Windows requires that stderr is an empty string when running a container with TTY. In Containerd, pkg/cio/io.go#L298-L302, the Stderr is set to a value, e.g.

res = "binary:///C:/_xxx_/nerdctl.exe?_NERDCTL_INTERNAL_LOGGING=C%3A%5CProgramData%5Cnerdctl%5C052055e3"

which causes microsoft/hcsshim service_internal.go#L127 to fail to create a new task.

To address this issue related to nerdctl, we can refactor the TerminalLogURI() function. This will involve adding an optional parameter that specifies whether stderr should be set to an empty string when the terminal is used. This change will help avoid the "failed precondition" error when creating a new task on Windows.

Example:

func TerminalLogURI(uri *url.URL, setStderr ...bool) Creator {
	return func(_ string) (IO, error) {
		// Default value for Stderr is an ampty string
		stderr := ""
        
		if len(setStderr) > 0 && setStderr[0] {
			stderr = uri.String()
		}

		return &logURI{
			config: Config{
				Stdout:   uri.String(),
				Stderr:   stderr,
				Terminal: true,
			},
		}, nil
	}
}
