Functions ¶

func DetectClusterDomain ¶

func DetectClusterDomain() (string, bool)

DetectClusterDomain attempts to detect the Kubernetes cluster domain from /etc/resolv.conf search domains.

It looks for a search domain matching the pattern "*.svc.<domain>" and extracts the cluster domain suffix.

Returns the detected domain and true if successful, or empty string and false if detection failed.

func DetectClusterDomainFromFile ¶

func DetectClusterDomainFromFile(path string) (string, bool)

DetectClusterDomainFromFile reads resolv.conf from a given path and extracts the cluster domain from search domains. Exported for testing purposes.
