• Constants
• func Run(ctx context.Context, hook *rspec.Hook, state []byte, stdout io.Writer, ...) (hookErr, err error)
• func RuntimeConfigFilter(ctx context.Context, hooks []spec.Hook, config *spec.Spec, ...) (hookErr, err error)

Constants

const DefaultPostKillTimeout = time.Duration(10) * time.Second

DefaultPostKillTimeout is the recommended default post-kill timeout.

Functions

func Run

func Run(ctx context.Context, hook *rspec.Hook, state []byte, stdout io.Writer, stderr io.Writer, postKillTimeout time.Duration) (hookErr, err error)

Run executes the hook and waits for it to complete or for the context or hook-specified timeout to expire.

func RuntimeConfigFilter

func RuntimeConfigFilter(ctx context.Context, hooks []spec.Hook, config *spec.Spec, postKillTimeout time.Duration) (hookErr, err error)

RuntimeConfigFilter calls a series of hooks. But instead of passing container state on their standard input, RuntimeConfigFilter passes the proposed runtime configuration (and reads back a possibly-altered form from their standard output).
