many Docker Swarm based projects, this has become abandonware. I use Docker Swarm with Portainer for managing services with ecoeats[1], a decision that was made years ago, just before Swarm was revealed to be absolutely dead in the water. I initially used Swarmlet before switching to Portainer, as there were far too many bugs and missing tools needed to effectively manage a Swarm that went beyond stateless Node containers.
With Portainer and Swarm I've been forced to manually intervene with rollouts more times than I would have liked due to Swarm-specific errors and other quirky networking behaviour. At least it's simpler than Kubernetes!
I'm building a webapp[0] for turning Clickup docs into static sites, using CF Workers. There isn't a framework for Workers that has the flexibility I need, so I home-rolled one that only sends rendered HTML over the wire. Async components are supported too, so if I have a particularly data-intensive component the renderer just inlines a tiny JS script that sends a request to the worker again, which then returns just that component in HTML.
Could be worth releasing on its own as a GitHub project!
