Types

type AntreaIPAM

type AntreaIPAM struct {
	// contains filtered or unexported fields
}

Antrea IPAM driver would allocate IP addresses according to object IPAM annotation, if present. If annotation is not present, the driver will delegate functionality to traditional IPAM driver.

func (*AntreaIPAM) Add

func (d *AntreaIPAM) Add(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, *IPAMResult, error)

Add allocates next available IP address from associated IP Pool Allocated IP and associated resource are stored in IP Pool status

func (*AntreaIPAM) Check

func (d *AntreaIPAM) Check(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, error)

Check verifues IP associated with resource is tracked in IP Pool status

func (*AntreaIPAM) Del

func (d *AntreaIPAM) Del(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, error)

Del deletes IP associated with resource from IP Pool status

type AntreaIPAMController

type AntreaIPAMController struct {
	// contains filtered or unexported fields
}

Antrea IPAM Controller maintains map of Namespace annotations using Namespace informer. In future, which Antrea IPAM support expands, this controller can be used to store annotations for other objects, such as Statefulsets.

func InitializeAntreaIPAMController

func InitializeAntreaIPAMController(crdClient clientsetversioned.Interface,
	informerFactory informers.SharedInformerFactory,
	crdInformerFactory externalversions.SharedInformerFactory,
	podInformer cache.SharedIndexInformer, ipamAnnotations bool) (*AntreaIPAMController, error)

func (*AntreaIPAMController) Run

func (c *AntreaIPAMController) Run(stopCh <-chan struct{})

Run starts to watch and process Namespace updates for the Node where Antrea Agent is running, and maintain a mapping between Namespace name and IPAM annotations.

type IPAMDelegator

type IPAMDelegator struct {
	// contains filtered or unexported fields
}

func (*IPAMDelegator) Add

func (d *IPAMDelegator) Add(args *invoke.Args, k8sArgs *argtypes.K8sArgs, networkConfig []byte) (bool, *IPAMResult, error)

func (*IPAMDelegator) Check

func (d *IPAMDelegator) Check(args *invoke.Args, k8sArgs *argtypes.K8sArgs, networkConfig []byte) (bool, error)

func (*IPAMDelegator) Del

func (d *IPAMDelegator) Del(args *invoke.Args, k8sArgs *argtypes.K8sArgs, networkConfig []byte) (bool, error)

type IPAMDriver

type IPAMDriver interface {
	Add(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, *IPAMResult, error)
	Del(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, error)
	Check(args *invoke.Args, k8sArgs *types.K8sArgs, networkConfig []byte) (bool, error)
}

type IPAMResult

type IPAMResult struct {
	current.Result
	VLANID uint16
}

func ExecIPAMAdd
