  • Kubernetes webhooks are used for setting default values and validating resources before they are stored into the Kubernetes API service.
  • Webhooks are considered a part of the Kubernetes control plane and are crucial for ensuring the stability of deployments.
  • If the operator isn't available, webhooks can potentially block deployments.
  • Customizing the operator's deployment can be done using a Helm chart.
  • Webhooks can be used to validate specific fields in Kubernetes resources.
