I would really love to hear more about this, but my cursory search didn't find a write up about it.

I did a PoC of Dagger for an integration and delivery workload and loved the local development experience. Being able to define complex pipelines as a series of composable actions in a language which can be type checked was a great experience, and assembling these into unix-style pipelines felt very natural.

I struggled to go beyond this and into an integration environment, though. Dagger's current caching implementation is very much built around there being a single long-lived node and doesn't scale out well, at least without the undocumented experimental OCI caching implementation. Are you able to share any details on how Fastly operates Dagger?

We don't have any public posts around our setup (yet), but I think it's time we do. I'll put some time into it and will revert here to link to it.
