A developer previously deployed an AWS Lambda function as a .zip package. The developer needs to deploy the Lambda function as a container.
A.
Create an Amazon ECR repository in the same AWS Region as the Lambda function. Package the Lambda function into a container image. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function configuration to specify the repository URI and container image tag.
B.
Create an AWS SAM template that defines the Lambda function and its resources as code. Include a container image in the template, and store the container image in an Amazon S3 bucket. Deploy the AWS SAM template. Specify the S3 bucket URI.
C.
Create an AWS CloudFormation template that defines the Lambda function and its resources as code. Include a container image in the template, and store the image in an Amazon S3 bucket. Deploy the CloudFormation template. Specify the S3 bucket URI.
D.
Create an Amazon ECR repository in the same AWS Region as the Lambda function. Build the image and upload it to the Amazon ECR repository. Update the existing Lambda function to use the new image by specifying the repository URI.
Why Option A is Correct:Converting a Lambda function to use a container image involves packaging the function code into a container image, storing the image in Amazon Elastic Container Registry (ECR), and updating the function to use the ECR repository URI.
Why Other Options are Incorrect:
Option B:SAM templates support container-based Lambda deployment, but storing the image in S3 is not applicable.
Option C:CloudFormation does not natively support specifying Lambda container images in S3.
Option D:While partially correct, it omits the need to specify the image tag for the deployment.
