Functions

func ClusterDNSServiceIP

func ClusterDNSServiceIP() (string, error)

ClusterDNSServiceIP returns the cluster IP address of the DNS service. Attempts first to detect the DNS service on a k8s cluster and if not found on an openshift cluster.

func CreateCloudInitNetworkData

func CreateCloudInitNetworkData(networkData *CloudInitNetworkData) ([]byte, error)

CreateCloudInitNetworkData generates a configuration for the Cloud-Init Network Data version 2 format based on the inputed data.

func CreateDefaultCloudInitNetworkData

func CreateDefaultCloudInitNetworkData() (string, error)

CreateDefaultCloudInitNetworkData generates a default configuration for the Cloud-Init Network Data, in version 2 format. The default configuration sets dynamic IPv4 (DHCP) and static IPv6 addresses, inclusing DNS settings of the cluster nameserver IP and search domains.

func GetIp

func GetIp(ips []string, family k8sv1.IPFamily) string

func GetPodIpByFamily

func GetPodIpByFamily(pod *k8sv1.Pod, family k8sv1.IPFamily) string

func GetVmiPrimaryIpByFamily

func GetVmiPrimaryIpByFamily(vmi *v1.VirtualMachineInstance, family k8sv1.IPFamily) string

func IsClusterDualStack

func IsClusterDualStack(virtClient kubecli.KubevirtClient) (bool, error)

func PingFromVMConsole

func PingFromVMConsole(vmi *v1.VirtualMachineInstance, ipAddr string, args ...string) error

PingFromVMConsole performs a ping through the provided VMI console. Optional arguments for the ping command may be provided, overwirting the default ones. (default ping options: "-c 1, -w 5") Note: The maximum overall command timeout is 10 seconds.

func SearchDomains

func SearchDomains() []string

SearchDomains returns a list of default search name domains.

func SkipWhenNotDualStackCluster

func SkipWhenNotDualStackCluster(virtClient kubecli.KubevirtClient)

func ValidateVMIandPodIPMatch

func ValidateVMIandPodIPMatch(vmi *v1.VirtualMachineInstance, vmiPod *k8sv1.Pod) error

ValidateVMIandPodIPMatch Checks that the vmi pod and vmi scheme have matching Ip/Ips fields for primary interface
