Types ¶

type NsenterWriter ¶

type NsenterWriter struct {
}

Alternative implementation of Writer interface that allows writing data to file using nsenter command. If a program (e.g. kubelet) runs in a container it may want to write data to a mounted device. Since in Docker, mount propagation mode is set to private, it will not see the mounted device in its own namespace. To work around this limitaion one has to first enter hosts namespace (by using 'nsenter') and only then write data.

func (*NsenterWriter) WriteFile ¶

func (writer *NsenterWriter) WriteFile(filename string, data []byte, perm os.FileMode) error

type StdWriter ¶

type StdWriter struct {
}

StdWriter implements Writer interface and uses standard libraries for writing data to files.

func (*StdWriter) WriteFile ¶

func (writer *StdWriter) WriteFile(filename string, data []byte, perm os.FileMode) error

type Writer ¶

type Writer interface {
	WriteFile(filename string, data []byte, perm os.FileMode) error
}

Writer is an interface which allows to write data to a file.
