Implement the host agent as a Connect RPC server that orchestrates sandbox creation, destruction, pause/resume, and command execution. Includes sandbox manager with TTL-based reaper, network slot allocator, rootfs cloning, hostagent proto definition with generated stubs, and test/debug scripts. Fix Firecracker process lifetime bug where VM was tied to HTTP request context instead of background context.

# update-debug-rootfs.sh — Build envd and inject it (plus wrenn-init) into the debug rootfs.
|
|
#
|
|
# This script:
|
|
# 1. Builds a fresh envd static binary via make
|
|
# 2. Mounts the rootfs image
|
|
# 3. Copies envd and wrenn-init into the image
|
|
# 4. Unmounts cleanly
|
|
#
|
|
# Usage:
|
|
# bash scripts/update-debug-rootfs.sh [rootfs_path]
|
|
#
|
|
# Defaults to /var/lib/wrenn/images/minimal.ext4
