Question

I'm sorry for my english.

Hi, I'm starting to use emqx recently, is there a way to create default users via docker-compose env?

I searched the official guide and saw that the tool to do this should be

emqx_ctl admins add root public test

This command should create a new admin user with name "root", password "public" and tagged with "test" tag if I understand correctly.

Is there a way to do this via docker?

@Ciruxx Sorry to reply so late
We don't currently support creating admins via environment variables. If you need to, you can edit start.sh and build your own docker image.
