Functions ¶
func AtomicCopy ¶
AtomicCopy copies file by reading the file then writing atomically into the target directory
func AtomicWrite ¶
AtomicWrite atomically by writing to a temporary file in the same directory then renaming
func CreateFileWatcher ¶
func CreateFileWatcher(dirs ...string) (watcher *fsnotify.Watcher, fileModified chan bool, errChan chan error, err error)
CreateFileWatcher creates a file watcher that watches for any changes to the directory
func GetPlugin ¶
GetPlugin given the raw plugin interface, return the plugin asserted as a map[string]interface{}
func GetPlugins ¶
GetPlugins given an unmarshalled CNI config JSON map, return the plugin list asserted as a []interface{}
func IP2Pointer ¶
IP2Pointer returns the pointer of a ip string
func IsDirWriteable ¶
IsDirWriteable checks if dir is writable by writing and removing a file to dir. It returns nil if dir is writable. Inspired by etcd fileutil.
func MarshalCNIConfig ¶
MarshalCNIConfig marshal the CNI config map and append a new line
