Description

There is an incompatibility issue when preparing development environment for TeraFlowSDN; in particular, components E2E Orch, VNTM, and NBI use websockets==12.0 while Device uses websockets==10.4. Upgrading to version 12.0 as features used in Device are compatible with that version also.

Deployment environment

  • Operating System (include version): any
  • MicroK8s (include version and add-ons): any
  • TeraFlowSDN (include release/branch-name/commit-id): develop
