# Deployment

The default username and password for Baby Buddy is `admin`/`admin`. For any
deployment, **log in and change the default password immediately**.

Many of Baby Buddy's configuration settings can be controlled using environment
variables - see [Configuration](../configuration/intro.md) for detailed information.

## Docker

Baby Buddy relies on the [LinuxServer.io](https://www.linuxserver.io/) community
for a multi-architecture container with strong support. See
[linuxserver/docker-babybuddy](https://github.com/linuxserver/docker-babybuddy)
for detailed information about the container or use the following Docker Compose
configuration as a template to get started quickly:

```yaml
version: "2.1"
services:
  babybuddy:
    image: lscr.io/linuxserver/babybuddy
    container_name: babybuddy
    environment:
      - TZ=UTC
    volumes:
      - /path/to/appdata:/config
    ports:
      - 8000:8000
    restart: unless-stopped
```

See [Django's databases documentation](https://docs.djangoproject.com/en/4.2/ref/databases/) for database requirements.

See [HTTPS/SSL configuration](ssl.md) for information on how to secure Baby Buddy.

### Running commands

Run administrative commands with the `/app/www/public/manage.py` script. Set
the environment variables `DJANGO_SETTINGS_MODULE` and `SECRET_KEY` before
running commands. For example:

```shell
docker exec -it babybuddy /bin/bash
export DJANGO_SETTINGS_MODULE="babybuddy.settings.base"
export SECRET_KEY="$(cat /config/.secretkey)"
cd /app/www/public
python manage.py --help
```

Note: the container name (`babybuddy`) and secret key location
(`/config/.secretkey`) may differ depending on the container configuration.
Refer to the running containers configuration for these values.

## Home Assistant

[Home Assistant](https://www.home-assistant.io/) is an open source home automation tool
that can be used to host and control Baby Buddy. An existing Home Assistant installation
is required to use this method.

See the community-maintained [Baby Buddy Home Assistant Addon](https://github.com/OttPeterR/addon-babybuddy)
for installation instructions and then review the community-maintained [Baby Buddy Home Assistant integration](https://github.com/jcgoette/baby_buddy_homeassistant)
for added integrations with the base Home Assistant system.

See also [How to Setup Baby Buddy in Home Assistant](https://smarthomescene.com/guides/how-to-setup-baby-buddy-in-home-assistant/)
from Smart Home Scene for more detailed installation and configuration instructions.

## Clever Cloud

To deploy on [Clever Cloud](https://www.clever-cloud.com), log in to your
[Clever Cloud console](https://console.clever-cloud.com/), create a Python
application, link it to a PostgreSQL addon and optionally a Cellar S3 Storage
addon (only if you want file storage for child picture in particular).
Then make sure to set the following environment variables in your Python
application before pushing the babybuddy source code:

```shell
CC_PYTHON_BACKEND=uwsgi
CC_PYTHON_MANAGE_TASKS=migrate
CC_PYTHON_MODULE=babybuddy.wsgi:application
DJANGO_SETTINGS_MODULE=babybuddy.settings.clever-cloud
SECRET_KEY=<CHANGE TO SOMETHING RANDOM>
TIME_ZONE=<DESIRED DEFAULT TIMEZONE>
AWS_STORAGE_BUCKET_NAME=<DESIRED BUCKET NAME> # only if file storage is needed
```

See [Configuration](../configuration/intro.md) for other environment variables available
for your instance of babybuddy.

After that, you just have to push babybuddy code repository to the Git
deployment URL of your Clever Cloud Python application.

## GCP Cloud Run

Baby Buddy can be hosted serverless in GCP Cloud Run using configuration provided at
`terraform/gcp-cloud-run`. The configuration scales down to zero for cost effectiveness.
With this approach initial requests to the service after a long period will be slow but
subsequent requests will be much faster. A [billing account](https://cloud.google.com/billing/docs/how-to/create-billing-account)
mut be configured in GCP to use the configuration.

The terraform code isn't production ready and is meant to be a good way of getting started.
No state strage is configured. See [storage options](https://cloud.google.com/run/docs/storage-options)
for information about how to configure persistant storage.

Run `terraform init` from the configurtion directory to get started:

```shell
git clone https://github.com/babybuddy/babybuddy.git
cd babybuddy/terraform/gcp-cloud-run
terraform init
terraform apply -var project_id=<project-id> -var project_name=<project-name> -var billing_account=<billing-account-id>
```

## Manual

There are many ways to deploy Baby Buddy manually to any server/VPS. The basic
requirements are Python, a web server, an application server, and a database.

