Test coverage
Tested manually with an existing node, using existing policy:
$ k create -f node-cp-2.yml
Error from server: error when creating "node-cp-2.yml": admission webhook "validate.kyverno.svc-fail" denied the request:
resource Node//management-cluster-management-cp-2 was blocked due to the following policies
prevent-node-provider-id-reuse:
prevent-node-provider-id-reuse: Check if node providerID has already been used;
Blocking node creation as there was already a node with providerID management-cluster-cp-f8e612ae8d-q5987
With proposed change:
$ k create -f node-cp-2.yml
Error from server (AlreadyExists): error when creating "node-cp-2.yml": nodes "management-cluster-management-cp-2" already exists

Global config for deployment pipelines
-
autorun pipelines -
allow failure on pipelines -
record sylvactl events
Notes:
- Enabling
autorunwill make deployment pipelines to be run automatically without human interaction - Disabling
allow failurewill make deployment pipelines mandatory for pipeline success. - if both
autorunandallow failureare disabled, deployment pipelines will need manual triggering but will be blocking the pipeline
Be aware: after configuration change, pipeline is not triggered automatically.
Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
