claude-hdb
0c9971ecf8
A CLI that mints trust-less, network-isolated Incus VMs with Claude Code installed. Boxes are strictly creds-free — the operator logs into Claude interactively inside; authenticated state is reused via snapshots. The tool knows nothing about projects; a repo ships an optional agent-facing .claudebox/ runbook that Claude reads. - bin/claudebox: new/shell/exec/snapshot/restore/down/start/rm/status; creds-free 'new' (fresh launch or clone via --from <src>[/<snap>]). - cloud-init: global ~/.claude/CLAUDE.md self-describing the box + .claudebox/ runbook. - install.sh: curl-pipe-bash installer. - host/: Incus isolation stack (claudenet + claude-isolate ACL + claude-dev profile + firewall). - docs/: design + .claudebox/ convention. Initial canonical import (prototyped separately; re-homed onto the heavy-duty fork). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# --- Firewall coexistence ---------------------------------------------------
|

# Hosts running UFW (INPUT drop) and/or Docker (FORWARD drop) silently eat
|
|
# claudenet traffic. Punch minimal, ordered holes; the Incus ACL still layers
|
|
# on top. The trailing deny also blocks instance -> host's own (public) IPs,
|
|
# which the RFC1918-only ACL cannot express. Rules live in
|
|
# claudebox-firewall.sh; a boot-time systemd unit re-applies the runtime-only
|
|
# parts (nft table, DOCKER-USER) after every reboot.
