Functions ¶
func NewCRILogger ¶
func NewCRILogger(path string, stream StreamType) (io.WriteCloser, error)
NewCRILogger returns a write closer which redirect container log into log file, and decorate the log line into CRI defined format.
func NewDiscardLogger ¶
func NewDiscardLogger() io.WriteCloser
NewDiscardLogger creates logger which discards all the input.
Types ¶
type AttachOptions ¶
type AttachOptions struct {
Stdin io.Reader
Stdout io.WriteCloser
Stderr io.WriteCloser
Tty bool
StdinOnce bool
// CloseStdin is the function to close container stdin.
CloseStdin func() error
}
AttachOptions specifies how to attach to a container.
type ContainerIO ¶
type ContainerIO struct {
// contains filtered or unexported fields
}
ContainerIO holds the container io.
func NewContainerIO ¶
func NewContainerIO(id string, opts ...ContainerIOOpts) (_ *ContainerIO, err error)
NewContainerIO creates container io.
func (*ContainerIO) Attach ¶
func (c *ContainerIO) Attach(opts AttachOptions) error
Attach attaches container stdio. TODO(random-liu): Use pools.Copy in docker to reduce memory usage?
func (*ContainerIO) Pipe ¶
func (c *ContainerIO) Pipe()
Pipe creates container fifos and pipe container output to output stream.
type ContainerIOOpts ¶
type ContainerIOOpts func(*ContainerIO) error
ContainerIOOpts sets specific information to newly created ContainerIO.
func WithFIFOs ¶
func WithFIFOs(fifos *cio.FIFOSet) ContainerIOOpts
WithFIFOs specifies existing fifos for the container io.
func WithNewFIFOs ¶
func WithNewFIFOs(root string, tty, stdin bool) ContainerIOOpts
WithNewFIFOs creates new fifos for the container io.
func WithOutput ¶
func WithOutput(name string, stdout, stderr io.WriteCloser) ContainerIOOpts
WithOutput adds output stream to the container io.
type ExecIO ¶
type ExecIO struct {
// contains filtered or unexported fields
}
ExecIO holds the exec io.
func (*ExecIO) Attach ¶
func (e *ExecIO) Attach(opts AttachOptions) <-chan struct{}
Attach attaches exec stdio. The logic is similar with container io attach.
type StreamType ¶
type StreamType string
StreamType is the type of the stream, stdout/stderr.
const ( // Stdin stream type. Stdin StreamType = "stdin" // Stdout stream type. Stdout StreamType = StreamType(runtime.Stdout) // Stderr stream type. Stderr StreamType = StreamType(runtime.Stderr) )
