#### [ CLI ]

**AWS CLI**  
**取得預設登錄檔的授權字符**  
下列 `get-authorization-token` 範例命令會取得預設登錄檔的授權字符。  

```
aws ecr get-authorization-token
```
輸出：  

```
{
    "authorizationData": [
        {
            "authorizationToken": "QVdTOkN...",
            "expiresAt": 1448875853.241,
            "proxyEndpoint": "https://123456789012.dkr.ecr.us-west-2.amazonaws.com"
        }
    ]
}
```
