# Running OpenConcho in Docker
The `@openconcho/web` SPA can be served from a container. The image is a
two-stage build: Node + pnpm builds the static bundle, then
`nginx-unprivileged` serves it on port `8080` as a non-root user.
## Build and run
```bash
docker build -t openconcho-web .
docker run --rm -p 8080:8080 openconcho-web
# → http://localhost:8080
```
Hardened run (read-only filesystem, no added capabilities):
```bash
docker run --rm -p 8080:8080 \
--read-only \
--tmpfs /tmp \
--tmpfs /var/cache/nginx \
--cap-drop ALL \
--security-opt no-new-privileges \
openconcho-web
```
`GET /healthz` returns `200 ok` for container health checks.
## CORS
The desktop app routes HTTP through Rust (`reqwest`), so it is **not** subject
to browser CORS. The **web build is**: it uses the browser's `fetch`, so every
request to your Honcho API is cross-origin. Honcho calls are `POST` +
`application/json` + `Authorization: Bearer`, which the browser always
**preflights** (`OPTIONS`). You must handle this one of two ways.
### Option 1 — configure Honcho's CORS (recommended)
Honcho is a FastAPI service. Allow the UI's origin via its
`CORSMiddleware` so preflight and actual requests succeed:
```python
app.add_middleware(
CORSMiddleware,
allow_origins=["http://localhost:8080"], # the OpenConcho origin
allow_methods=["*"],
allow_headers=["*"],
)
```
This fits OpenConcho's model directly — the UI keeps using the absolute Honcho
URL you enter in Settings (stored in `localStorage`). Since you self-host
Honcho, you control this.
### Option 2 — same-origin reverse proxy (advanced)
Proxy the Honcho API under the same origin that serves the SPA, so the browser
sees same-origin requests and CORS never applies (the token also never crosses
origins). Uncomment the `location /honcho/` block in
[`docker/nginx.conf`](../docker/nginx.conf) and set `proxy_pass` to your Honcho
host.
Caveat: the Settings form currently validates the base URL as an **absolute**
URL (`z.string().url()`), so pointing the UI at a relative same-origin path
(`/honcho`) isn't wired yet. Until that lands, Option 1 is the supported path.
