Functions

func GetConfigForDebug

func GetConfigForDebug() map[string]interface{}

GetConfigForDebug returns the active values of the configuration env vars (for debugging purposes).

func GetEthernetMTU(envMTUValue string) int

GetEthernetMTU gets the MTU setting from AWS_VPC_ENI_MTU if set, or takes the passed in string. Defaults to 9001 if not set.

func LinkByMac

func LinkByMac(mac string, netLink netlinkwrapper.NetLink, retryInterval time.Duration) (netlink.Link, error)

LinkByMac returns linux netlink based on interface MAC

Types

type NetworkAPIs

type NetworkAPIs interface {
	// SetupNodeNetwork performs node level network configuration
	SetupHostNetwork(vpcCIDR *net.IPNet, vpcCIDRs []*string, primaryMAC string, primaryAddr *net.IP) error
	// SetupENINetwork performs eni level network configuration
	SetupENINetwork(eniIP string, mac string, table int, subnetCIDR string) error

	UpdateRuleListBySrc(ruleList []netlink.Rule, src net.IPNet, toCIDRs []string, toFlag bool) error
	DeleteRuleListBySrc(src net.IPNet) error
}

NetworkAPIs defines the host level and the ENI level network related operations

func New

func New() NetworkAPIs

New creates a linuxNetwork object
