Serve daemon-managed .vm names directly from bangerd on 127.0.0.1:42069 instead of shelling out to mapdns. This keeps DNS state tied to VM lifecycle and lets the daemon rebuild records from running VMs after startup or reconcile. Add a small in-process authoritative DNS server, register and remove records from the VM start/stop/delete paths, and show the listener in daemon status. Remove the mapdns config and preflight surface, stop helper-flow DNS publishing in customize.sh and interactive.sh, drop dns.sh from the runtime bundle, and update docs/tests for the new local-resolver integration model. Validated with GOCACHE=/tmp/banger-gocache go test ./..., GOCACHE=/tmp/banger-gocache make build, and bash -n customize.sh interactive.sh.

# Repository Guidelines
|
|
|
|
## Project Structure & Module Organization
|
|
- `cmd/banger` and `cmd/bangerd` are the primary user-facing entrypoints.
|
|
- `internal/` contains the daemon, CLI, RPC, storage, Firecracker, and system integration code.
|
|
- `customize.sh`, `make-rootfs.sh`, and `interactive.sh` remain as image-build/customization helpers; normal VM lifecycle, NAT, and `.vm` DNS are handled by the Go control plane.
|
|
- Source checkouts use a generated `./runtime/` bundle for Firecracker, kernels, modules, rootfs images, and helper copies. Bundle defaults come from `./runtime/bundle.json` when present. Those runtime artifacts are not meant to be tracked directly in Git.
|
|
- The daemon keeps state under XDG directories rather than the old repo-local `state/` layout.
|
|
|
|
## Build, Test, and Development Commands
|
|
- `make build` builds `./banger` and `./bangerd`.
|
|
- `make runtime-bundle` bootstraps `./runtime/` from the archive referenced by `RUNTIME_MANIFEST`; the checked-in `runtime-bundle.toml` is only a template.
|
|
- `banger` validates required host tools per command and reports actionable missing-tool errors; do not assume one workstation's package set.
|
|
- `./banger vm create --name testbox` creates and starts a VM.
|
|
- `./banger vm ssh testbox` connects to a running guest.
|
|
- `./banger vm stop testbox` stops a VM while preserving its disks.
|
|
- `./banger tui` launches the terminal UI.
|
|
- `make test` runs `go test ./...`.
|
|
- `./verify.sh` runs the smoke test for the Go VM workflow.
|
|
|
|
## Coding Style & Naming Conventions
|
|
- Go code should stay small, direct, and standard-library-first unless there is a clear reason otherwise.
|
|
- Shell helpers use Bash with `set -euo pipefail`; keep remaining shell scripts strict and explicit.
|
|
- Prefer lowercase filenames with short descriptive names.
|
|
- Use `gofmt` for Go formatting; no extra formatter is configured for shell files.
|
|
|
|
## Testing Guidelines
|
|
- Primary automated coverage is `go test ./...`.
|
|
- Manual verification for VM lifecycle changes: `./banger vm create`, confirm SSH access, then stop/delete the VM.
|
|
- If you add a new operational workflow, document how to exercise it in `README.md`.
|
|
- For NAT changes, verify both guest outbound access and host rule cleanup, for example with `./verify.sh --nat`.
|
|
|
|
## Commit & Pull Request Guidelines
|
|
- Git history uses short, imperative subjects.
|
|
- Prefer a real commit body when the change affects lifecycle behavior, storage semantics, or host integration.
|
|
- PRs should call out runtime requirements, migration impact, and any host-side verification performed.
|
|
|
|
## Security & Configuration Tips
|
|
- The VM workflow requires `sudo` and `/dev/kvm` access; do not commit secrets.
|
|
- `id_ed25519` lives inside the runtime bundle; rotate or replace it before publishing a shared bundle.
