Optmizing availability

[jonathanbeber]

I'm trying to understand whether optmizing is possible with any other tool but ctr-remote.

Curently I'm using buildKit and it works great, but I just realised that with ctr-remote I could cut in at least half the startup time of my pods. On my tests, the latency of creating a pod and accessing its HTTP API goes from 13 seconds without optimization (simply docker buildx) to 3 seconds (with ctr-remote).

I'm using pods on my CI, what makes DinD already kind of challenging and running containerd I believe will be another kind of difficult setup, so, if possible, I would like to understand if buildKit, nerdctl or Kaniko can run any kind of optimization too.

If not, is any work in this direction on going?

Thanks in advance.
