## Examples
<a name="API_PutLifecyclePolicy_Examples"></a>

In the following example or examples, the Authorization header contents (`AUTHPARAMS`) must be replaced with an Amazon Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.amazonaws.cn/general/latest/gr/signature-version-4.html) in the * Amazon General Reference*.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the [Amazon Command Line Interface (Amazon CLI)](http://www.amazonaws.cn/cli/) or one of the [Amazon SDKs](http://www.amazonaws.cn/tools/) to make requests to Amazon, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

### Example
<a name="API_PutLifecyclePolicy_Example_1"></a>

This example creates a lifecycle policy to expire images older than 14 days for a repository called `project-a/amazon-ecs-sample` in the default registry for an account.
