What I want to do

I want to use Ratel to change schema

What I did

I use docker run a alpha and a zero node,then I entry the alpha with

docker exec -it 3d54781ed66b bash

Next，I use

dgraph alpha --security whitelist=172.0.0.1

or

dgraph alpha --security whitelist=0.0.0.0/0

but I get the same error

2023/06/08 08:40:28 Cannot acquire directory lock on "p".  Another process is using this Badger database. error: resource temporarily unavailable

How are you spinning up your cluster? I’m guessing you are entering a container that is already running the alpha server, so it is complaining that is cannot acquire a lock on the p directory (because the server is already using this directory).

Here is a sample docker compose file to set up the cluster. If you want to add a whitelist you can add the --security flag to the alpha initialization command.

yes ，you’re right .I 'm runing a alpha instance .but if I don’t run it ,I could not use the cLI,such as set the whitelist.

The whitelist is a flag param. Not a CLI command. All flags must be set and “boot” time.
