CDS

This is the CERN Document Server source code overlay.

Powered by Invenio

CDS is a small layer on top of Invenio, a ​free software suite enabling you to run your own ​digital library or document repository on the web.

Prerequisites

Ensure that the following dependencies are installed with the specified versions:

1. Python 3.9
2. Node.js v18
3. FFmpeg v5.0
4. Docker v2 or later: If Docker is not already installed, download and install Docker Desktop from the official Docker website.

Update dependencies

To update Python dependencies you need to run npm install in the target deployment environment:

$ docker run -it --platform="linux/amd64" --rm -v $(pwd):/app -w /app \
    registry.cern.ch/inveniosoftware/almalinux:1 \
    sh -c "dnf install -y openldap-devel && pip install -e . && pip freeze > requirements.new.txt"

Installation and Setup

1. Clone the Repository

Begin by cloning this repository and navigating to the project directory:

git clone https://github.com/CERNDocumentServer/cds-videos.git
cd cds-videos

2. Start Docker

Use Docker Compose to start the required containers in detached mode:

docker compose up -d

3. Run Setup Scripts

The scripts folder contains the necessary setup scripts to initialize and configure your instance.

1. Bootstrap Script

Initialize the environment by running the bootstrap script:

./scripts/bootstrap

Troubleshooting:

These are the macOS solutions using brew for installation.

If you encounter the error pg_config executable not found, you may need to install PostgreSQL and update the PATH:

brew install postgresql@14
export PATH=$PATH:/opt/homebrew/opt/postgresql@14/bin

For errors related to missing cmake and ninja tools ERROR: Command errored out with exit status 1 ... "cmake>=3.14" "ninja>=1.5":

Install cmake and ninja with the following command:

brew install cmake ninja

If you encounter errors with cryptography and OpenSSL, ensure that OpenSSL version 3 is installed:

brew install openssl@3

2. Setup Script

Run the setup script to finalize the installation and configuration:

./scripts/setup

Troubleshooting: If you encounter the error connection to server at "localhost", port 5432 failed: FATAL: role ".." does not exist, it may indicate an issue with the database role or a port conflict. To diagnose:

1. First, connect to the Docker database container and verify that the expected role exists and the database is working correctly.

   docker exec -it <db_container_name> psql -U <username> -d <database>

2. If the role is present and the database is functional, check for port conflicts on port 5432:

   lsof -i :5432

Terminate any conflicting process if found, and restart Docker.

4. Local Development

To facilitate local development, open multiple terminal sessions and run the following commands separately:

• Start Web Server This command launches the web server:

  ./scripts/server

• Start Celery Workers Celery workers are required for background task processing:

  ./scripts/celery

• Watch Frontend Code This command watches frontend code for changes and rebuilds assets as needed:

  ./scripts/assets-watch

Testing

Running the tests are as simple as:

python setup.py test

or (to also show test coverage)

source run-tests.sh
