From 04a17dfa018b9207bc4d39f709b60d78a0ce1c10 Mon Sep 17 00:00:00 2001 From: Yumin Chen Date: Wed, 15 Apr 2026 06:45:17 +0100 Subject: [PATCH 1/4] feat: implement OCI container and compose subsystems 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. --- .github/workflows/container-tests.yml | 547 +++++++ Cargo.lock | 190 ++- README.md | 37 + crates/perry-codegen/src/lower_call.rs | 116 ++ crates/perry-container-compose/Cargo.toml |

This update moves the stack from "spec-complete" to "deployment-hardened." Orchestration & Correctness: - Project Namespacing: Volumes and networks are now prefixed with `_` to prevent cross-stack collisions and data corruption. - Idempotency: Implemented spec-hash tracking (`perry.compose.spec_hash`); subsequent `up()` calls now detect drift and recreate containers only on configuration changes. - DNS & Aliases: Automated service-key network aliases, allowing sibling containers to resolve each other (e.g., `db:5432`) via embedded DNS. - Rollback & Cleanup: Fixed volume-drain bugs in `down()`; added RAII-style `downByProject` and `downAll` APIs for reliable resource recovery. Codegen & FFI Fixes: - Fixed FFI type mismatches where LLVM doubles conflicted with Rust i64/i32 signatures for handles. - Resolved "Invalid Handle" bugs via NaN-boxing with `POINTER_TAG` for safe u64-to-f64 handle round-trips. - Implemented `js_value_to_str_ptr_for_ffi` to correctly handle JSON serialization for complex objects passed to `composeUp`. - Fixed async backend race conditions via synchronous in-place probes. Security & Environment: - Enforced `PolicySpec` tiers (Isolated, Hardened, Untrusted) with fail-fast checks for backend compatibility. - Added three-mode image verification (off, warn, enforce) via Sigstore/cosign. - Integrated `${VAR:-default}` environment interpolation at the FFI boundary. Testing & Validation: - Phase A-E Test Sweep: 191+ tests covering hermetic functional logic, FFI regressions, live-runtime integration (Docker/Podman), and e2e compiler-to-runtime flows. - Forgejo Deployment: A production-quality example using `data.forgejo.org`, featuring healthcheck-gated dependencies and stable volume secrets.

Backend capabilities + spec normalization. +//! +//! ## Why this module exists +//! +//! Perry's `ContainerSpec` and `ComposeSpec` are *abstractions over OCI*, +//! but the four backends Perry can pick at runtime — Docker, Podman, +//! apple/container, Lima/nerdctl — diverge sharply on which features +//! they actually support. A spec written for Docker that sets +//! `privileged: true` and `seccomp: "/etc/seccomp.json"` is meaningless +//! on apple/container (no privileged mode, no seccomp profiles); silently +//! emitting those flags produces opaque CLI errors at runtime, and +//! silently dropping them produces a **less secure** container than the +//! user asked for, with no signal that the policy wasn't honored. +//! +//! The fix is a three-layer dance: +//! +//! 1. **Capabilities** — every backend declares what it actually supports +//! in a `BackendCapabilities` struct. This is the contract: the +//! feature names are stable across backends, but the values diverge. +//! +//! 2. **Normalization** — before the orchestrator hands a `ContainerSpec` +//! to a `CliProtocol::run_args`, it runs `normalise_spec_for(backend, +//! spec)`. This pass either (a) translates the feature to the +//! backend's closest equivalent (e.g., docker `--security-opt seccomp= +//! file` → podman `--security-opt seccomp=file` ✅; apple drop with +//! warning), (b) emits a structured `NormalizationWarning` the +//! orchestrator surfaces to the user, or (c) raises a hard error if +//! the user opted into `enforcement: Strict` mode. +//! +//! 