Constants

const KillGracePeriod = 10

killGracePeriod is the time in seconds after sending SIGTERM before forcefully killing the sidecar with SIGKILL (value matches k8s)

Functions

func CopyArchive

func CopyArchive(c KubernetesClientInterface, containerID, sourcePath, destPath string) error

CopyArchive downloads files and directories as a tarball and saves it to a specified path.

func GetContainerID

func GetContainerID(container *v1.ContainerStatus) string

GetContainerID returns container ID of a ContainerStatus resource

func KillGracefully

func KillGracefully(c KubernetesClientInterface, containerID string) error

KillGracefully kills a container gracefully.

func TerminatePodWithContainerID

func TerminatePodWithContainerID(c KubernetesClientInterface, containerID string, sig syscall.Signal) error

TerminatePodWithContainerID invoke the given SIG against the PID1 of the container. No-op if the container is on the hostPID

func WaitForTermination

func WaitForTermination(c KubernetesClientInterface, containerID string, timeout time.Duration) error

WaitForTermination of the given containerID, set the timeout to 0 to discard it

Types

type KubernetesClientInterface

type KubernetesClientInterface interface {
	GetContainerStatus(containerID string) (*v1.Pod, *v1.ContainerStatus, error)
	KillContainer(pod *v1.Pod, container *v1.ContainerStatus, sig syscall.Signal) error
	CreateArchive(containerID, sourcePath string) (*bytes.Buffer, error)
}

KubernetesClientInterface is the interface to implement getContainerStatus method
