Using container images with Lambda - AWS Lambda

Using container images with Lambda

You can package your code and dependencies as a container image using tools such as the Docker command line interface (CLI). You can then upload the image to your container registry hosted on Amazon Elastic Container Registry (Amazon ECR).

AWS provides a set of open-source base images that you can use to build the container image for your function code. You can also use alternative base images from other container registries. AWS also provides an open-source runtime client that you add to your alternative base image to make it compatible with the Lambda service.

Additionally, AWS provides a runtime interface emulator for you to test your functions locally using tools such as the Docker CLI.

Note

You create each container image to be compatible with one of the instruction set architectures that Lambda supports. Lambda provides base images for each of the instruction set architectures and Lambda also provides base images that support both architectures.

The image that you build for your function must target only one of the architectures.

There is no additional charge for packaging and deploying functions as container images. When a function deployed as a container image is invoked, you pay for invocation requests and execution duration. You do incur charges related to storing your container images in Amazon ECR.
