# Air-gap Egress Guard Rails

Artifacts supporting `DEVOPS-AIRGAP-56-001`:

- `k8s-deny-egress.yaml` — NetworkPolicy template that denies all egress for pods labeled `sealed=true`, except optional in-cluster DNS when enabled.
- `compose-egress-guard.sh` — Idempotent iptables guard for Docker/compose using the `DOCKER-USER` chain to drop all outbound traffic from a compose project network while allowing loopback and RFC1918 intra-cluster ranges.
- `verify-egress-block.sh` — Verification harness that runs curl probes from Docker or Kubernetes and reports JSON results; exits non-zero if any target is reachable.
- `bundle_stage_import.py` — Deterministic bundle staging helper: validates sha256 manifest, copies bundles to staging dir as `<sha256>-<basename>`, emits `staging-report.json` for evidence.
- `stage-bundle.sh` — Thin wrapper around `bundle_stage_import.py` with positional args.
- `build_bootstrap_pack.py` — Builds a Bootstrap Pack from images/charts/extras listed in a JSON config, writing `bootstrap-manifest.json` + `checksums.sha256` deterministically.
- `build_bootstrap_pack.sh` — Wrapper for the bootstrap pack builder.

See also `ops/devops/sealed-mode-ci/` for the full sealed-mode compose harness and `egress_probe.py`, which this verification script wraps.
