Inception
When you wake up, you will believe.
What?
It runs a container nested to an arbitrary depth.
How?
Recursion.
Set DINCEPTION\_DEPTH to the nesting level you want.
Like this:
$ DINCEPTION_DEPTH=0 ./dinception run --rm -ti busybox echo hi
hi
$ DINCEPTION_DEPTH=1 ./dinception run --rm -ti busybox echo hi

hi
Why?
Because it's Friday.
Also, on the off chance someone breaks out of a container, they will just be in another container. So they'll break out again. And then they'll be in another container.
But mostly because it's Friday and doing crazy things with Docker is more fun on Friday.
Opportunities for Improvement
It'd be nice not to have to pull containers at every level.
I think I'd need kojiromike/dind to contain itself, which
is hard.
Right now you have to use my dind.
