Gatekeeper Disallow Default Namespace – Create, Deploy & Test Guide

1. 1Create a new Gatekeeper policy using the Rego language to define the rule for blocking workloads in the default namespace
2. 2Deploy the policy to your Kubernetes cluster using kubectl or another deployment tool
3. 3Test the policy by attempting to create a workload in the default namespace and verifying it is blocked
4. 4Configure the policy to allow exceptions for specific workloads or namespaces as needed
5. 5Validate the policy's effectiveness by running tests and checking for any potential issues or loopholes

DevOps engineers and Kubernetes administrators benefit from this guide to improve cluster security and organization, ensuring workloads are properly isolated and managed
