func ClearContainerHandlerFactories

func ClearContainerHandlerFactories()

Clear the known factories.

func DebugInfo

func DebugInfo() map[string][]string

func HasFactories

func HasFactories() bool

Returns whether there are any container handler factories registered.

func RegisterContainerHandlerFactory

func RegisterContainerHandlerFactory(factory ContainerHandlerFactory, watchTypes []watcher.ContainerWatchSource)

Register a ContainerHandlerFactory. These should be registered from least general to most general as they will be asked in order whether they can handle a particular container.


type ContainerHandler

type ContainerHandler interface {
	// Returns the ContainerReference
	ContainerReference() (info.ContainerReference, error)

	// Returns container's isolation spec.
	GetSpec() (info.ContainerSpec, error)

	// Returns the current stats values of the container.
	GetStats() (*info.ContainerStats, error)

	// Returns the subcontainers of this container.
	ListContainers(listType ListType) ([]info.ContainerReference, error)

	// Returns the processes inside this container.
	ListProcesses(listType ListType) ([]int, error)

	// Returns absolute cgroup path for the requested resource.
	GetCgroupPath(resource string) (string, error)

	// Returns container labels, if available.
	GetContainerLabels() map[string]string

	// Returns the container's ip address, if available
	GetContainerIPAddress() string

	// Returns whether the container still exists.
	Exists() bool

	// Cleanup frees up any resources being held like fds or go routines, etc.

	// Start starts any necessary background goroutines - must be cleaned up in Cleanup().
	// It is expected that most implementations will be a no-op.

	// Type of handler
	Type() ContainerType

Interface for container operation handlers.

func NewContainerHandler

func NewContainerHandler(name string, watchType watcher.ContainerWatchSource, inHostNamespace bool) (ContainerHandler, bool, error)

Create a new ContainerHandler for the specified container.

type ContainerHandlerFactory

type ContainerHandlerFactory interface {
	// Create a new ContainerHandler using this factory. CanHandleAndAccept() must have returned true.
	NewContainerHandler(name string, inHostNamespace bool) (c ContainerHandler, err error)

	// Returns whether this factory can handle and accept the specified container.
	CanHandleAndAccept(name string) (handle bool, accept bool, err error)

	// Name of the factory.
	String() string

	// Returns debugging information. Map of lines per category.
	DebugInfo() map[string][]string

type ContainerType int
const (
	ContainerTypeRaw ContainerType = iota

type ListType

type ListType int

ListType describes whether listing should be just for a specific container or performed recursively.

const (
	ListSelf ListType = iota

type MetricKind added in v0.22.0

type MetricKind string

MetricKind represents the kind of metrics that cAdvisor exposes.

	NetworkTcpUsageMetrics  MetricKind = "tcp"
	NetworkUdpUsageMetrics  MetricKind = "udp"
	AppMetrics              MetricKind = "app"

func (mk MetricKind) String() string

type MetricSet added in v0.22.0

type MetricSet map[MetricKind]struct{}

func (MetricSet) Add added in v0.22.0
