Functions

func DumpToJSON 

func DumpToJSON(ctx context.Context, address string) ([]byte, error)

DumpToJSON dump to a json all information required to build a MockClient. It will dump from all namespace: containers and their task + PIDs.

Types

type ContainerOCISpec 

type ContainerOCISpec struct {
	containers.Container
	Spec *oci.Spec `json:"Spec,omitempty"`
}

ContainerOCISpec contains Info() & unmarshaled oci Spec.

type Containerd 

type Containerd struct {
	Addresses                 []string
	DeletedContainersCallback func(containersID []string)
	IsContainerIgnored        func(facts.Container) bool
	// contains filtered or unexported fields
}

Containerd implement connector to containerd.

func FakeContainerd 

func FakeContainerd(client *MockClient, isContainerIgnored func(facts.Container) bool) *Containerd

FakeContainerd return a Containerd runtime connector that use a mock client.

func New 

func New(
	runtime config.ContainerRuntimeAddresses,
	hostRoot string,
	deletedContainersCallback func(containersID []string),
	isContainerIgnored func(facts.Container) bool,
) *Containerd

New returns a new Docker runtime.

func (*Containerd) CachedContainer 

func (c *Containerd) CachedContainer(containerID string) (cont facts.Container, found bool)

CachedContainer return a container without querying ContainerD, it use in-memory cache which must have been filled by a call to Continers().

func (*Containerd) ContainerLastKill 

func (c *Containerd) ContainerLastKill(containerID string) time.Time

ContainerLastKill return the last time a container was killed or zero-time if unknown. containerd does not provide this information.

func (*Containerd) Events 

func (c *Containerd) Events() <-chan facts.ContainerEvent

Events return the channel used to send events. There is only one shared channel (so multiple consumer should be implemented by caller).

func (*Containerd) Exec 

func (c *Containerd) Exec(ctx context.Context, containerID string, cmd []string) ([]byte, error)

IsRuntimeRunning returns whether or not Containerd is available

IsRuntimeRunning will try to open a new connection if it never tried. It will also check that connection is still working (do a ping). Note: if ContainerD is running but Glouton can't access it, IsRuntimeRunning will return false.

func (*Containerd) Metrics 

func (c *Containerd) Metrics(ctx context.Context, now time.Time) ([]types.MetricPoint, error)

Metrics return metrics in a format similar to the one returned by Telegraf docker input. Note that Metrics will never open the connection to ContainerD and will return empty points if not connected.
