docker-volume-hetzner VS nixery

we use https://github.com/costela/docker-volume-hetzner which is really stable.

CSI support for Swarm is in beta as well and already merged in the Hetzner CSI driver (https://github.com/hetznercloud/csi-driver/tree/main/deploy/...). There are some rough edges atm with Docker + CSI so I would stick with docker-volume-hetzner for now for prod usage.

Disclaimer: I contributed to both repos.

The big one which would be nice: CSI support. This is currently being worked on, though. This said the current volume plugin landscape is not that dire once you realize that the local volume driver which arguably has a confusing name can work with NFS,CIFS,etc. out of the box as long as you can use fuse mounts. Besides that, we are quite happy with our setup where we use the community volume driver for our cloud provider - https://github.com/costela/docker-volume-hetzner/

Reasons that we would dabble in k8s again:

1. A lot of projects are k8s only (see OpenFaaS for example)

The ones from https://nixery.dev/

You can build your own with https://nixery.dev/

I built a service for doing this ad-hoc via image names a few years ago and it enjoys some popularity with CI & debugging use-cases: https://nixery.dev/

name is eerily similar to `nixpkgs`, i.e. the monorepo that defines all packages and one of the underlying technologies here. i get the play on buildpacks, but still, as a nix user it makes me do a double take reading the name

this is neat though, and in political terms, the elevator pitch mentions nix itself as an implementation detail in passing. hopefully, if this catches on, it'll function as a non-threatening gateway drug to nix itself, when users inevitably go digging into the weeds

for anyone interested, prior art on the nix container front: https://nixery.dev

Wow, this is excellent! At a previous job, we had been using k8s + knative to spin up containers on demand, and likewise were unhappy with the delays. Spawner seems excellent.

One question: have you had to do any custom container builds on demand, and if so, have you had to deal with large containers (e.g. a Python base image with a few larger packages installed from PyPI)? We would run up against extremely long build image times using tools like kaniko, and caching would typically have only a limited benefit.

I was experimenting using Nix to maybe solve some of these problems, but never got far enough to run a speed test, and then left the job before finishing. But it seems to me some sort of algorithm like Nixery uses (https://nixery.dev) to generate cacheable layers with completely repeatable builds and nothing extraneous would help.

Maybe that's not a problem you had to solve, but if it is, I'd love your thoughts.
