Static User Provider

GreptimeDB offers a simple built-in mechanism for authentication, allowing users to configure either a fixed account for convenient usage or an account file for multiple user accounts. By passing in a file, GreptimeDB loads all users listed within it.

Standalone Mode

GreptimeDB reads the user and password on each line using = as a separator, just like a command-line config. For example, create a file with the following content:

greptime_user=greptime_pwd
alice=aaa
bob=bbb

then start server with --user-provider parameter:

./greptime standalone start --user-provider=static_user_provider:file:<path_to_file>

Now, user alice with password aaa and user bob with password bbb are loaded into GreptimeDB's memory. You can create a connection to GreptimeDB using these user accounts.

Note: The content of the file is loaded into the database while starting up. Modifying or appending the file won't take effect while the database is up and running.

Kubernetes Cluster

You can configure the authentication users in the values.yaml file. For more details, please refer to the Helm Chart Configuration.
