aws.greengrass.labs.nodered.auth

This component is is used to define the authentication mechanism for the Node-RED components.

To specify a new username and password you need to create a secret in AWS Secrets Manager with name aws.greengrass.labs.nodered/<username> and with the password as plain text value.

You also need to add and configure aws.greengrass.SecretManager component to the deployment. The configuration specify the secret to synchronize and should include at least the ARN of the secret created for the username.

"cloudSecrets": [
    {
    "arn": "arn:aws:secretsmanager:eu-west-1:12345678901:secret:aws.greengrass.labs.nodered/<username>-XXXXXX"
    }
]

You must also configure the username to use in this component via the username configuration property.

If username is not equal to the value none this component gets the secret from SecretManager component, encodes an hash using bcrypt (see Generating a password hash), and creates a settings file fragment that is stored in the work folder.

The Node-RED components append this fragment (which in empty in case no authentication is configured) to the settings.js file.

If authentication is enabled, the admin API from Node-RED are protected. The flows and nodes components use this component to determine if there is a need to do an authenticated access.
