Now it worked, running the command 10 hours later is the solution 
Maybe yesterday there were some resources not been downloaded in docker due to the great firewall of CHINA. EVIL…
====above is update========
I’m struggling with this, and sadly, I don’t know how to resolve it. The platform works fine, so I think there’s no problem with mysql. But why it can’t be connected when creating superuser.
And what should I supposed to do or search or learn looking at all this prompt? Just have no clue. Thanks in advance.
