Use FUSE in local Containers development

ContainersCloudflare · Developer platform

Miniflare now automatically grants local Containers the Docker privileges required for Filesystem in Userspace (FUSE). This applies to wrangler dev, the Cloudflare Vite plugin, and direct Miniflare use.

Miniflare grants these privileges when the local Docker daemon runs inside a virtual machine (VM). This includes Docker engines on macOS and through Windows Subsystem for Linux (WSL). On Linux, Miniflare grants the privileges for local rootless Docker when /dev/fuse is available.

Rootful Docker on Linux does not support FUSE by default during local development. Miniflare does not grant FUSE privileges when the Docker daemon does not meet these conditions or cannot be inspected.

For requirements and troubleshooting, refer to FUSE support during local development. For a complete example, refer to Mount R2 buckets with FUSE.

  1. New scheduling policy for Containers to configure image and instance from Durable Objects

    Containers now support the durable_object scheduling policy in public beta. This policy lets a Durable Object select the image and instance size for a Container at runtime instead of using one centrally managed configuration for the application.

  2. Snapshot and restore Container filesystem

    Containers now support snapshot APIs in public beta for saving and restoring point-in-time filesystem state. Create a snapshot first, then pass it back to start() to restore files after container sleep, restart, or handoff to another Durable Object.

  3. Custom Container instance types no longer have a disk to memory ratio limit

    Containers custom instance types no longer limit disk based on memory. Previously, a custom instance type could have a maximum of 2 GB of disk for each 1 GiB of memory. You can now allocate up to the 20 GB disk maximum to any custom instance type.

  5. Configure observability per container application

    You can now configure observability for each container application when you deploy Containers with Wrangler. This lets you change logging for one container without changing the rest of your Worker.
