Nextflow Cloud or NF-Cloud is a web interface to run nextflow workflows in a cloud environment.
NF-Cloud has three compontents

A web API written in Flask for managing/scheduling workflows.

A web interface written in NuxtJS. This is basically a GUI for the web interface.

A worker witten in python which runs the scheduled workflows.

Make sure the dependencies in

• Frontend
• Backend
• Worker

are installed.

# Create environment
pipenv shell

# Upgrade pip and setuptools
pip install --upgrade pip setuptools

# Install dependencies
pipenv install -d

# Install node requirements
yarn --cwd ./nf_cloud_frontend install

# Shell 1
docker-compose up
# Shell 2
pipenv run db:migrate 'postgresql://postgres:developer@127.0.0.1:5434/nf_cloud'
pipenv run dev

For development, Flask is configured to add CORS-Headers by default.

To keep track of database changes, this project uses peewee_migrate. Migrations are located in nf_cloud_backend/migrations/. For now this needs to be added manually when using pw_migrate.

Still work in progress.

Set the consumer_timeout to a high value. Otherwise scheduled workflows can't be acknowledged after finishing and getting rescheduled.

• Try to move Nextflow intermediate result folders into a subfolder.
• Add some more inputs
  • Radio
  • Select
• Add description to workflows
• Improve logging
  • Save Nextflow stdout/stderr
  • Enable report and show resulting HTML in web interface
• Rework docker deployment
  • Investigate if the worker is able to run Nextflow in Docker containers when running in container itself
