Apache Druid provides a custom Jupyter container that contains the prerequisites
for all Jupyter-based Druid tutorials, as well as all of the tutorials themselves.
You can run the Jupyter container, as well as containers for Druid and Apache Kafka,
using the Docker Compose file provided in the Druid GitHub repository.

You can run the following combination of applications:
* [Jupyter only](#start-only-the-jupyter-container)
* [Jupyter and Druid](#start-jupyter-and-druid)
* [Jupyter, Druid, and Kafka](#start-jupyter-druid-and-kafka)

## Prerequisites

Jupyter in Docker requires that you have **Docker** and **Docker Compose**.
We recommend installing these through [Docker Desktop](https://docs.docker.com/desktop/).

## Launch the Docker containers

You run Docker Compose to launch Jupyter and optionally Druid or Kafka.
Docker Compose references the configuration in `docker-compose.yaml`.
Running Druid in Docker also requires the `environment` file, which
sets the configuration properties for the Druid services.
To get started, download both `docker-compose.yaml` and `environment` from
[`tutorial-jupyter-docker.zip`](https://github.com/apache/druid/blob/master/examples/quickstart/jupyter-notebooks/docker-jupyter/tutorial-jupyter-docker.zip).

Alternatively, you can clone the [Apache Druid repo](https://github.com/apache/druid) and
access the files in `druid/examples/quickstart/jupyter-notebooks/docker-jupyter`.

### Start only the Jupyter container

If you already have Druid running locally, you can run only the Jupyter container to complete the tutorials.
In the same directory as `docker-compose.yaml`, start the application:

```bash
docker compose --profile jupyter up -d
```

The Docker Compose file assigns `8889` for the Jupyter port.
You can override the port number by setting the `JUPYTER_PORT` environment variable before starting the Docker application.

### Start Jupyter and Druid

Running Druid in Docker requires the `environment` file as well as an environment variable named `DRUID_VERSION`,
which determines the version of Druid to use. The Druid version references the Docker tag to pull from the
[Apache Druid Docker Hub](https://hub.docker.com/r/apache/druid/tags).

In the same directory as `docker-compose.yaml` and `environment`, start the application:

```bash
DRUID_VERSION={{DRUIDVERSION}} docker compose --profile druid-jupyter up -d
```

### Start Jupyter, Druid, and Kafka

Running Druid in Docker requires the `environment` file as well as the `DRUID_VERSION` environment variable.

In the same directory as `docker-compose.yaml` and `environment`, start the application:

```bash
DRUID_VERSION={{DRUIDVERSION}} docker compose --profile all-services up -d
```

### Update image from Docker Hub

If you already have a local cache of the Jupyter image, you can update the image before running the application using the following command:

```bash
docker compose pull jupyter
```

### Use locally built image

The default Docker Compose file pulls the custom Jupyter Notebook image from a third party Docker Hub.
If you prefer to build the image locally from the official source, do the following:
1. Clone the Apache Druid repository.
2. Navigate to `examples/quickstart/jupyter-notebooks/docker-jupyter`.
3. Start the services using `-f docker-compose-local.yaml` in the `docker compose` command. For example:

```bash
DRUID_VERSION={{DRUIDVERSION}} docker compose --profile all-services -f docker-compose-local.yaml up -d
```

## Access Jupyter-based tutorials

The following steps show you how to access the Jupyter notebook tutorials from the Docker container.
At startup, Docker creates and mounts a volume to persist data from the container to your local machine.
This way you can save your work completed within the Docker container.

1. Navigate to the notebooks at http://localhost:8889.
   > If you set `JUPYTER_PORT` to another port number, replace `8889` with the value of the Jupyter port.

2. Select a tutorial. If you don't plan to save your changes, you can use the notebook directly as is. Otherwise, continue to the next step.

3. Optional: To save a local copy of your tutorial work,
select **File > Save as...** from the navigation menu. Then enter `work/<notebook name>.ipynb`.
If the notebook still displays as read only, you may need to refresh the page in your browser.
Access the saved files in the `notebooks` folder in your local working directory.

## View the Druid web console

To access the Druid web console in Docker, go to http://localhost:8888/unified-console.html.
Use the web console to view datasources and ingestion tasks that you create in the tutorials.

## Stop Docker containers

Shut down the Docker application using the following command:

```bash
docker compose down -v
```

## Tutorial setup without using Docker

To use the Jupyter Notebook-based tutorials without using Docker, do the following:

1. Clone the Apache Druid repo, or download the [tutorials](tutorial-jupyter-index.md#tutorials)
as well as the [Python client for Druid](tutorial-jupyter-index.md#python-api-for-druid).

2. Install the prerequisite Python packages with the following commands:

   ```bash
   # Install requests
   pip install requests
   ```

   ```bash
   # Install JupyterLab
   pip install jupyterlab
   
   # Install Jupyter Notebook
   pip install notebook
   ```

   Individual notebooks may list additional packages you need to install to complete the tutorial.

3. In your Druid source repo, install `druidapi` with the following commands:

   ```bash
   cd examples/quickstart/jupyter-notebooks/druidapi
   pip install .
   ```

4. Start Jupyter, in the same directory as the tutorials, using either JupyterLab or Jupyter Notebook:
   ```bash
   # Start JupyterLab on port 3001
   jupyter lab --port 3001

   # Start Jupyter Notebook on port 3001
   jupyter notebook --port 3001
   ```

5. Start Druid. You can use the [Quickstart (local)](./index.md) instance. The tutorials
   assume that you are using the quickstart, so no authentication or authorization
   is expected unless explicitly mentioned.

   If you contribute to Druid, and work with Druid integration tests, you can use a test cluster.
   Assume you have an environment variable, `DRUID_DEV`, which identifies your Druid source repo.
 
   ```bash
   cd $DRUID_DEV
   ./it.sh build
   ./it.sh image
   ./it.sh up <category>
   ```
 
   Replace `<category>` with one of the available integration test categories. See the integration
   test `README.md` for details.

You should now be able to access and complete the tutorials.
