Top 10 use cases for Kyverno, Nirmata’s Kubernetes policy engine

Kyverno is an open-source Kubernetes policy engine that enables platform engineers to define, validate, and enforce policies for Kubernetes. It is a CNCF incubating project and is widely used by teams to protect their Kubernetes infrastructure. Based on the community usage of Kyverno,  we have compiled a list of the top 10 use cases for Kyverno:

  1. Security: Kyverno can be used to define security policies for Kubernetes resources to ensure that they meet specific security requirements, such as pod security, workload security, ensuring that sensitive data is encrypted, or limiting access to resources.
  2. Compliance: Kyverno can help organizations meet compliance requirements by ensuring that Kubernetes resources adhere to specific regulations or industry standards, such as HIPAA or PCI-DSS.
  3. Resource optimization: Kyverno can help optimize resource usage in Kubernetes environments by enforcing policies that limit resource consumption, such as CPU and memory usage. 
  4. Governance: Kyverno can help organizations enforce governance policies for Kubernetes resources, such as naming conventions or labeling requirements.
  5. Best practices: Kyverno can help enforce best practices for Kubernetes resources, such as ensuring that resources are properly configured and are using recommended Kubernetes constructs such as probes, storage classes, etc.
  6. Cost optimization: Kyverno can help optimize costs by enforcing policies that limit the creation of expensive resources, such as large persistent volumes, and also detecting and preventing the over-allocation of resources.
  7. Image verification: Kyverno can help ensure that only signed and attested images are deployed to clusters preventing possible software supply chain attacks.
  8. Data protection: Kyverno can help organizations ensure data protection policies for Kubernetes resources, such as ensuring that backup is enabled for critical data.
  9. Multi-tenancy: Kyverno can be used to automate the generation of required Kubernetes resources such as roles, role bindings, network policies, quotas, limits, etc whenever a new namespace is created.
  10. Automation: Kyverno can be used to automate common tasks in Kubernetes environments, such as creating and configuring resources, injecting CA certifications, scaling down failed deployments, and several more.

In summary, Kyverno is a flexible and powerful tool that can be used to address a wide range of use cases in Kubernetes environments, from security and compliance to resource optimization and automation. Kyverno’s declarative approach to policy management and native integration with Kubernetes makes it a popular choice for organizations looking to improve the reliability and security of their Kubernetes environments.
