Polaris – Validation Of Best Practices In Your Kubernetes Clusters

Polaris is an open source policy engine for Kubernetes

Polaris is an open source policy engine for Kubernetes that validates and remediates resource configuration. It includes 30+ built in configuration policies, as well as the ability to build custom policies with JSON Schema. When run on the command line or as a mutating webhook, Polaris can automatically remediate issues based on policy criteria.

Polaris can be run in three different modes:

  • As a dashboard – Validate Kubernetes resources against policy-as-code.
  • As an admission controller – Automatically reject or modify workloads that don’t adhere to your organization’s policies.
  • As a command-line tool – Incorporate policy-as-code into the CI/CD process to test local YAML files.
