Functions ¶

func GetAllLogs ¶

func GetAllLogs(log string) ([]string, error)

GetAllLogs gets all inuse (rotated/compressed) logs for a specific container log. Returned logs are sorted in oldest to newest order. TODO(#59902): Leverage this function to support log rotation in `kubectl logs`.

func UncompressLog ¶

func UncompressLog(log string) (_ io.ReadCloser, retErr error)

UncompressLog compresses a compressed log and return a readcloser for the stream of the uncompressed content. TODO(#59902): Leverage this function to support log rotation in `kubectl logs`.

Types ¶

type ContainerLogManager ¶

type ContainerLogManager interface {
	// TODO(random-liu): Add RotateLogs function and call it under disk pressure.
	// Start container log manager.
	Start()
}

ContainerLogManager manages lifecycle of all container logs.

Implementation is thread-safe.

func NewContainerLogManager ¶

func NewContainerLogManager(runtimeService internalapi.RuntimeService, maxSize string, maxFiles int) (ContainerLogManager, error)

NewContainerLogManager creates a new container log manager.

func NewStubContainerLogManager ¶

func NewStubContainerLogManager() ContainerLogManager

NewStubContainerLogManager returns an empty ContainerLogManager which does nothing.

type LogRotatePolicy ¶

type LogRotatePolicy struct {
	// MaxSize in bytes of the container log file before it is rotated. Negative
	// number means to disable container log rotation.
	MaxSize int64
	// MaxFiles is the maximum number of log files that can be present.
	// If rotating the logs creates excess files, the oldest file is removed.
	MaxFiles int
}

LogRotatePolicy is a policy for container log rotation. The policy applies to all containers managed by kubelet.