### Requirements

- Python 3.10+, pip, pipenv
- Web server ([nginx](http://nginx.org/), [Apache](http://httpd.apache.org/), etc.)
- Application server ([uwsgi](http://projects.unbit.it/uwsgi), [gunicorn](http://gunicorn.org/), etc.)
- Database (See [Django's databases documentation](https://docs.djangoproject.com/en/4.2/ref/databases/)).

### Example deployment

*This example assumes a 1 GB VPS instance with Ubuntu 20.04.* It uses Python 3.10,
nginx, uwsgi and sqlite. It should be sufficient for a few users (e.g., two parents
and any number of children).

1. Install system packages

    ```shell
    sudo apt-get install python3 python3-pip nginx uwsgi uwsgi-plugin-python3 git libopenjp2-7-dev libpq-dev
    ```

2. Default python3 to python for this session

    ```shell
    alias python=python3
    ```

3. Install pipenv

    ```shell
    sudo -H pip3 install pipenv
    ```

4. Set up directories and files

    ```shell
    sudo mkdir /var/www/babybuddy
    sudo chown $USER:$(id -gn $USER) /var/www/babybuddy
    mkdir -p /var/www/babybuddy/data/media
    git clone https://github.com/babybuddy/babybuddy.git /var/www/babybuddy/public
    ```

5. Move in to the application folder

    ```shell
    cd /var/www/babybuddy/public
    ```

6. Initiate and enter a Python environment with Pipenv locally.

    ```shell
    export PIPENV_VENV_IN_PROJECT=1
    pipenv install --three
    pipenv shell
    ```

7. Create a production settings file and set the ``SECRET_KEY`` and ``ALLOWED_HOSTS`` values

    ```shell
    cp babybuddy/settings/production.example.py babybuddy/settings/production.py
    editor babybuddy/settings/production.py
    ```

8. Initiate the application

    ```shell
    export DJANGO_SETTINGS_MODULE=babybuddy.settings.production
    python manage.py migrate
    ```

9. Set appropriate permissions on the database and data folder

    ```shell
    sudo chown -R www-data:www-data /var/www/babybuddy/data
    sudo chmod 640 /var/www/babybuddy/data/db.sqlite3
    sudo chmod 750 /var/www/babybuddy/data
    ```

10. Create and configure the uwsgi app

    ```shell
    sudo editor /etc/uwsgi/apps-available/babybuddy.ini
    ```

    Example config:

    ```ini
    [uwsgi]
    plugins = python3
    project = babybuddy
    base_dir = /var/www/babybuddy

    chdir = %(base_dir)/public
    virtualenv = %(chdir)/.venv
    module =  %(project).wsgi:application
    env = DJANGO_SETTINGS_MODULE=%(project).settings.production
    master = True
    vacuum = True
    ```

    See the [uWSGI documentation](http://uwsgi-docs.readthedocs.io/en/latest/)
    for more advanced configuration details.

    See [Subdirectory configuration](subdirectory.md) for additional configuration
    required if Baby Buddy will be hosted in a subdirectory of another server.

11. Symlink config and restart uWSGI:

    ```shell
    sudo ln -s /etc/uwsgi/apps-available/babybuddy.ini /etc/uwsgi/apps-enabled/babybuddy.ini
    sudo service uwsgi restart
    ```

12. Create and configure the nginx server

    ```shell
    sudo editor /etc/nginx/sites-available/babybuddy
    ```

    Example config:

    ```nginx
    upstream babybuddy {
     server unix:///var/run/uwsgi/app/babybuddy/socket;
    }

    server {
     listen 80;
     server_name babybuddy.example.com;

     location / {
        uwsgi_pass babybuddy;
        include uwsgi_params;
     }

     location /media {
        alias /var/www/babybuddy/data/media;
     }
    }
    ```

    See the [nginx documentation](https://nginx.org/en/docs/) for more advanced
    configuration details.

    See [Subdirectory configuration](subdirectory.md) for additional configuration
    required if Baby Buddy will be hosted in a subdirectory of another server.

14. Symlink config and restart NGINX:

    ```shell
    sudo ln -s /etc/nginx/sites-available/babybuddy /etc/nginx/sites-enabled/babybuddy
    sudo service nginx restart
    ```

15. That's it (hopefully)!
