Ensure that the --secure-port argument is not set to 0 (API Server)

Risk Level: High
Cloud Entity: Pods
CloudGuard Rule ID: D9.K8S.NET.08
Covered by Spectral: Yes
Category: Compute

GSL LOGIC

KubernetesPod where labels contain [value='kube-apiserver'] and namespace = 'kube-system' should have spec.containers with [(parsedArgs contain [key like 'secure-port' and value > 0]) or (parsedArgs contain-none [key like 'secure-port'])]

REMEDIATION

Edit the API server pod specification file $apiserverconf
on the master node and either remove the --secure-port parameter or
set it to a different (non-zero) desired port.

Pods

Pods are the smallest deployable units of computing that can be created and managed in Kubernetes. A Pod is a group of one or more containers (such as Docker containers), with shared storage/network, and a specification for how to run the containers.
