# Use `GetRepositoryPolicy` with an AWS SDK or CLI
The following code examples show how to use `GetRepositoryPolicy`.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

------
#### [ CLI ]
**AWS CLI**
**To retrieve the repository policy for a repository**
The following `get-repository-policy` example displays details about the repository policy for the `cluster-autoscaler` repository.
```
aws ecr get-repository-policy \
--repository-name cluster-autoscaler
```
Output:
```
{
"registryId": "012345678910",
"repositoryName": "cluster-autoscaler",
"policyText": "{\n \"Version\" : \"2008-10-17\",\n \"Statement\" : [ {\n \"Sid\" : \"allow public pull\",\n \"Effect\" : \"Allow\",\n \"Principal\" : \"*\",\n \"Action\" : [ \"ecr:BatchCheckLayerAvailability\", \"ecr:BatchGetImage\", \"ecr:GetDownloadUrlForLayer\" ]\n } ]\n}"
}
