Types

type Container

type Container struct {
	Inspector Inspector

	Display      string // Friendly Name
	Name         string // container name
	ID           string // container sha/id
	Digest       string // Container Digest
	Image        string
	PodName      string
	Sandbox      string
	Status       string // Running state of container
	RestartCount string
	LogPath      string
	Metrics      *ContainerMetrics
	Pid          uint32
	IsPodSandbox bool // real container or just pod sandbox
}

Container presents information about a container.

func (*Container) GetLogChunker

func (c *Container) GetLogChunker(ctx context.Context, follow bool, tailLines int) (chunker.Chunker, io.Closer, error)

GetLogChunker returns chunker for container log file.

func (*Container) GetLogFile

func (c *Container) GetLogFile() string

GetLogFile returns path to log file, k8s-style.

func (*Container) GetProcessStderr

func (c *Container) GetProcessStderr() (string, error)

GetProcessStderr returns process stderr.

func (*Container) Kill

func (c *Container) Kill(signal syscall.Signal) error

Kill sends signal to container task.

type ContainerMetrics

type ContainerMetrics struct {
	MemoryUsage uint64
	CPUUsage    uint64
}

ContainerMetrics represents container cgroup stats.

type Inspector

type Inspector interface {
	// Pods collects information about running pods & containers.
	Pods() ([]*Pod, error)
	// Container returns info about a single container.
	Container(id string) (*Container, error)
	// Close frees associated resources.
	Close() error
	// Returns path to the container's stderr pipe
	GetProcessStderr(ID string) (string, error)
	// Kill sends signal to container's process
	Kill(ID string, isPodSandbox bool, signal syscall.Signal) error
}

Inspector gather information about pods & containers.

type Pod

type Pod struct {
	Name    string
	Sandbox string

	Containers []*Container
}

Pod presents information about a pod, including a list of containers.
