# Exemplos de código para o Amazon ECR usando AWS SDKs
Os exemplos de código a seguir mostram como usar o Amazon Elastic Container Registry com um kit de desenvolvimento de AWS software (SDK).
As *noções básicas* são exemplos de código que mostram como realizar as operações essenciais em um serviço.
*Ações* são trechos de código de programas maiores e devem ser executadas em contexto. Embora as ações mostrem como chamar perfis de serviço individuais, você pode ver as ações no contexto em seus cenários relacionados.

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.\s
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.
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
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

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**
**Exemplo 1: para criar um repositório**
O exemplo `create-repository` a seguir cria um repositório dentro do namespace especificado no registro padrão de uma conta.
```
aws ecr create-repository \
--repository-name project-a/sample-repo
```
Saída:
```
{
"repository": {
"registryId": "123456789012",
"repositoryName": "project-a/sample-repo",
"repositoryArn": "arn:aws:ecr:us-west-2:123456789012:repository/project-a/sample-repo"
}
}
```
Para obter mais informações, consulte [Creating a repository](https://docs.aws.amazon.com/AmazonECR/latest/userguide/repository-create.html) no *Guia do usuário do Amazon ECR*.
**Exemplo 2: criar um repositório configurado com imutabilidade da tag de imagem**
O exemplo `create-repository` a seguir cria um repositório configurado para imutabilidade de tags no registro padrão de uma conta.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-tag-mutability IMMUTABLE
```
Saída:
```
{
"repository": {
"registryId": "123456789012",

```
Para obter mais informações, consulte [Mutabilidade da tag de imagem](https://docs.aws.amazon.com/AmazonECR/latest/userguide/image-tag-mutability.html) no *Guia do usuário do Amazon ECR*.
**Exemplo 3: criar um repositório configurado com uma configuração de digitalização**
O exemplo de `create-repository` a seguir cria um repositório configurado para realizar uma verificação de vulnerabilidade no envio de imagens por push no registro padrão de uma conta.
```
aws ecr create-repository \
--repository-name project-a/sample-repo \
--image-scanning-configuration scanOnPush=true
```
Saída:
```
