Functions

func GetAppType(appTypePrefix string) string

GetAppType formats appTypePrefix to appType

func GetAppTypePrefix

func GetAppTypePrefix(kind string) string

GetAppTypePrefix formats an appTypePrefix for the given resource kind

func Join

func Join(name, namespace string) string

func PodName

func PodName(pod *corev1.Pod) string

Types

type KeyObj

type KeyObj struct {
	// stores the key format in IPAM
	// for deployment dp_namespace_deploymentName_podName,
	// for pool pool__poolName_dp_namespace_deploymentName_podName, for statefulset
	// sts_namespace_statefulsetName_podName
	// If deployment name is 63 bytes, e.g. dp1234567890dp1234567890dp1234567890dp1234567890dp1234567890dp1
	// deployment pod name will be 63 bytes with modified suffix, e.g.
	// dp1234567890dp1234567890dp1234567890dp1234567890dp1234567848p74
	// So we can't get deployment name from pod name and have to store deployment name with pod name
	KeyInDB       string
	AppName       string
	AppTypePrefix string
	PodName       string
	Namespace     string
	// the annotation value if pod has pool annotation
	PoolName string
}

func FormatKey

func FormatKey(pod *corev1.Pod) (*KeyObj, error)

func NewKeyObj

func NewKeyObj(appTypePrefix string, namespace, appName, podName, poolName string) *KeyObj

func ParseKey

func ParseKey(key string) *KeyObj

func (*KeyObj) Deployment

func (k *KeyObj) Deployment() bool

func (*KeyObj) PoolAppPrefix

func (k *KeyObj) PoolAppPrefix() string

func (*KeyObj) PoolPrefix

func (k *KeyObj) PoolPrefix() string

PoolPrefix returns the common key prefix in IPAM, for deployment dp_namespace_deploymentName_ for pool pool__poolName_, for statefulset sts_namespace_statefulsetName_ For now, if it is a statefulset pod, PoolPrefix is useless since we reserve ip by full pod name PoolPrefix is used by pool and deployment only.

func (*KeyObj) StatefulSet

func (k *KeyObj) StatefulSet() bool
