Functions

func ConstructEndpointID

func ConstructEndpointID(containerID string, netNsPath string, ifName string) (string, string)

ConstructEndpointID constructs endpoint name from netNsPath.

Types

type DNSInfo

type DNSInfo struct {
	Suffix  string
	Servers []string
}

DNSInfo contains DNS information for a container network or endpoint.

type EndpointInfo

type EndpointInfo struct {
	Id          string
	ContainerID string
	NetNsPath   string
	IfName      string
	IPAddresses []net.IPNet
	Routes      []RouteInfo
	DNS         DNSInfo
	Policies    []policy.Policy
	Data        map[string]interface{}
}

EndpointInfo contains read-only information about an endpoint.

type Namespace

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

Namespace represents a network namespace.

func GetCurrentThreadNamespace

func GetCurrentThreadNamespace() (*Namespace, error)

GetCurrentThreadNamespace returns the caller thread's current namespace.

func OpenNamespace

func OpenNamespace(nsPath string) (*Namespace, error)

OpenNamespace creates a new namespace object for the given netns path.

func (*Namespace) Close

func (ns *Namespace) Close() error

Close releases the resources associated with the namespace object.

func (*Namespace) Enter

func (ns *Namespace) Enter() error

Enter puts the caller thread inside the namespace.

func (*Namespace) Exit

func (ns *Namespace) Exit() error

Exit puts the caller thread to its previous namespace.

func (*Namespace) GetFd

func (ns *Namespace) GetFd() uintptr

GetFd returns the file descriptor of the namespace.

type NetworkInfo

type NetworkInfo struct {
	Id         string
	Mode       string
	Subnets    []SubnetInfo
	DNS        DNSInfo
	Policies   []policy.Policy
	BridgeName string
	Options    map[string]interface{}
}

NetworkInfo contains read-only information about a container network.
