CRFS is a read-only FUSE filesystem that mounts container images directly from a container registry without pulling them locally first. It introduces the Stargz (seekable tar.gz) format, which indexes gzip streams so individual files can be read on demand over the network.

Use cases

  • mount container images from a registry without pulling them
  • speed up container startup on cold nodes
  • read individual files from a remote container image lazily
  • avoid pre-pulling large containers in CI build VMs
  • convert tar.gz images to the seekable Stargz format

When to choose

  • container image pull time dominates startup latency
  • you want on-demand reads of image layers over a fast internal network
  • you can build images in the Stargz format and mount them on Linux with FUSE

When to avoid

  • you need a writable container filesystem
  • you're not on Linux or lack FUSE support
  • you need broad ecosystem support - the project is in maintenance mode and alternatives like containerd stargz-snapshotter are more active
