Overview ¶
Unmarshal's a Containers description json file. The json file contains an array of ContainerHint structs, each with a container's id and networkInterface This allows collecting stats about network interfaces configured outside docker and lxc
Handler for Docker containers.

Functions ¶
func AssignDeviceNamesToDiskStats ¶ added in v0.26.0
func AssignDeviceNamesToDiskStats(namer DeviceNamer, stats *info.DiskIoStats)
AssignDeviceNamesToDiskStats assigns the Device field on the provided DiskIoStats by looking up the device major and minor identifiers in the provided device namer.
func CgroupExists ¶
func GetControllerPath ¶ added in v0.44.0
func GetSpec ¶
func GetSpec(cgroupPaths map[string]string, machineInfoFactory info.MachineInfoFactory, hasNetwork, hasFilesystem bool) (info.ContainerSpec, error)
func ListContainers ¶ added in v0.23.1
func ListDirectories ¶
func ListDirectories(dirpath string, parent string, recursive bool, output map[string]struct{}) error
Lists all directories under "path" and outputs the results as children of "parent".
func MakeCgroupPaths ¶
Types ¶
type ContainerHints ¶ added in v0.37.0
type ContainerHints struct {
AllHosts []containerHint `json:"all_hosts,omitempty"`
}
func GetContainerHintsFromFile ¶
func GetContainerHintsFromFile(containerHintsFile string) (ContainerHints, error)
type DeviceNamer ¶ added in v0.26.0
type DeviceNamer interface {
// DeviceName returns the name of the device by its major and minor ids, or false if no
// such device is recognized.
DeviceName(major, minor uint64) (string, bool)
}
DeviceNamer returns string names for devices by their major and minor id.
type InotifyWatcher ¶
type InotifyWatcher struct {
// contains filtered or unexported fields
}
Watcher for container-related inotify events in the cgroup hierarchy.
Implementation is thread-safe.
func NewInotifyWatcher ¶
func NewInotifyWatcher() (*InotifyWatcher, error)
func (*InotifyWatcher) AddWatch ¶
func (iw *InotifyWatcher) AddWatch(containerName, dir string) (bool, error)
Add a watch to the specified directory. Returns if the container was already being watched.
func (*InotifyWatcher) Error ¶
func (iw *InotifyWatcher) Error() chan error
Errors are returned on this channel.
func (*InotifyWatcher) Event ¶
func (iw *InotifyWatcher) Event() chan *inotify.Event
Events are returned on this channel.
func (*InotifyWatcher) GetWatches ¶
func (iw *InotifyWatcher) GetWatches() map[string][]string
Returns a map of containers to the cgroup paths being watched.
func (*InotifyWatcher) RemoveWatch ¶
func (iw *InotifyWatcher) RemoveWatch(containerName, dir string) (bool, error)
Remove watch from the specified directory. Returns if this was the last watch on the specified container.
type MachineInfoNamer ¶ added in v0.26.0
type MachineInfoNamer info.MachineInfo
func (*MachineInfoNamer) DeviceName ¶ added in v0.26.0
