(UBI) Policy not deleting correctly

Reporters

• Panagiotis Famelis (Ubitech)

Description

When deleting a policy through the PolicyService/PolicyDelete the policy is not correctly deleted in the Context component too. Additionally the Alarms in Monitoring component are not de-registered but continue to run.

This behavior means that the policy continues to run and is not deleted.

Deployment environment

• Operating System (include version): all
• MicroK8s (include version and add-ons): microk8s v1.24.
• TeraFlowSDN (include release/branch-name/commit-id): develop

TFS deployment settings

• list of components deployed: all cases
• particular configurations you applied: N/A
• any other particularity you might find important

Sequence of actions that resulted in the bug

• Create a policy tied to some specific KPI_id
• Delete the policy
• The policy continues to exist in the context component
• Alarms continue to raise in the monitoring component

Document the explicit error

• Check the web-ui, or call ContextPolicyService/ListPolicyRules to see that policy is still registered in context.
• Check the policyservice logs and you will see that alarms are still coming in

Expected behaviour

• When PolicyService/PolicyDelete, Policy component should stop receiving alarms (cancel the gRPC stream) and delete the specific policy from its db.
• The same should happen in Context component too.
