The Amazon Elastic Container Registry (ECR) is a fully-managed Docker container registry
service provided by AWS. It allows developers and organizations to securely
store, manage, and deploy Docker container images.
ECR provides a simple and scalable way to manage container images throughout their lifecycle,
from building and testing to production deployment.
The `EcrClient` service client that is part of the AWS SDK for Kotlin provides a set of methods to
programmatically interact with the Amazon ECR service. This allows developers to
automate the storage, retrieval, and management of container images as part of their application
deployment pipelines. With ECR, teams can focus on building and deploying their
applications without having to worry about the underlying infrastructure required to
host and manage a container registry.
This scenario walks you through how to perform key operations for this service.

The Amazon Elastic Container Registry (ECR) is a fully-managed Docker container registry

ECR provides a simple and scalable way to manage container images throughout their lifecycle,
from building and testing to production deployment.
The `ECRWrapper' class is a wrapper for the Boto3 'ecr' client. The 'ecr' client provides a set of methods to
programmatically interact with the Amazon ECR service. This allows developers to
automate the storage, retrieval, and management of container images as part of their application
deployment pipelines. With ECR, teams can focus on building and deploying their
applications without having to worry about the underlying infrastructure required to

------
#### [ CLI ]
**AWS CLI**
**Esempio 1: come creare un repository.**
L’esempio `create-repository` seguente crea un repository all’interno del namespace specificato nel registro predefinito per un account.
```
aws ecr create-repository \
--repository-name project-a/sample-repo
```
Output:
```
{
"repository": {
"registryId": "123456789012",
"repositoryName": "project-a/sample-repo",
"repositoryArn": "arn:aws:ecr:us-west-2:123456789012:repository/project-a/sample-repo"
}
}
```
Per ulteriori informazioni, consulta [Creazione di un repository](https://docs.aws.amazon.com/AmazonECR/latest/userguide/repository-create.html) nella *Guida per l’utente di Amazon ECR*.
**Esempio 2: come creare un repository configurato con l’immutabilità dei tag delle immagini**
L’esempio `create-repository` seguente crea un repository configurato per l’immutabilità dei tag nel registro predefinito per un account.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-tag-mutability IMMUTABLE
```
Output:
```
{
"repository": {
"registryId": "123456789012",
"repositoryName": "project-a/sample-repo",
"repositoryArn": "arn:aws:ecr:us-west-2:123456789012:repository/project-a/sample-repo",
"imageTagMutability": "IMMUTABLE"
}
}
```
Per ulteriori informazioni, consulta [Mutabilità del tag immagine](https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-tag-mutability.html) nella *Guida per l’utente di Amazon ECR*.
**Esempio 3: come creare un repository configurato con una configurazione di scansione**
L’esempio `create-repository` seguente crea un repository configurato per l’esecuzione di una scansione delle vulnerabilità all’esecuzione del push delle immagini nel registro predefinito per un account.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-scanning-configuration scanOnPush=true
```
Output:
```
{
"repository": {
"registryId": "123456789012",
"repositoryName": "project-a/sample-repo",
"repositoryArn": "arn:aws:ecr:us-west-2:123456789012:repository/project-a/sample-repo",
"imageScanningConfiguration": {
"scanOnPush": true
}
}
}

# Utilizzo `StartLifecyclePolicyPreview` con un AWS SDK o una CLI
Gli esempi di codice seguenti mostrano come utilizzare `StartLifecyclePolicyPreview`.
Gli esempi di operazioni sono estratti di codice da programmi più grandi e devono essere eseguiti nel contesto. È possibile visualizzare questa operazione nel contesto nel seguente esempio di codice:

#### [ CLI ]
**AWS CLI**
**Come creare un’anteprima di una policy del ciclo di vita**
L’esempio `start-lifecycle-policy-preview` seguente crea un’anteprima della policy del ciclo di vita definita in un file JSON per il repository specificato.
```
aws ecr start-lifecycle-policy-preview \
--repository-name "project-a/amazon-ecs-sample" \
--lifecycle-policy-text "file://policy.json"
```
Contenuto di `policy.json`:
```
{
"rules": [
{
"rulePriority": 1,
"description": "Expire images older than 14 days",
"selection": {
"tagStatus": "untagged",
"countType": "sinceImagePushed",
"countUnit": "days",
"countNumber": 14
},
"action": {
"type": "expire"
}
}
]
}
```
Output:
```
{
"registryId": "012345678910",
"repositoryName": "project-a/amazon-ecs-sample",
"lifecyclePolicyText": "{\n \"rules\": [\n {\n \"rulePriority\": 1,\n \"description\": \"Expire images older than 14 days\",\n \"selection\": {\n \"tagStatus\": \"untagged\",\n \"countType\": \"sinceImagePushed\",\n \"countUnit\": \"days\",\n \"countNumber\": 14\n },\n \"action\": {\n \"type\": \"expire\"\n }\n }\n ]\n}\n",