3. **Conformance test suite** — `tests/conformance.rs` runs the same +//! arg-shape assertions against every protocol's `run_args` / +//! `create_args` / `list_args` / etc. The "did backend N emit the +//! same shape as backend M?" question becomes a CI-blocking unit +//! test, not a runtime surprise. +//! +//! ## Determinism guarantees +//! +//! Given the same `ComposeSpec`, normalise-then-emit produces: +//! +//! - **Same containers, same names, same labels, same volumes/networks** +//! on every backend. Project-namespacing (`_`) and +//! service-key network aliases are computed at the engine layer above +//! the protocol, so they're invariant. +//! - **Best-effort feature parity** for security flags: features that +//! land natively on the target runtime are emitted; features that +//! don't are either translated (Docker's `--read-only` ↔ apple's +//! `--read-only`), dropped with warning, or hard-rejected. +//! - **JSON output normalization** at the parse layer: `parse_list_output` +//! on every protocol returns the **same `ContainerInfo` struct** with +//! the same field semantics — so user code reading `info.status` sees +//! `"running"` from any backend, not `"Up 5 seconds"` from docker +//! vs `"running"` from apple. +//! +//! ## What this module does NOT solve +//! +//! - **Network plugin model** — apple/container's network plugin needs +//! `container system start`; Docker daemons need to be running. Both +//! are operational state, not feature state, so they're caught by +//! `check_available()` in the existing trait. +//! - **Performance characteristics** — apple/container runs in a VM, +//! Docker on macOS runs in a VM, podman rootless runs in user-namespace. +//! Container startup time and disk I/O speed differ; that's outside +//! the scope of "did the spec reach the runtime intact". +//! - **Image registry auth** — each backend has its own credential helper +//! (docker `~/.docker/config.json`, podman `~/.config/containers/auth. +//! json`, apple's keychain integration). Auth is operational state +//! handled by the runtime; Perry doesn't try to bridge. + +use crate::types::ContainerSpec; +use std::collections::BTreeSet; + +/// What a backend can do.

The Forgejo example pins explicit `container_name` values: + +```typescript,no-test +const dbHostname = "forgejo-db"; +const forgejoHostname = "forgejo-app"; + +services: { + db: { + image: `postgres:${pgVersion}`, + container_name: dbHostname, // ← stable target + // … + }, + forgejo: { + image: `data.forgejo.org/forgejo/forgejo:${version}`, + container_name: forgejoHostname, + environment: { + FORGEJO__database__HOST: `${dbHostname}:5432`, // ← refers to it + // … + }, + }, +}, +``` + +See [Networking → Cross-service DNS](./networking.md#cross-service-dns) +for the full backstory and why this is the workaround until +service-key network-alias support lands. + +## OpenSSH on :22 + `START_SSH_SERVER=false` + +Forgejo's official image runs `/usr/sbin/sshd` on container port 22 in +its entrypoint script, then runs the forgejo binary. If you also set +`FORGEJO__server__START_SSH_SERVER=true`, forgejo's Go-based built-in +SSH server tries to bind :22 too — and the container exit-0's with +"bind: address already in use". + +The standard Forgejo deployment pattern is to **let OpenSSH handle SSH +on :22 and tell forgejo not to start its own**: + +```typescript,no-test +environment: { + FORGEJO__server__START_SSH_SERVER: "false", // ← critical + FORGEJO__server__SSH_PORT: "2222", // public host port + FORGEJO__server__SSH_LISTEN_PORT: "22", // container-internal port + // … +}, +``` + +Forgejo writes git users' authorized_keys to `/data/git/.ssh/`, which +the in-container OpenSSH consumes. Git operations route through sshd on +:22, then forgejo's `gitea-shell` script. + +## Healthcheck-gated dependency startup + +postgres takes ~5–10 seconds to initialise on first run (initdb + +listener bind). Without gating, forgejo starts immediately, can't +connect, and burns retry budget. The fix is a per-service +`healthcheck` plus `depends_on: { svc: { condition: 'service_healthy' +} }`: + +```typescript,no-test +db: { + image: "postgres:16-alpine", + // … + healthcheck: { + test: ["CMD-SHELL", "pg_isready -U forgejo -d forgejo"], + interval: "5s", + timeout: "3s", + retries: 10, + start_period: "30s", + }, +}, +forgejo: { + // … + depends_on: { db: { condition: "service_healthy" } }, +}, +``` + +Even with that, the example *also* runs an explicit readiness loop +post-`up()` for the full HTTP `/api/healthz` path — the healthcheck +gates **container startup** but the operator banner shouldn't print +until the API is *serving*: + +```typescript,no-test +async function waitForForgejo(stack: number, timeoutMs: number): Promise { + const deadline = Date.now() + timeoutMs; + while (Date.now() < deadline) { + try { + // Probe from INSIDE the forgejo container so the docker-proxy + // bind-up window doesn't trip the host-side curl. + await exec(stack, "forgejo", [ + "wget", "-q", "-O", "/dev/null", + "--timeout=2", "--tries=1", + "http://127.0.0.1:3000/api/healthz", + ]); + return true; + } catch (_e) { + await new Promise((r) => setTimeout(r, 2000)); + } + } + return false; +} +``` + +`/api/healthz` is Forgejo's no-auth liveness endpoint that returns 200 +once the web server is up AND the database / cache subsystems pinged +successfully. Don't use `/api/v1/version` — when +`REQUIRE_SIGNIN_VIEW=true` (a production-hardening default) it returns +401, and `wget` exits non-zero on HTTP error responses. + +## Stable secrets for redeploy + +The Forgejo example's `buildConfig()` uses **truthy-fallback** semantics +for env vars (`process.env[name] || fallback`) because Perry's +`process.env[NONEXISTENT]` returns an empty-ish value where strict +equality to `undefined` / `''` doesn't hold: + +```typescript,no-test +function envOr(name: string, fallback: string): string { + return (process.env[name] as string | undefined) || fallback; +} +``` + +The defaults for the three secret-bearing fields are random hex: + +```typescript,no-test +dbPassword: envOr('FORGEJO_DB_PASSWORD', randomHex(32)), +secretKey: envOr('FORGEJO_SECRET_KEY', randomHex(32)), +internalT: envOr('FORGEJO_INTERNAL_TOKEN', randomHex(52)), +``` + +This is fine for **first-run** / dev / smoke-test, but **breaks any +subsequent run against the same volumes** because: + +- Postgres rows were authored under the prior password — new password + rejects the connection. +- Forgejo's `/data/gitea/conf/app.ini` is encrypted with the prior + `SECRET_KEY` — Forgejo can't decrypt it on startup. + +For production, **set them to stable values** via an `.env` file or a +secrets manager: + +```bash +# .env +FORGEJO_DB_PASSWORD=$(openssl rand -hex 32) +FORGEJO_SECRET_KEY=$(openssl rand -hex 32) +FORGEJO_INTERNAL_TOKEN=$(openssl rand -hex 52) + +# deploy.sh +source .env +./forgejo_app +``` + +Generate once, store in a secrets manager, redeploy as many times as +needed against the same volumes. + +## First-run admin user + +Forgejo's installer is locked (`INSTALL_LOCK=true`) so the GUI +installer doesn't run on first request.

From 0830b2fed5b5341b76e443bc92c44043599e4b10 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 29 Apr 2026 15:13:58 +0000 Subject: [PATCH 4/4] Implement specified Perry container subsystem enhancements This commit brings the container subsystem to production readiness by aligning the FFI bridge, orchestration logic, and compiler codegen with the provided specification. Changes include: - Updating `ComposeEngine` and `ComposeWrapper` to return structured logs indexed by service, preserving stream separation. - Implementing `remove_orphans` and automatic image building in the compose `up` sequence. - Refining FFI signatures in `perry-stdlib` to use JSON string pointers for complex options and `i64` for numeric arguments, ensuring ABI compatibility with unboxed NaN-boxed doubles. - Enhancing the Perry compiler's codegen to support `NativeArgKind::I64Raw` for correct `fptosi` conversion of numeric FFI parameters. - Enforcing Sigstore image verification for all services in a stack during `composeUp`. - Fixing the `perry-compose` CLI and stdlib tests to match the updated orchestration and FFI contracts. - Adding `perry-container-compose` to workspace members in `Cargo.toml` for build consistency.
