Thanks for sharing this! The initial problem outlined is a general one when dealing with monorepos. Tools like pantsbuild.org do a great job of solving this for you in general which as you've found is really tricky. I think it would be a great fit to add a plugin for Pants for running Dagger tasks.

Do you think that the flow should be from pants to run dagger pipelines or the dagger pipelines run pants ?

@warm parcel , do you still think this is a good idea? I'm well acquainted with the Pantsbuild maintainer and I can ask him to help me do this.

Well, Pants has this thing called goals which allows you to add plugins, so maybe the thing to do would be to create a pants dagger goal and then run the dagger code in the project so that the developers can use their SDK of choice.

Not sure. I ended up not adopting dagger as I couldn't really wrap my head around how I could get a local version of CI. I ended up using kubernetes + helper tools for portable CI. In this case it doesn't really interact with pants at all.

I think the benefit would be to use pants to figure out what does/doesn't need run and inject those into the CI task. Dagger in pants or pants in dagger, I'm not sure.
