ECR provides a simple and scalable way to manage container images throughout their lifecycle,

The `EcrAsyncClient` interface in the AWS SDK for Java 2.x 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.

The Amazon Elastic Container Registry (ECR) is a fully-managed Docker container registry
service provided by AWS. It allows developers and organizations to securely

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

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

**Contoh 1: Untuk membuat repositori**
`create-repository`Contoh berikut membuat repositori di dalam namespace yang ditentukan dalam registri default untuk akun.
```
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"

}
```
Untuk informasi selengkapnya, lihat [Membuat Repositori](https://docs.aws.amazon.com/AmazonECR/latest/userguide/repository-create.html) di Panduan Pengguna *Amazon ECR*.
**Contoh 2: Untuk membuat repositori yang dikonfigurasi dengan immutabilitas tag gambar**
`create-repository`Contoh berikut membuat repositori dikonfigurasi untuk kekekalan tag dalam registri default untuk akun.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-tag-mutability IMMUTABLE
```
Output:
```

**Contoh 3: Untuk membuat repositori yang dikonfigurasi dengan konfigurasi pemindaian**
`create-repository`Contoh berikut membuat repositori yang dikonfigurasi untuk melakukan pemindaian kerentanan pada push gambar di registri default untuk akun.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-scanning-configuration scanOnPush=true

# Gunakan `StartLifecyclePolicyPreview` dengan AWS SDK atau CLI
Contoh kode berikut menunjukkan cara menggunakan`StartLifecyclePolicyPreview`.
Contoh tindakan adalah kutipan kode dari program yang lebih besar dan harus dijalankan dalam konteks. Anda dapat melihat tindakan ini dalam konteks dalam contoh kode berikut:
+ [Pelajari dasar-dasarnya](ecr_example_ecr_Scenario_RepositoryManagement_section.md)
------
#### [ CLI ]
**AWS CLI**
**Untuk membuat pratinjau kebijakan siklus hidup**
`start-lifecycle-policy-preview`Contoh berikut membuat pratinjau kebijakan siklus hidup yang ditentukan oleh file JSON untuk repositori tertentu.
```
aws ecr start-lifecycle-policy-preview \
--repository-name "project-a/amazon-ecs-sample" \
--lifecycle-policy-text "file://policy.json"
```
Isi dari `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",
