# Container image for the container example.
#
# Pulls the computerd binary out of the public GHCR image. That image is
# a single layer over `scratch` whose only contents are the SEA
# binary at /usr/local/bin/computerd; we COPY it into a slim debian
# runtime below. The :VERSION tag is rewritten by the changesets
# Version Packages PR through .github/changeset-version.mjs.
#
# computerd mounts a FUSE filesystem at MOUNT_POINT so exec'd commands
# see the same VFS the RPC surface reads and writes. With
# FUSE_MOUNT=auto (below) the same image works in both directions:
# Cloudflare Containers expose /dev/fuse to the workload, so the
# real FUSE backend mounts; `wrangler dev` doesn't, so computerd falls
# back to the userspace shim transparently.
