Why my Dockerfile causes error at Docker Hub?

dockerhub

(Kiwamu Okabe) #1

I write following Dockerfile:

And autobuild it on Docker Hub:

https://hub.docker.com/r/masterq/docker4fdb/builds/bcuvzfebhz4nzu7xkdvpjie/

But it causes an error report “Unexpected error”. However I can pull the image:

$ docker pull masterq/docker4fdb

Why does Docker Hub maintain my Dockerfile as error?

Best regards,
