What are debug options for docker on Mac doing? How do I see more verbose logging of docker client?

Question

From the look of the doc, I was under the impression that

docker -D -l debug --debug pull ...

will print verbose logging of some kind. But that wasn't the case. Neither was the setting in advance setting:

Am I missing something? docker info does confirm I am in debug mode, though it doesn't say anything about logging location. Not sure if I am missing something here.

I'm on Mac

➜  ~ docker version

没关系，我发现源代码中几乎没有任何调试日志记录，对于这个拉取目标尤其如此： https : //github.com/docker/docker-ce/blob/master/components/cli/vendor/github.com /docker/docker/client/image_create.go
