Welcome to the Curious Containers project and its RED file format for reproducible experiments.

Computational Reproducibility

RED (Reproducible Experiment Description) is a JSON or YAML based file format to describe data-driven experiments. A RED file allows researchers to share or publish their computational experiments, such that others can reproduce the results or customize the experiments. A minimal RED file consists of an application’s commandline interface (CLI) description in Common Workflow Language (CWL) syntax, as well as CLI arguments and input file references.

Curious Containers provides a reference implementation of RED in Python (cc-core). Experiments can be executed on a local Linux host using the Docker container runtime via the FAICE tool suite (cc-faice). For a more advanced usage, Curious Containers Agency (cc-agency) can distribute experiments in a Docker cluster across multiple hosts.

Together, RED and Curious Containers support the FAIR principles for reproducible research. If you are new to the project, we advise you to work through the RED Beginner’s Guide. Examples can be found on the Tawian meta-platform.

Machine Learning Workloads

We are improving CC’s capablities in the realm of machine learning and other high performance workloads. CC ships with support for CUDA via nvidia-docker. Large data directories (e.g. CAMELYON image database) can be mounted via FUSE based network connectors.


The Curious Containers software is developed at CBMI (HTW Berlin - University of Applied Sciences). The work is supported by the German Federal Ministry of Economic Affairs and Energy (ZIM project BeCRF, grant number KF3470401BZ4), the German Federal Ministry of Education and Research (project deep.TEACHING, grant number 01IS17056 and project deep.HEALTH, grant number 13FH770IX6) and HTW Berlin Booster.
