Hi:
i don’t want to show my mysql userpasword in common.runtime.properties , i find the new version 0.10.0 has the Password Provider function, but no examples.

druid.metadata.storage.connector.password
The password provider or String password used to connect with.
none

Password Provider

Environment variable password provider provides password by looking at specified environment variable. Use this in order to avoid specifying password in runtime.properties file. e.g

   {
    "type": "environment",
    "variable": "METADATA_STORAGE_PASSWORD"
   }

The values are described below.

You need to first to include the following config in the runtime properties file

druid.metadata.storage.connector.password={ “type”: “environment”,“variable”: "METADATA_STORAGE_PASSWORD”}

Then make sure to export an environment variable called METADATA_STORAGE_PASSWORD in this example that has the password.

For instance you can add this to your start command:

export METADATA_STORAGE_PASSWORD=YOUR_PASSWORD; start_druid_command….
