Kioskmanager

Do you have any screens in kiosk mode, any content managers which want to display websites and videos on your kiosk screens and do you want to empower them to do it by themselfes? Kioskmanager is the right app to do that.

Kioskmanager is a web application built with Django for managing and displaying digital content (videos, websites) on multiple screens or browsers, often referred to as kiosks or digital signage displays.

It provides a central admin interface to upload content, organize it into playlists assigned to specific display groups, and manage user access. Browsers connecting to the player endpoint are automatically identified and play the content loop assigned to their group.

Features

• Content Management: Upload videos and register website URLs via a web-based admin portal.
• Website Duration: Specify display duration for website content items.
• Display Groups: Create groups and assign ordered playlists of content (videos/websites) to them.
• Browser Identification: Player endpoints automatically identify connecting browsers using a persistent local identifier.
• Group Assignment: Assign identified browsers to specific Display Groups via the admin panel.
• Looping Playback: Player endpoint (/play/) automatically loops through the assigned group's playlist.
• Role-Based Access: Django admin with user management and permissions allowing non-superusers to manage content for specific groups.
• Persistent Media Storage: Uses Kubernetes Persistent Volumes to store uploaded video files.
• Database Backend: Utilizes PostgreSQL for storing application data.
• Helm Deployment: Includes a Helm chart for simplified deployment on Kubernetes.
• Video Caching: Nginx Ingress configuration snippet included for long-term caching of video assets.
• SSO: Login and manage users and groups using an OIDC provider. See

Getting Started

For detailed documentation for both administrators and end users, please visit Kioskmanager Documentation.

For deployment instructions, you can follow the steps outlined in this README.

Prerequisites for Deployment

• Kubernetes cluster (v1.19+ recommended).
• Helm v3.0+.
• Nginx Ingress Controller installed and configured in your cluster.
• A Persistent Volume (PV) provisioner available in your cluster (required if persistence.enabled is true, which is the default).

Installation using Helm

1. Add the Helm repo:

   helm repo add kioskmanager https://mbcom.github.io/kioskmanager/
   helm repo update

2. Configure Values:

   • Review and customize values.yaml for your environment.
   • Crucially, you need to set required values like the admin password (adminPassword), database password(s) (postgresql.auth.password or externalDatabase.password), and ingress host (ingress.hosts[0].host).
   • It is strongly recommended to manage sensitive values like passwords using --set flags during installation or dedicated Kubernetes secrets, rather than committing them directly to values.yaml.

3. Install the Chart:

   • Example using internal PostgreSQL:

     helm install kioskmanager kioskmanager/kioskmanager \
       --namespace <your-namespace> \
       --create-namespace \
       --set ingress.hosts[0].host=kioskmanager.yourdomain.com \
       --set adminPassword=<your-secure-admin-password> \
       --set postgresql.auth.password=<your-secure-db-password>

   • Example using external PostgreSQL:

     helm install kioskmanager kioskmanager/kioskmanager \
       --namespace <your-namespace> \
       --create-namespace \
       --set ingress.hosts[0].host=kioskmanager.yourdomain.com \
       --set adminPassword=<your-secure-admin-password> \
       --set postgresql.enabled=false \
       --set externalDatabase.host=<your-external-db-host> \
       --set externalDatabase.username=<your-external-db-user> \
       --set externalDatabase.password=<your-secure-external-db-password> \
       --set externalDatabase.database=<your-external-db-name>

4. Verify Deployment: Check the status of the pods, services, ingress, and persistent volume claims:

   kubectl get all -n <your-namespace>
   kubectl get pvc -n <your-namespace>
   kubectl logs deployment/<release-name>-kioskmanager -n <your-namespace> # Check application logs

Authentication

Kioskmanager supports two authentication methods for accessing the admin portal, configurable via the Helm chart (auth.method):

1. Standard Django Login: Uses Django's built-in username and password authentication.
2. OpenID Connect (OIDC): Allows integration with an external Identity Provider (IdP). When enabled, users can log in via the IdP, and their Django user accounts can be automatically created and updated based on OIDC claims, including group memberships.

Refer to the Admin Guide's authentication section and the Helm chart values for detailed OIDC configuration.

Development Guide

To set up the development environment for Kioskmanager, follow these steps:

Prerequisites:

• Python 3
• Node.JS 12 or above for using docs
• Git

1. Clone the Repository:

   git clone https://github.com/mbcom/kioskmanager.git
   cd kioskmanager

2. Set Environment Variables: Ensure the DJANGO_DEBUG environment variable is set to True for local development:

   export DJANGO_DEBUG=True

3. Install dependencies: Run the following command to install all dependencies:

   cd src
   pip install -r requirements.txt

4. Run migrations and create a superuser account: Run database migrations to initialize your local sqlite database:

   cd src
   python3 manage.py migrate

   Create a superadmin user. You need to do that only once:

   cd src
   python manage.py createsuperuser

5. Run the Application Locally: The application uses SQLite as the default database for local development. Start the Django development server:

   cd src
   python manage.py runserver

   You can now go to http://127.0.0.1:8000/ and login with credentials created in step 4.

6. Serve Documentation Locally: (optional) Navigate to the docs folder and run the following command to serve the documentation locally:

   cd docs
   npm run docs:dev

   The documentation will be available at http://localhost:5173/kioskmanager/.

Happy coding!
