It speaks an OCI-compatible spec but its CLI +// surface diverges from `docker` on several axes that matter for an +// orchestrator. The pre-v0.5.374 implementation delegated 80% of arg +// construction back to DockerProtocol, which produced silent breakage +// on common ops (`pull`, `images`, `inspect`, `logs --tail` etc.). Each +// divergence below is annotated with the CLI evidence; verified against +// `container CLI version 0.12.0`. +// +// **Subcommand differences**: +// +// - Image ops live under `image` (`container image pull`, +// `container image list`, `container image delete`, +// `container image inspect`). Docker exposes them at top level +// (`docker pull`, `docker images`, `docker rmi`, `docker inspect`). +// +// - Container list is `list` / `ls` — there is **no `ps`** alias. +// +// - Container removal is `delete` (with `rm` accepted as alias). Volume +// and network removal both use `delete`. +// +// **Flag differences**: +// +// - `logs` uses `-n `, not `--tail `. +// - `inspect` outputs JSON natively — does **not** accept `--format`. +// - `volume create` does **not** accept `--driver` (driver model is +// implicit; only `--label`, `--opt`, `-s` are valid). +// - `run` does **not** support `--privileged`, `--security-opt`, +// `--restart`, `--ipc`, or `--pid`. Apple silently warns + may reject. +// - `run` requires explicit `--detach` for the orchestrator's +// "create-and-start, return ID" semantics. Pre-fix the engine +// blocked on the container's main process. +// - JSON shapes diverge: list / inspect / image-list each have their +// own field naming (`configuration.id`, `image.reference`, etc.). +// +// **Apple-only flags we propagate when set on `ContainerSpec` (extension +// fields are forward-compatible no-ops on Docker)**: +// +// - `--arch` / `--os` / `--platform` for cross-arch image pulls. +// - `--rosetta` for x86_64-on-arm64 translation. +// - `--virtualization` for nested virt. +// - `--ssh` for SSH agent forwarding. +// +// These aren't on `ContainerSpec` today; the orchestrator wires them in +// only on apple/container until they're standardized. +pub struct AppleContainerProtocol; + +impl CliProtocol for AppleContainerProtocol { + fn capabilities(&self) -> &'static crate::capabilities::BackendCapabilities { + &crate::capabilities::BackendCapabilities::APPLE + } + + fn run_args(&self, spec: &ContainerSpec) -> Vec { + // `run` is foreground by default.

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.

Two networks is the cleanest expression of +that split. + +## Stable container names for cross-service DNS + +Perry's compose engine creates each container with a `{md5}-{random}` +derived name and doesn't yet register the service KEY (`db`, +`forgejo`) as a network alias. So +`FORGEJO__database__HOST: 'db:5432'` would fail name resolution at +runtime. 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.

So +`forgejo-pgdata` is created as the docker volume `forgejo-pgdata`, and +two stacks both declaring `forgejo-pgdata` would share it. + +For multi-stack isolation, prefix the volume name with the project / +stack identifier: + +```typescript,no-test +volumes: { + "myapp-staging-pgdata": { driver: "local" }, + "myapp-production-pgdata": { driver: "local" }, +}, +``` + +## Inspecting volume state + +The `perry/container` and `perry/compose` modules don't expose a JS +`inspectVolume()` helper today — for now, inspect with the underlying +runtime CLI: + +```bash +docker volume ls --filter name=app- # list app-prefixed volumes +docker volume inspect app-pgdata # mountpoint, driver, labels +docker run --rm -v app-pgdata:/data \ # mount + inspect contents + alpine ls -la /data +``` + +## Backup patterns + +The standard "tar the volume into the host" backup recipe: + +```bash +docker run --rm -v app-pgdata:/data:ro -v $(pwd):/backup alpine \ + tar czf /backup/pgdata-$(date +%F).tar.gz -C /data . +``` + +For a pure-Perry approach, drive that with `perry/container.run()`: + +```typescript,no-test +await run({ + image: "alpine:3.19", + cmd: ["sh", "-c", + "tar czf /backup/pgdata-$(date +%F).tar.gz -C /data ."], + volumes: [ + "app-pgdata:/data:ro", + "./backups:/backup", + ], + rm: true, +});
