    最終更新日:Sep 06, 2024

    kritis-validation-hook is a key component that is used to verify the signatures of container images. This topic describes the features, usage notes, and release notes for kritis-validation-hook.

    Introduction

    kritis-validation-hook is a key component that is used to verify the signatures of container images. You can use the signature verification feature to ensure that only images signed by trusted authorities are deployed. This reduces the risk of malicious code execution. For more information about kritis-validation-hook, see Introduction to kritis-validation-hook.

    Usage notes

    For more information about how to work with kritis-validation-hook, see Use kritis-validation-hook to automatically verify the signatures of container images.

    • If a container image fails to pass signature verification, a cluster event is generated in the kube-system namespace. The cause of the event is FailedKritisAdmission.

    • The dry run mode is supported. By default, this mode is disabled.

      If the dry run mode is enabled, container images that fail to pass signature verification can be deployed. If an image that fails to pass signature verification is deployed, a cluster event is generated in the kube-system namespace. The cause of the event is DryRunKritisAdmission.

    If exceptions occur when the system updates kritis-validation-hook, cluster resources may fail to be updated. We recommend that you update the component during off-peak hours.
