#### [ CLI ]
**AWS CLI**
**Para descrever uma imagem em um repositório**
O exemplo de `describe-images` a seguir exibe os detalhes sobre uma imagem no repositório `cluster-autoscaler` com a tag `v1.13.6`.
```
aws ecr describe-images \
--repository-name cluster-autoscaler \
--image-ids imageTag=v1.13.6
```
Saída:
```
{
"imageDetails": [
{
"registryId": "012345678910",
"repositoryName": "cluster-autoscaler",
"imageDigest": "sha256:4a1c6567c38904384ebc64e35b7eeddd8451110c299e3368d2210066487d97e5",
"imageTags": [
"v1.13.6"
],
"imageSizeInBytes": 48318255,
"imagePushedAt": 1565128275.0
}
]
}
