feat: implement production-ready container and workload orchestration
Finalize the OCI stack by implementing the `perry/container` and
`perry/container-compose` (workloads) subsystems. This moves the
implementation from initial stubs to a hardened, spec-compliant architecture.
Core Subsystems:
- Orchestration: Implemented `WorkloadGraphEngine` and `ComposeEngine`
using Kahn's algorithm for deterministic dependency resolution and
topological startup/shutdown/rollback.
- Backend Logic: Multi-layered auto-detection for 7+ runtimes (Apple, Podman,
Docker, Lima, etc.) with liveness probes and strict priority ordering.
- Security & Policy:
* Implemented `PolicySpec` enforcement (Isolated, Hardened, Untrusted).
* Added image verification via Sigstore/cosign (opt-in via environment).
* Hardened ephemeral runners with `cap_drop: ALL`, seccomp, and read-only
root support.
- FFI Bridge: Expanded `perry-stdlib` with async-safe, promise-based
handlers optimized for raw C-ABI passing of primitives.
Technical Details:
- Restructured `perry-container-compose` into a flat module layout.
- Standardized container naming to `{image_hash_8}-{random_hex8}` with
label-based orphan cleanup.
- Refactored `CliBackend` to be generic over `CliProtocol` for zero vtable
overhead.
- Modernized internal registries with `DashMap` for concurrent access.
- Integrated with Perry compiler (HIR registration and codegen dispatch).
Refinements & Fixes:
- Fixed SQLite linker conflicts by gating runtime stubs.
- Restored `Buffer` synonym and `process.argv` specialization in `lower.rs`.
- Implemented robust IP and label extraction for the `DockerProtocol`.
- Expanded `MockBackend` for high-fidelity orchestration testing.
Validation:
- Added 12 new tests covering orchestration states and policy enforcement.
- Verified 79/0 pass in `perry-container-compose`.
- Verified 33/0 pass in `perry-stdlib` container features and smoke tests.
…rfaced by running it (v0.5.371)
Replaces example-code/forgejo-deployment with a production-quality
deployment using the real Forgejo image — `data.forgejo.org/forgejo/
forgejo:11`, the official Forgejo OCI registry that's separate from
codeberg.org's gated mirror, no Gitea fallback. Driven by running the
example end-to-end against live Docker, surfaced and fixed nine
interlocking codegen + FFI + orchestration bugs that together blocked
any non-trivial compose stack from running.
CODEGEN / FFI fixes (composeUp / down / handle round-trip):
1. composeUp({...}) failed at JSON parse — codegen StrPtr arm passed
raw object pointer through `js_get_string_pointer_unified`, FFI
read it as StringHeader. New runtime helper
`js_value_to_str_ptr_for_ffi` returns the heap string pointer for
actual strings/SSO and otherwise routes through `js_json_stringify`
for object/array/number/bool args.
2. getBackend() returned "unknown" before any async FFI — BACKEND
OnceLock was empty. js_container_getBackend now does a synchronous
in-place probe (block_in_place inside a tokio worker, fresh
current_thread runtime otherwise).
3. composeUp Promise resolved with f64=5e-324 (subnormal). Bare u64
handles in the result_bits slot decoded as f64 bits; `${stack}`
interpolation printed "0". `handle_to_promise_bits(id)` NaN-boxes
with POINTER_TAG | (id & POINTER_MASK); Ok(0u64) void resolutions
become PROMISE_VOID_BITS = TAG_UNDEFINED. Swept across 23 sites.
4. down(stack, opts) failed with "Invalid compose handle". Codegen
dispatch `args: &[NA_F64, NA_F64]` lowered both args to LLVM
double, but Rust signatures took (handle_id: i64, volumes: i32) —
calling-convention mismatch. Changed every compose handle-arg FFI
signature to (handle: f64, ...) and added handle_id_from_f64
helper.
5. exec(stack, 'svc', cmd) failed with "No such container".
service::service_container_name regenerated random suffix per call.
Added `service_container_names: Mutex<HashMap>` cache to
ComposeEngine populated by up()'s start loop.
6. ${VAR:-default} env interpolation didn't apply to TS-side specs —
postgres bombed with "FATAL: invalid character in extension owner"
because literal placeholder strings flowed through. Wired
`perry_container_compose::yaml::interpolate` into parse_compose_spec
so ${VAR} expansion happens before serde_json::from_str (matches
SPEC §7.8 / §7.9 — same engine, FFI boundary).
