gsxdsm b4856e3c1e fix: separate Docker app root from project mount so -v host mounts work (#2414)
The runner stage installed the application at /project, which was also the
documented bind-mount point — mounting a host project there shadowed the CLI
and the container exited with MODULE_NOT_FOUND on packages/cli/dist/bin.js.

- Install the app under /app and run the entrypoint by absolute path.
- Reserve /workspace (empty in the image, container workdir) as the project
  mount point.
- Update docs/docker.md: mount at /workspace, and document that embedded
  Postgres/global state lives in /home/node/.fusion with a named-volume
  example so persistence actually captures it.

Verified: image builds; `docker run -v host:/workspace` boots, embedded
Postgres initializes, /api/health returns ok.

Fixes #2414

# Running Fusion in Docker
This guide shows how to build and run Fusion in a container.
> This document is about containerizing Fusion itself (`docker build` / `docker run`).
> For managed Docker mesh-node provisioning architecture (services, routes, mesh config flow, and `4041` vs reserved `4040` port convention), see [Architecture → Docker Node Provisioning](./architecture.md#docker-node-provisioning).
## Build the image
```bash
docker build -t fusion .
```
## Run the dashboard
Mount your project into `/workspace` and publish the dashboard port:
```bash
docker run -p 4040:4040 -v /path/to/project:/workspace fusion
```
The application itself is installed under `/app`; `/workspace` is reserved for
your project and is the container's working directory. Do not mount over `/app`.
By default, the container runs:
```bash
fn dashboard
```
on port `4040`.
## Environment variables
Pass provider credentials and integrations with `-e` flags:
```bash
-e ANTHROPIC_API_KEY=...
-e OPENAI_API_KEY=...
-e GITHUB_TOKEN=...
-e FUSION_DASHBOARD_TOKEN=fn_your_stable_token # optional; persists across restarts
```
Add any other provider keys your setup requires (for example `OPENROUTER_API_KEY`).
### Dashboard authentication
The dashboard is bearer-token protected by default. In a container the
auto-generated token appears in `docker logs` on startup — copy it, or set
`FUSION_DASHBOARD_TOKEN` (or the back-compat `FUSION_DAEMON_TOKEN`) to a
stable value so the token survives restarts. See
[CLI reference → fn dashboard → Authentication](./cli-reference.md#fn-dashboard)
for the full flow.
## Pass additional CLI flags
You can append normal CLI arguments after the image name:
```bash
docker run fusion dashboard --port 8080
```
If you change the dashboard port, also update Docker port mapping:
```bash
docker run -p 8080:8080 fusion dashboard --port 8080
```
## Persistence
Fusion keeps state in two places inside the container:
- **Per-project state** — `.fusion/` under the mounted project (`/workspace/.fusion`).
This is covered automatically by the `/workspace` project mount.
- **Global state** — `/home/node/.fusion` (embedded PostgreSQL data, global
settings, agents). This is *not* under `/workspace`, so mount it separately if
you want it to survive container removal:
```bash
docker run -p 4040:4040 \
-v /path/to/project:/workspace \
-v fusion-home:/home/node/.fusion \
fusion
```
The named volume `fusion-home` persists the embedded database across
`docker run` invocations; a host directory bind mount works too.
## Complete example
```bash
docker run --rm \
-p 4040:4040 \
-v /path/to/project:/workspace \
-v fusion-home:/home/node/.fusion \
-e ANTHROPIC_API_KEY=your_key \
-e OPENAI_API_KEY=your_key \
-e GITHUB_TOKEN=your_token \
fusion dashboard --port 4040
```
## Notes
- The container runs as the non-root `node` user.
- `git` must be available in the container runtime. The mounted project volume must preserve `.git` metadata and repository history for worktree operations; Fusion initializes missing repositories during project registration.
- The root `Dockerfile` installs with `pnpm install --frozen-lockfile` before copying full source, so every current workspace package/plugin manifest selected by `pnpm-workspace.yaml` must be covered by a builder-stage `COPY` before that install. Keep the manifest-only dependency-cache layer; the runner's intentionally filtered production install does not provide builder coverage.
- `scripts/__tests__/dockerfile-workspace-manifests.test.mjs` expands the current workspace entries and rejects missing or duplicate builder pre-install COPY sources. Run it with `pnpm test:scripts -- scripts/__tests__/dockerfile-workspace-manifests.test.mjs` whenever workspace membership or Docker manifest copies change.
