On: Show HN: Nix Snapshotter – Native understanding of...

[alex_hirner]

I think your usage example will be easier to understand, if it explains where nix:0 is setup as CRI image-service. Maybe I glanced over it.

Awesome project!

Hi Alex, I’ve updated the README with a bit more information.

0 is actually an unbindable port, so nix:0 is just an arbitrary string that is unlikely to have conflicts. The Kubelet needs to be configured with —image-service-endpoint to use the nix-snapshotter gRPC socket to handle the “PullImage” RPC. There we can take over resolving the image reference when it’s prefixed with nix:0.
