Risks

Incorrect or inconsistent namespace management in Kubernetes can lead to several risks, such as exposing applications to the public internet, causing high downtime after cluster failures, and misallocating resources. Namespaces are designed to organize and isolate resources, especially in environments with multiple teams or projects. However, when namespaces are not properly configured or are overused to separate slightly different resources, it complicates cluster management and introduces security vulnerabilities.

Incorrect namespace configuration can result in resources broadcasting to unintended external networks, exposing sensitive data. Additionally, improper resource allocation across namespaces can cause inefficiencies and lead to downtime or application failures during cluster recovery.

To mitigate these risks, it is essential to manage namespaces correctly and ensure that roles and permissions are properly assigned.
