FUSEd with nix: deploying nix apps to k8s in images weighting as little as 500 KBs
2024-10-26 , Arena

Deploying nix-built applications to a Kubernetes cluster can be an exercise in frustration - even though nix has built-in support for creation of container images, the outcome is usually a quite sizable tar archive. Propagation, caching and updating of such images takes time, bandwidth and storage space. One is essentially packaging little slices of a nix store, every time an application needs to be delivered. There has to be a better way!

We want to present a FUSE-based way of attaching a shared /nix/store to container images and thus allowing them to only contain metainformation required to run the application. Even complex k8s deployments are reduced to very thin updates of data!
