bac224c56d chore: improve docker compose template, tests and docs (#11593)
Replaces the single-file `docker-compose.yaml` quickstart with a
production-aware, Traefik-based compose pack in `deploy/compose/`. The
pack covers the full arc from a 2-minute localhost quickstart to a
hardened homelab or semi-production deployment.

### What's in the pack

**Stack**: Traefik (proxy) → ZITADEL API (Go `:8080`) + ZITADEL Login
(Next.js `:3000`) → PostgreSQL

All HTTP/gRPC routing is handled by Traefik via Docker labels — no
manual proxy config needed. The Login V2 UI is enabled by default. Login
URLs are derived automatically from `ZITADEL_DOMAIN`,
`ZITADEL_EXTERNALPORT`, and `ZITADEL_PUBLIC_SCHEME` — no separate URL
variables needed.

**Compose files**

| File | Purpose |
|------|---------|
| `docker-compose.yml` | Base stack — works standalone. Uses explicit
`name: zitadel` network for reliable Traefik service discovery. |
| `docker-compose.mode-letsencrypt.yml` | TLS overlay: ACME HTTP
challenge |
| `docker-compose.mode-external-tls.yml` | TLS overlay: upstream LB/CDN
terminates TLS. Uses `forwardedHeaders.trustedIPs` (configurable via
`TRAEFIK_TRUSTED_IPS`) instead of `insecure=true`. |
| `docker-compose.mode-local-tls.yml` | TLS overlay: self-signed certs
for LAN |
| `docker-compose.prodlike.yml` | Splits init / setup / start for
controlled upgrades |
| `docker-compose.test.yml` | CI overlay: swaps images to locally-built
`:local` tags |

**Optional profiles**: `cache` (Redis), `observability` (OpenTelemetry
Collector)

### Build infra

- New `@zitadel/api:pack` and `@zitadel/login:pack` Nx targets build
local Docker images (`zitadel/zitadel:local`,
`zitadel/zitadel-login:local`) for use in CI and local testing
- `apps/api/Dockerfile` now accepts a `BINARY` build arg so local and
release builds share the same image

### Testing

- New `@zitadel/compose` Nx project with targets: `test-config`
(validates all overlay combinations using `--quiet`), `test-run` (starts
full stack with local images), `test-e2e` (Playwright wiring + protocol
matrix tests through Traefik), `test-full` (end-to-end: build → start →
test → teardown), `stop`
- **`@zitadel/compose` is explicitly excluded from `nx affected` in CI
for now** — the full stack smoke test requires a Docker daemon and
significant resources. The intent is to add a dedicated
`compose_smoke_test` CI job in a follow-up. The targets can be run
locally with `pnpm nx run @zitadel/compose:test-full`.

### Documentation

- **`compose.mdx`**: Complete rewrite with a staged structure (Stage 1
Quickstart → Stage 2 Homelab → Stage 3 Beyond Compose). Documents TLS
modes, profiles, secrets hardening, ExternalDomain/Port/Secure
invariant, upgrades, and the path to Kubernetes
- **New `requirements.mdx`**: Lists supported PostgreSQL versions
(14–18), Redis (standalone), Docker Compose v2.x, and reverse proxy h2c
requirements
- **`reverse_proxy.mdx`**: Added intro covering h2c requirements, TLS
modes table, and Login UI routing split
- **`troubleshooting.mdx`**: New sections for container restarts on
upgrade, FIRSTINSTANCE env vars not taking effect, and diagnosing
unhealthy containers
- **`caddy/index.mdx`**: Known issue and workaround for the `TE:
trailers` header hang
- Removed the old
`apps/docs/content/self-hosting/deploy/docker-compose.yaml` embedded in
the docs

### Breaking change

The old `apps/docs/content/self-hosting/deploy/docker-compose.yaml` file
is deleted. The getting-started docs page
(`/self-hosting/deploy/compose`) now points to the new pack via a `curl
| tar` download command.

---

### Checklist

- [x] `deploy/compose/` smoke test passes end-to-end locally (`pnpm nx
run @zitadel/compose:test-full`)
- [x] Docs build passes (`pnpm nx run @zitadel/docs:build`)
- [ ] Follow-up issue created to add `compose_smoke_test` CI job

# ZITADEL API App Guide for AI Agents
## Context
The **API App** (`apps/api`) is the Nx application target for building and running the Go backend. Most backend implementation lives in `internal/`, while this project orchestrates build, generate, lint, and test workflows.
## Source of Truth
- **Go Toolchain**: Inspect root `go.mod` before Go work.
- **API Design Contract**: Follow `API_DESIGN.md` for service and resource conventions.
- **Domain Logic Location**: For implementation details, also read `internal/AGENTS.md`.
## Verified Nx Targets
- **Run API (prod profile)**: `pnpm nx run @zitadel/api:prod`
- **Build**: `pnpm nx run @zitadel/api:build`
- **Generate (all)**: `pnpm nx run @zitadel/api:generate`
- **Install Proto Plugins**: `pnpm nx run @zitadel/api:generate-install` — installs all Go-based proto plugins (`buf`, `protoc-gen-go`, `protoc-gen-connect-go`, `protoc-gen-openapiv2`, `protoc-gen-validate`, `protoc-gen-authoption`, etc.) to `.artifacts/bin/$(GOOS)/$(GOARCH)/`. Output is Nx-cached; only reruns when plugin versions or local protoc sources change.
- **Lint**: `pnpm nx run @zitadel/api:lint`
- **Test (all)**: `pnpm nx run @zitadel/api:test`
- **Test (unit)**: `pnpm nx run @zitadel/api:test-unit`
- **Test (integration)**: `pnpm nx run @zitadel/api:test-integration`
- **Build Linux**: `pnpm nx run @zitadel/api:build-linux` — cross-compiles a Linux binary for Docker packaging
- **Pack (Docker)**: `pnpm nx run @zitadel/api:pack` — builds a local Docker image `zitadel/zitadel:local`. Requires Docker daemon.
## Generation Notes
- `@zitadel/api:generate` can update generated, tracked files (stubs/assets/statik). Run it intentionally.
- API changes in `proto/` often require regenerating API, package, and docs artifacts.
- Proto plugins are installed to `.artifacts/bin/` — do not commit these binaries; they are declared as Nx outputs and restored from cache.