7. down(stack, { volumes: false }) silently REMOVED volumes.
js_compose_down took (handle: f64, volumes: f64) but TS users pass
an options object. The object NaN-boxed to a non-zero pointer →
`volumes != 0.0` → remove_volumes flipped to true. Changed dispatch
to `[NA_F64, NA_STR]`; FFI parses the JSON-encoded DownOptions
server-side via serde_json (same shape as composeUp).
8. ComposeEngine::down() called rollback() unconditionally, which
drains session_volumes regardless of the volumes-preserve flag.
Snapshot+restore around rollback when remove_volumes=false.
9. types/perry/compose/index.d.ts was missing `healthcheck`, `user`,
`working_dir`, `read_only`, `privileged`, `cap_add`, `cap_drop`
on Service plus `internal`, `driver_opts`, `labels` on
ComposeNetwork — runtime supported them, TS surface didn't.
Added a `Healthcheck` interface (compose-spec §service.healthcheck:
test, interval, timeout, retries, start_period, disable) and
extended both interfaces.
EXAMPLE structure (example-code/forgejo-deployment/main.ts):
- Two-service stack: postgres:16-alpine + data.forgejo.org/forgejo/
forgejo:11.
- depends_on: { db: { condition: 'service_healthy' } }.
- Per-service compose-spec healthchecks: pg_isready for postgres,
wget /api/healthz for forgejo.
- Explicit container_name on each service so Docker's embedded DNS
routes forgejo→forgejo-db (Perry's compose engine doesn't yet
register the service-key as a network alias; documented).
- Internal-only forgejo-db-net (postgres unreachable from host or
sibling stacks); public forgejo-web-net for forgejo's web + SSH
ports.
- Standard Forgejo "OpenSSH on port 22 + START_SSH_SERVER=false"
configuration — the inline-Go SSH server conflicts with the
entrypoint's sshd otherwise (exit-0 with "bind: address already
in use").
- Lifecycle:
./forgejo_app deploy + verify-healthz + exit 0
./forgejo_app --down tear down (preserves volumes)
FORGEJO_DESTROY_ON_EXIT=1 ./forgejo_app --down also drops
volumes
Perry's `process.on('SIGINT', ...)` handler isn't actually invoked
at runtime (confirmed by probe — kill -INT after register; setInterval
keeps ticking), so the example uses `docker compose up -d` style:
exit 0 after success, separate --down command for teardown.
- Production note in doc-comment: FORGEJO_SECRET_KEY,
FORGEJO_INTERNAL_TOKEN, FORGEJO_DB_PASSWORD MUST be stable across
redeploys against the same volumes (random defaults break
Forgejo's encrypted-config decryption + postgres rows).
- Local `tsconfig.json` with paths: { "perry/*": ["../../types/
perry/*"] } for IDE typechecking + `perry-globals.d.ts` declaring
the subset of `process` Perry actually exposes (env, exit, on,
argv, cwd, platform — minimal, not @types/node).
- Workspace re-registration: re-added perry-container-compose to
[workspace] members + default-members + [workspace.dependencies].
VERIFIED full lifecycle:
fresh up → containers healthy, /api/healthz returns "pass"
--down preserve → containers gone, volumes intact
redeploy → containers come back, Forgejo decrypts existing
config (stable secrets), healthz passes again
--down destroy → containers + volumes + networks all gone

…container/ section
Seven new pages cover overview, single-container lifecycle (perry/container), compose orchestration (perry/compose), networking (incl. the container_name DNS workaround), volumes, security, and a Forgejo-deployment case study. New docs/examples/stdlib/container/snippets.ts with 11 ANCHOR blocks pulled into the markdown via {{#include}}. doc-tests --lint and --filter container both pass.
- Refine platform candidate priority and liveness checks (Spec §5.2) - Align container naming with service YAML configuration MD5 (Spec §8.1) - Standardize FFI signatures with f64 parameters and JSON options (Spec §9.1) - Synchronize codegen dispatch tables with updated FFI signatures - Enforce image verification in compose orchestration flow (Spec §11.2) - Register perry-container-compose as a workspace member in Cargo.toml Co-authored-by: yumin-chen <10954839+yumin-chen@users.noreply.github.com>
