reana 0.6.1

About

REANA is a reusable and reproducible research data analysis platform. It helps researchers to structure their input data, analysis code, containerised environments and computational workflows so that the analysis can be instantiated and run on remote compute clouds.

REANA was born to target the use case of particle physics analyses, but is applicable to any scientific discipline. The system paves the way towards reusing and reinterpreting preserved data analyses even several years after the original publication.

Features

• structure research data analysis in reusable manner

• instantiate computational workflows on remote clouds

• rerun analyses with modified input data, parameters or code

• support for several compute clouds (Kubernetes/OpenStack)

• support for several workflow specifications (CWL, Serial, Yadage)

• support for several shared storage systems (Ceph)

• support for several container technologies (Docker)

  • See additional changes in reana-client 0.6.0 release notes.

• Administrators:

  • Upgrades to Kubernetes 1.16 and moves Traefik installation to Helm 3.0.0.

  • Creates a new Kubernetes service account for REANA with appropriate permissions.

  • Adds an interactive mode on cluster initialisation to allow providing deployment secrets.

  • Adds CERN specific Kerberos configuration files and CERN EOS storage support.

  • See additional changes in reana-cluster 0.6.0 release notes.

• Developers:

  • Modifies the batch workflow runtime pod creation including an instance of job controller running alongside workflow engine using the sidecar pattern.

  • Adds generic job manager class and provides example classes for CERN HTCondor and CERN Slurm clusters.

  • Provides user secrets to the job container runtime tasks.

  • Adds sidecar container to the Kubernetes job pod if Kerberos authentication is required.

  • Refactors job monitoring using the singleton pattern.

  • Enriches make behaviour for developer-oriented installations with live code reload changes and debugging.

  • Enriches git-status component status reporting for developers.
