Issue

Following this documentation regarding using FUSE as FS with R2 in Cloudflare Containers, i encountered the following bug:

• Possible to enable FUSE? containers#112 (comment)

I figured out, there is no option for the end user to enable/ask workerd to run Docker in privileged mode for local testing which hinders local testing of containers for certain applications. (Eg: FUSE support/modprobe)

Proposed Solution

• Expose runPrevileged option and append it:
  

  workerd/src/workerd/server/container-client.c++

  Line 287 in 4d3bfd7

  auto hostConfig = jsonRoot.initHostConfig();

  
  if enabled, the docker api capnp already has the specs
  

  workerd/src/workerd/server/docker-api.capnp

  Line 145 in 4d3bfd7

  privileged @30 :Bool $Json.name("Privileged");

• Generate Capnp and allow Miniflare to access this for local-development

• Miniflare exposes this as a config to wrangler

• User can set a wrangler config either via config file or via CLI params wrangler dev --previleged

Would like to know your thoughts on this, and would love to contribute regarding the same!
