Overview ¶
Package cadvisor provides an interface for Kubelet interactions with cAdvisor.
Index ¶
Constants ¶
const ( // CrioSocketSuffix is the path to the CRI-O socket. // Please keep this in sync with the one in: // github.com/google/cadvisor/tree/master/container/crio/client.go // Note that however we only match on the suffix, as /var/run is often a // symlink to /run, so the user can specify either path. CrioSocketSuffix = "run/crio/crio.sock" )

Functions ¶
func CapacityFromMachineInfo ¶ added in v1.2.0
func CapacityFromMachineInfo(info *cadvisorapi.MachineInfo) v1.ResourceList
CapacityFromMachineInfo returns the capacity of the resources from the machine info.
func EphemeralStorageCapacityFromFsInfo ¶ added in v1.8.0
func EphemeralStorageCapacityFromFsInfo(info cadvisorapi2.FsInfo) v1.ResourceList
EphemeralStorageCapacityFromFsInfo returns the capacity of the ephemeral storage from the FsInfo.
func UsingLegacyCadvisorStats ¶ added in v1.9.0
UsingLegacyCadvisorStats returns true if container stats are provided by cadvisor instead of through the CRI. CRI integrations should get container metrics via CRI. TODO: cri-o relies on cadvisor as a temporary workaround. The code should be removed. Related issue: https://github.com/kubernetes/kubernetes/issues/51798
Types ¶
type ImageFsInfoProvider ¶ added in v1.8.0
type ImageFsInfoProvider interface {
// ImageFsInfoLabel returns the label cAdvisor should use to find the filesystem holding container images.
ImageFsInfoLabel() (string, error)
// In split image filesystem this will be different from ImageFsInfoLabel
ContainerFsInfoLabel() (string, error)
}
ImageFsInfoProvider informs cAdvisor how to find imagefs for container images.
func NewImageFsInfoProvider ¶ added in v1.8.0
func NewImageFsInfoProvider(runtimeEndpoint string) ImageFsInfoProvider
NewImageFsInfoProvider returns a provider for the specified runtime configuration.
type Interface ¶
type Interface interface {
Start() error
ContainerInfoV2(name string, options cadvisorapiv2.RequestOptions) (map[string]cadvisorapiv2.ContainerInfo, error)
GetRequestedContainersInfo(containerName string, options cadvisorapiv2.RequestOptions) (map[string]*cadvisorapi.ContainerInfo, error)
MachineInfo() (*cadvisorapi.MachineInfo, error)
VersionInfo() (*cadvisorapi.VersionInfo, error)
// Returns usage information about the filesystem holding container images.
ImagesFsInfo() (cadvisorapiv2.FsInfo, error)
// Returns usage information about the root filesystem.
RootFsInfo() (cadvisorapiv2.FsInfo, error)
// Returns usage information about the writeable layer.
// KEP 4191 can separate the image filesystem
ContainerFsInfo() (cadvisorapiv2.FsInfo, error)
// Get filesystem information for the filesystem that contains the given file.
GetDirFsInfo(path string) (cadvisorapiv2.FsInfo, error)
}
Interface is an abstract interface for testability. It abstracts the interface to cAdvisor.
