You don't need docker at all for this. Dagger supports nesting as a native feature

Oooh!

Just set the ExperimentalPrivilegedNesting option in WithExec, and that command can magically make dagger API calls in the correct (nested) context

#

This works at arbitrary depth, too. So you can have dagger-in-dagger-in-dagger, etc

That's pretty awesome, definitely solves the horrid dind problems I've faced in the past. At least at the dagger level 😉

yeah, one benefit of having built Docker is that we know exactly where the most painful problems are, and we get to go back in time and fix it early 🙂

here's an example Adrian https://twitter.com/solomonstre/status/1605766970816823296

Some of you will appreciate this. It sure blew my mind..

When @dagger_io runs a container, that container now has full Dagger API access. It can then run more containers, and so on AT ARBITRARY DEPTH.

Infinite Dagger in Dagger 🤯

Lmao, this is awesome. Thank you for the example, I got it working for my node tests and it works flawlessly on the first try! 🤯

we test dagger-in-dagger in our CI as a sanity check for other tests we run on top of it, here's a couple more examples

@royal juniper That's awesome, love the gha in cue. The gha yaml is so impossible.
