Types ¶
type Attach ¶
Attach allows callers to reattach to running tasks
There should only be one reader for a task's IO set because fifo's can only be read from one reader or the output will be sent only to the first reads
type Config ¶
type Config struct {
// Terminal is true if one has been allocated
Terminal bool
// Stdin path
Stdin string
// Stdout path
Stdout string
// Stderr path
Stderr string
}
Config holds the io configurations.
type Creation ¶
Creation creates new IO sets for a task
type DirectIO ¶
type DirectIO struct {
Stdin io.WriteCloser
Stdout io.ReadCloser
Stderr io.ReadCloser
// contains filtered or unexported fields
}
DirectIO allows task IO to be handled externally by the caller
func NewDirectIO ¶
NewDirectIO returns an IO implementation that exposes the pipes directly
func (*DirectIO) Cancel ¶
func (f *DirectIO) Cancel()
Cancel stops any IO copy operations
Not applicable for DirectIO
type FIFOSet ¶
type FIFOSet struct {
// Dir is the directory holding the task fifos
Dir string
// In, Out, and Err fifo paths
In, Out, Err string
// Terminal returns true if a terminal is being used for the task
Terminal bool
}
FIFOSet is a set of fifos for use with tasks
type IO ¶
type IO interface {
// Config returns the IO configuration.
Config() Config
// Cancel aborts all current io operations
Cancel()
// Wait blocks until all io copy operations have completed
Wait()
// Close cleans up all open io resources
Close() error
}
IO holds the io information for a task or process
func Stdio ¶
Stdio returns an IO set to be used for a task that outputs the container's IO as the current processes Stdio
func StdioTerminal ¶
StdioTerminal will setup the IO for the task to use a terminal
