 # OSC-Docker
 
-A docker image for Open Stage Control
+Docker image for the Open Stage Control node-only release.
+
+This image uses the upstream release artifact instead of building Electron from source. I verified on May 10, 2026 that Framagit's current release is `v1.30.3`, and that it publishes a `Node.js` package at:
+
+`https://openstagecontrol.ammd.net/packages/open-stage-control_1.30.3_node.zip`
+
+Source project:
+
+`https://framagit.org/jean-emmanuel/open-stage-control`
+
+## Build
+
+```bash
+docker build -t open-stage-control .
+```
+
+To target a different upstream release:
+
+```bash
+docker build \
+  --build-arg OPEN_STAGE_CONTROL_VERSION=1.30.3 \
+  -t open-stage-control .
+```
+
+## Run
+
+```bash
+docker run --rm \
+  -p 8080:8080/tcp \
+  -p 8080:8080/udp \
+  -v "${PWD}/config:/config" \
+  -v "${PWD}/data:/data" \
+  open-stage-control
+```
+
+Then open:
+
+`http://localhost:8080`
+
+## Docker Compose
+
+```bash
+docker compose up --build
+```
+
+## Gitea Actions
+
+The repo includes a Gitea Actions workflow at `.gitea/workflows/docker-publish.yml`.
+
+It will:
+
+- build on pushes to `main`
+- allow manual runs with `workflow_dispatch`
+- poll the upstream Open Stage Control releases API once a week
+- build and push a new image only when a new upstream release tag is found
+
+Required repository secrets:
+
+- `USER`: registry username
+- `TOKEN`: registry token or PAT for `git.f-40.com`
+
+## Environment Variables
+
+- `OSC_PORT`: HTTP port. Default `8080`.
+- `OSC_OSC_PORT`: OSC UDP input port. Default `8080`.
+- `OSC_TCP_PORT`: Optional OSC TCP input port.
+- `OSC_CACHE_DIR`: Config/cache path inside the container. Default `/config`.
+- `OSC_REMOTE_ROOT`: File browser root inside the container. Default `/data`.
+- `OSC_LOAD`: Optional session file to auto-load.
+- `OSC_STATE`: Optional state file to auto-load.
+- `OSC_CUSTOM_MODULE`: Optional custom module path.
+- `OSC_THEME`: Optional theme path or theme name.
+- `OSC_AUTHENTICATION`: Optional `user:password`.
+- `OSC_CLIENT_OPTIONS`: Optional single `key=value` client option. For multiple client options, pass extra CLI args after the image name.
+- `OSC_READ_ONLY`: Set to `true` to disable editing/saving.
+- `OSC_USE_SSL`: Set to `true` to enable HTTPS.
+- `OSC_DEBUG`: Set to `true` to log OSC traffic.
+- `OSC_NO_QRCODE`: Set to `true` to suppress QR output.
+
+## Extra CLI Arguments
+
+You can still pass native Open Stage Control arguments after the image name:
+
+```bash
+docker run --rm -p 8080:8080/tcp -p 8080:8080/udp open-stage-control --send 192.168.1.50:9000
+```
