## Summary
Implements [ADR-0030](../docs/decisions/0030-dockerised-dev-mode.md) (now `accepted`): a Docker Compose `apps` profile that runs the three Nx dev servers (`portal-bff`, `portal-shell`, `portal-admin`) from a shared `Dockerfile.dev`, so a developer can boot the whole stack with **no native Node/pnpm**:
```bash
./infra/local/dev.sh up apps # infra + portal-bff:3000 + portal-shell:4200 + portal-admin:4300
```
Purely additive and profile-gated — the native `nx serve` flow and the devcontainer are untouched. Dev-only; no production images (those stay with the ADR-0028 Container Registry work).
## What lands
| File | Change |
| --- | --- |
| `docs/decisions/0030-dockerised-dev-mode.md` | Status `proposed` → `accepted`. |
| `docs/decisions/README.md` | Index status → `accepted`. |
| `infra/local/Dockerfile.dev` | **New.** `node:24-bookworm` + corepack (pnpm resolved from `packageManager` at runtime — no pinned version to drift). No COPY/install at build time. `NX_DAEMON=false`, `NODE_OPTIONS=--max-old-space-size=4096`. |
| `infra/local/dev-entrypoint.sh` | **New.** Shared entrypoint: BFF (`APF_ROLE=bff`) runs `prisma generate` + `prisma migrate deploy` then serves; SPA services go straight to `nx serve`. |
| `infra/local/dev.compose.yml` | **New `apps` profile.** A one-shot `apps-deps` service installs into a shared `node_modules` volume once (the 3 servers gate on its `service_completed_successfully`, avoiding a 3-way install race); `portal-bff` / `portal-shell` / `portal-admin` services from the shared image via a `x-app-base` anchor. Repo bind-mounted; `node_modules` + `.nx` in named volumes. |
| `infra/local/dev.sh` | `apps` added to `ALL_PROFILES` (so teardown / status / logs catch it) + usage / examples. |
| `infra/README.md` | New "Dockerised app dev mode" section + cheat-sheet / file-table rows. |
| `docs/setup/01-dev-debian-vm-setup.md` | "Three dev modes — which when" table at the top of Step 5. |
| `CLAUDE.md` | Architecture roll-up bullet + ADR-count line + environment-conventions note. |
## Key design decisions
- **One image, one install.** The monorepo means a single `Dockerfile.dev` + a single `pnpm install` serves all three apps.
- **`node_modules` + `.nx` in named volumes, not bind-mounted.** The container's install (native modules — `esbuild`, `@swc/core`, Prisma engines, `lmdb`, `@parcel/watcher` — built for this image) must never be shadowed by the host's `node_modules`. The repo source is bind-mounted for hot reload; these two directories are overlaid with named volumes.
- **`apps-deps` one-shot avoids the install race.** Three services sharing one `node_modules` volume can't all run `pnpm install` concurrently. A dedicated install service runs first; the three app services `depends_on` its completion.
- **`NX_DAEMON=false`** in the containers — three containers sharing one workspace would otherwise contend on the Nx daemon.
- **Env wiring.** The BFF reuses its own `apps/portal-bff/.env` (Entra / session / jwks secrets) via `env_file: { required: false }`; the host-specific URLs (`DATABASE_URL` / `REDIS_URL` / OTel endpoint) are overridden in `environment:` — rebuilt from `infra/local/.env` creds → Compose service names. Compose `environment` wins over `env_file`, so the localhost values in the BFF `.env` don't leak into the container.
- **BFF still needs its secrets.** "No native toolchain" ≠ "no config". `apps/portal-bff/.env` must exist (same as native dev); `required: false` lets SPA-only devs `up` without it (the BFF then fails its own boot validators with a clear message).
## Validation on the VM
- [x] `docker compose -f dev.compose.yml --profile apps config` validates (YAML, anchors / merge, env interpolation).
- [x] `bash -n` clean on `dev-entrypoint.sh` and `dev.sh`.
- [x] **Full boot on vm-dev** — `./infra/local/dev.sh up apps` brings up postgres / redis / otel + `apps-deps` (one-shot, exit 0) + portal-bff / portal-shell / portal-admin, all containers report healthy or running.
- [x] `apps-deps` populates the shared `node_modules` volume; the three servers reach their `nx serve` step without re-installing.
- [x] Ports published as expected: BFF :3000, portal-shell :4200, portal-admin :4300.
- [x] `./infra/local/dev.sh up` (no `apps`) unchanged for native devs.
## Follow-ups identified during VM validation
- **SPA → BFF reachability from a remote browser.** Opening `http://<vm-ip>:4200/` from the workstation surfaces a "Backend unreachable" message: the SPA's hardcoded `bffApiBaseUrl: 'http://localhost:3000/api'` (ADR-0018 build-time env) plus the BFF's `CORS_ALLOWED_ORIGINS=http://localhost:4200,…` both assume "browser on the same machine as the BFF", which doesn't hold here. Fixed in the **stacked follow-up PR `feat/spa-dev-proxy`** (proxy `/api` in the Angular dev-server + relative `bffApiBaseUrl`), which lands right after this PR.
- The OTel HTTP exporter URL (`environment.otlpEndpoint`) and the cross-SPA links (`adminAppUrl`, `shellAppUrl`) remain absolute and hit the same remote-browser limit; not blocking for v1, can be revisited if needed.

Documentation index
This is the entry point to all project documentation. It is maintained automatically: any addition, rename, or removal of a .md file under docs/ must be reflected here in the same change.
Conventions
- Documentation is written in English.
- One topic per file. Group related files into a folder when there are three or more.
- Cross-reference with relative links so they keep working in GitHub, IDEs, and exported sites.
- For architectural decisions, do not add them here — they belong in decisions/ as MADR 4.0.0 ADRs.

Daily development
- development.md — repo layout, prerequisites, initial setup, daily commands, observability dev-loop (Jaeger UI, log ↔ trace correlation), dependency updates (Renovate), conventional commit cycle. Day-to-day reference for working on the project.
Architecture
- architecture.md — cross-cutting Mermaid diagrams: C4 system context, C4 containers, Nx module boundaries, CI/CD pipeline. Single-decision diagrams (auth sequence, ERD, etc.) live inline in their ADR.
