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

For doing administrative work within the LSIO container, setting an environment variable may be necessary.
For example:

```shell
docker exec -it babybuddy /bin/bash
export DJANGO_SETTINGS_MODULE="babybuddy.settings.base"
python3 /app/babybuddy/manage.py clearsessions
```

## 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, createcachetable
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.

## 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 3.7+, 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 ([sqlite](https://sqlite.org/), [Postgres](https://www.postgresql.org/), [MySQL](https://www.mysql.com/), etc.)

### Example deployment

*This example assumes a 1 GB VPS instance with Ubuntu 20.04.* It uses Python 3.8,
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
    python manage.py createcachetable
    ```

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)!
