   # Create a new stage for running the application that contains the minimal
   # runtime dependencies for the application. This often uses a different base
   # image from the build stage where the necessary files are copied from the build
   # stage.
   #
   # The example below uses the debian bullseye image as the foundation for    running the app.
   # By specifying the "bullseye-slim" tag, it will also use whatever happens to    be the
   # most recent version of that tag when you build your Dockerfile. If
   # reproducibility is important, consider using a digest
   # (e.g.,    debian@sha256:ac707220fbd7b67fc19b112cee8170b41a9e97f703f588b2cdbbcdcecdd8af57).
   FROM debian:bullseye-slim AS final

   # Create a non-privileged user that the app will run under.
   # See https://docs.docker.com/develop/develop-images/dockerfile_best-practices/   #user
   ARG UID=10001
   RUN adduser \
       --disabled-password \
       --gecos "" \
       --home "/nonexistent" \
       --shell "/sbin/nologin" \
       --no-create-home \
       --uid "${UID}" \
       appuser
   USER appuser

   # Copy the executable from the "build" stage.
   COPY --from=build /bin/server /bin/

   # Expose the port that the application listens on.
   EXPOSE 8000

   # What the container should run when it is started.
   CMD ["/bin/server"]
   ```

4. In the cloned repository's directory, run `docker build` to build the image.

   ```console
   $ docker build -t rust-backend-image .
   ```

5. Run `docker run` with the following options to run the image as a container on the same network as the database.

   ```console
   $ docker run \
     --rm -d \
     --network postgresnet \
     --name docker-develop-rust-container \
     -p 3001:8000 \
     -e PG_DBNAME=example \
     -e PG_HOST=db \
     -e PG_USER=postgres \
     -e PG_PASSWORD=mysecretpassword \
     -e ADDRESS=0.0.0.0:8000 \
     -e RUST_LOG=debug \
     rust-backend-image
   ```

6. Curl the application to verify that it connects to the database.

   ```console
   $ curl http://localhost:3001/users
   ```

   You should get a response like the following.

   ```json
   [{ "id": 1, "login": "root" }]
   ```

## Use Compose to develop locally

When you run `docker init`, in addition to a `Dockerfile`, it also creates a `compose.yaml` file.

This Compose file is super convenient as you don't have to type all the parameters to pass to the `docker run` command. You can declaratively do that using a Compose file.

In the cloned repository's directory, open the `compose.yaml` file in an IDE or text editor. `docker init` handled creating most of the instructions, but you'll need to update it for your unique application.

You need to update the following items in the `compose.yaml` file:

- Uncomment all of the database instructions.
- Add the environment variables under the server service.

The following is the updated `compose.yaml` file.

```yaml {hl_lines=["17-23","30-55"]}
# Comments are provided throughout this file to help you get started.
# If you need more help, visit the Docker compose reference guide at
# https://docs.docker.com/reference/compose-file/

# Here the instructions define your application as a service called "server".
