kyverno/CHANGELOG.md

v1.8.1-rc3

Note

• A new flag backgroundScanWorkers to configure the number of background scan workers (default value is 2).

v1.8.0-rc3

Note

• A new flag backgroundScan to enable/disable kyverno background scans (default value is true). When this is set to false, kyverno will not perform background scans and won't trigger continuous evaluation of policies.
• A new flag admissionReports to enable/disable kyverno admission reports (default value is true). When this is set to false, kyverno will not create admission reports.
• If both backgroundScan and admissionReports are set to false the entire reports system will be disabled.
• A new flag reportsChunkSize to split reports according to the number of results contained in the report (default value is 1000). This can be disabled by setting the flag value to 0.
• Deprecated splitPolicyReport flag, splitting reports per policy is always enabled, keeping it for backward compatibility, will be removed in future version.
• ReportChangeRequest and ClusterReportChangeRequest CRDs have been removed and replaced by AdmissionReport, ClusterAdmissionReport, BackgroundScanReport and ClusterBackgroundScanReport CRDs.

v1.8.0-rc1

Note

• A new flag protectManagedResources to enable kyverno managed resources protection (default value is false). When this is enabled, kyverno managed resources can only be modified or deleted by the controller.

v1.7.2-rc2

Note

• A new flag maxQueuedEvents is added to the Kyverno main container, this flag sets the up-limit of the events that are queued internally.

v1.7.2-rc1

Note

• A new flag maxReportChangeRequests is added to the Kyverno main container, this flag sets the up-limit of reportchangerequests that a namespace can take, or clusterreportchangerequests if matching kinds are cluster-wide resources. The default limit is set to 1000, and it's recommended to configure it to a small threshold on large clusters. Here the large clusters are considered that a policy report has more than 1k results.

v1.7.0-rc1

Note

• status.ready of the policy is deprecated in favor of policy.IsReady(). The implementation was changed to use status.conditions that offer more flexibility. The status.ready will be kept for a couple of releases until we remove it in the future.
• Deprecated flags have been removed.
• Flags that were overlapping with config map based configuration were removed (filterK8sResources, excludeGroupRole, excludeUsername). They can now be configured using the config map only.

v1.6.0-rc1

Note

• Helm charts are changed to enforce PodDisruptionBudget for multi-replica clusters and PDB is removed from install manifests.
• anyPattern for Kyverno validate policies breaks in Kubernetes v1.23.0-v1.23.2, and the fix is being tracked by this PR and will be available in v1.23.3.
• To use any/all conditions for policies that use preconditons and deny.conditions, the user can go to this resource as a good starting point.

v1.5.0-rc1

Note

• The Helm CRDs was switched back to kyverno chart. To upgrade using Helm, please refer to https://github.com/kyverno/website/pull/304.
• With the change of dynamic webhooks, the readiness of the policy is reflected by .status.ready, When ready, it means the policy is ready to serve the admission requests.

Deprecation

• To add a consistent style in flag names the following flags have been deprecated webhooktimeout, gen-workers,disable-metrics, background-scan, auto-update-webhooks, profile-port, metrics-port these will be removed in 1.6.0. The new flags are webhookTimeout, genWorkers, disableMetrics, backgroundScan, autoUpdateWebhooks,profilePort, metricsPort (#1991).
