I’d love to hear more about some limitations/tradeoffs of docker that you made at the time that you regret in hindsight. Was there anything that you wish didn’t get baked into the “default norms” for containers, or areas that would benefit from more attention and redesigns?

I’ve been following dagger and it’s been really interesting to see the evolution of the design, and new set of abstractions. There’s also nix which has seen popularity, with their approach of building layered oci containers.
