  • common API clients for internal communication
  • centralised OpenAPI specifications for REANA components
  • AMQP connection management and communication
  • utility functions for cluster components

  • Upgrades Kubernetes Python client.

Version 0.6.0 (2019-12-19)

  • Adds new API for Gitlab integration.
  • Adds new Kubernetes client API for ingresses.
  • Adds new APIs for management of user secrets.
  • Adds EOS storage Kubernetes configuration.
  • Adds HTCondor and Slurm compute backends.
  • Adds support for streaming file uploads.
