secretArn
The ARN of the secret that enables access to the DB cluster. Enter the database user name and password for the credentials in the secret.
For information about creating the secret, see Create a database secret.
When you use the CLI on Linux to reference a secret created in the RDS console, the ARN might include special characters like rds!cluster. If you enclose the ARN in double quotes, the ! character might trigger a shell expansion error, such as -bash: !cluster: event not found. To avoid this, escape the exclamation mark (\!) in the ARN or enclose the entire ARN in single quotes (') instead of double quotes.
Alternatively, disable shell history expansion by running set +H before you execute the command.
