+# Official `bknd` Docker image
+The docker image intentially doesn't copy any data into the image for now, so you can copy the
+Dockerfile and build the image anywhere.
+
+Locate the Dockerfile either by pulling the [repository](https://github.com/bknd-io/bknd) and navigating to the `docker`
+directory,
+or download from [here](https://github.com/bknd-io/bknd/blob/main/docker/Dockerfile).
+
+## Building the Docker image
+To build the Docker image, run the following command:
+
+```bash
+docker build -t bknd .
+```
+
+## Running the Docker container
+To run the Docker container, run the following command:
+
+```bash
+docker run -p 1337:1337 bknd
+```
+
+You can pass the same CLI arguments (see [Using the CLI](https://docs.bknd.io/cli) guide) to the
+docker container as you'd do with
+`npx bknd
+run`,
+like so:
+
+```bash
+docker run -p 1337:1337 -e ARGS="--db-url file:/data/data.db" bknd
+```
+Or connect to a remote turso database:
+```bash
+docker run -p 1337:1337 -e ARGS="--db-url libsql://<db>.turso.io --db-token <token>" bknd
+```
+
+To mount the data directory to the host, you can use the `-v` flag:
+```bash
+docker run -p 1337:1337 -v /path/to/data:/data bknd
+```
