2.0.0

Known Issues

  • Secure container isolation for Storlets environment is still an ongoing work. Storlets enables user-defined code to run on the OpenStack Swift node with Docker container isolation level but a malicious user would run any attacking code there using recent vulnerability. Using more secure container like kata may mitigate such a risk of vulnerability.

  • Support user function written by py3 (current runner only supports python2 env)

Bug Fixes

  • Fix all python Storlets daemon processes as py3 compatible.

  • Switch test runner from testr to stestr

  • Other various minor bug fixes
