Creating a Parameter

Scenarios

You can create parameters to save data, such as accounts, keys, and common text data, which can be referenced by scripts and jobs. You can manage text parameters and encrypted data throughout the lifecycle.

Precautions

Parameter policies may delete parameters. Exercise caution when configuring parameter policies.
