Variables ¶
ErrUnknownPod is an error when there is no pod in data store matching pod name, namespace, container id
ErrUnknownPodIP is an error where pod's IP address is not found in data store
Functions ¶
This section is empty.
Types ¶
type AddressInfo ¶
type AddressInfo struct { Assigned bool // true if it is assigned to a pod // contains filtered or unexported fields }
AddressInfo contains information about an IP, Exported fields will be marshaled for introspection.
type DataStore ¶
type DataStore struct {
// contains filtered or unexported fields
}
DataStore contains node level ENI/IP
func (*DataStore) AddENI ¶
AddENI add ENI to data store
func (*DataStore) AddENIIPv4Address ¶
AddENIIPv4Address add an IP of an ENI to data store
func (*DataStore) AssignPodIPv4Address ¶
AssignPodIPv4Address assigns an IPv4 address to pod It returns the assigned IPv4 address, device number, error
func (*DataStore) DelENIIPv4Address ¶
DelENIIPv4Address delete an IP of ENI from datastore
func (*DataStore) DeleteENI ¶
DeleteENI free a ENI.
func (*DataStore) FreeENI ¶
FreeENI frees a deletable ENI. It returns the name of the ENI which is deleted out the data store
func (*DataStore) GetENIIPPools ¶
func (ds *DataStore) GetENIIPPools(eni string) (map[string]*AddressInfo, error)
GetENIIPPools returns eni's IP address list
func (*DataStore) GetENIInfos ¶
GetENIInfos provides ENI IP information to introspection endpoint
func (*DataStore) GetENINeedsIP ¶
GetENINeedsIP finds out the eni in datastore which failed to get secondary IP address
func (*DataStore) GetENIs ¶
GetENIs provides the number of ENI in the datastore
func (*DataStore) GetPodInfos ¶
GetPodInfos provides pod IP information to introspection endpoint
func (*DataStore) GetStats ¶
GetStats returns statistics it returns total number of IP addresses, number of assigned IP addresses
func (*DataStore) UnAssignPodIPv4Address ¶
UnAssignPodIPv4Address a) find out the IP address based on PodName and PodNameSpace b) mark IP address as unassigned c) returns IP address, ENI's device number, error
type ENIIPPool ¶
type ENIIPPool struct { // IsPrimary indicates whether ENI is a primary ENI IsPrimary bool ID string // DeviceNumber is the device number of ENI DeviceNumber int // AssignedIPv4Addresses is the number of IP addresses already been assigned AssignedIPv4Addresses int // IPv4Addresses shows whether each address is assigned, the key is IP address, which must // be in dot-decimal notation with no leading zeros and no whitespace(eg: "10.1.0.253") IPv4Addresses map[string]*AddressInfo // contains filtered or unexported fields }
ENIIPPool contains ENI/IP Pool information. Exported fields will be marshaled for introspection.
type ENIInfos ¶
type ENIInfos struct { // TotalIPs is the total number of IP addresses TotalIPs int // assigned is the number of IP addresses that has been assigned AssignedIPs int // ENIIPPools contains ENI IP pool information ENIIPPools map[string]ENIIPPool }
ENIInfos contains ENI IP information
type PodIPInfo ¶
type PodIPInfo struct { // IP is the IP address of pod IP string // DeviceNumber is the device number of pod DeviceNumber int }
PodIPInfo contains pod's IP and the device number of the ENI
type PodInfos ¶
PodInfos contains pods IP information which uses key name_namespace_container
type PodKey ¶
type PodKey struct {
// contains filtered or unexported fields
}
PodKey is used to locate pod IP
