Docker image assets deployed to ECR

Project description

AWS CDK Docker Image Assets

---

Stability: Experimental

This is a developer preview (public beta) module. Releases might lack important features and might have future breaking changes.

This API is still under active development and subject to non-backward compatible changes or removal in any future version. Use of the API is not recommended in production environments. Experimental APIs are not subject to the Semantic Versioning model.


This module allows bundling Docker images as assets.

Images are built from a local Docker context directory (with a Dockerfile), uploaded to ECR by the CDK toolkit and/or your app's CI-CD pipeline, and can be naturally referenced in your CDK app.

# Example automatically generated. See https://github.com/aws/jsii/issues/826
from aws_cdk.aws_ecr_assets import DockerImageAsset

asset = DockerImageAsset(self, "MyBuildImage",
    directory=path.join(__dirname, "my-image")
)

The directory my-image must include a Dockerfile.

This will instruct the toolkit to build a Docker image from my-image, push it to an AWS ECR repository and wire the name of the repository as CloudFormation parameters to your stack.

Use asset.imageUri to reference the image (it includes both the ECR image URL and tag.

You can optionally pass build args to the docker build command by specifying the buildArgs property:

# Example automatically generated. See https://github.com/aws/jsii/issues/826
asset = DockerImageAsset(self, "MyBuildImage",
    directory=path.join(__dirname, "my-image"),
    build_args={
        "HTTP_PROXY": "http://10.20.30.2:1234"
    }
)

You can optionally pass a target to the docker build command by specifying the target property:

# Example automatically generated. See https://github.com/aws/jsii/issues/826
asset = DockerImageAsset(self, "MyBuildImage",
    directory=path.join(__dirname, "my-image"),
    target="a-target"
)

Pull Permissions

Depending on the consumer of your image asset, you will need to make sure the principal has permissions to pull the image.

In most cases, you should use the asset.repository.grantPull(principal) method. This will modify the IAM policy of the principal to allow it to pull images from this repository.

If the pulling principal is not in the same account or is an AWS service that doesn't assume a role in your account (e.g. AWS CodeBuild), pull permissions must be granted on the resource policy (and not on the principal's policy). To do that, you can use asset.repository.addToResourcePolicy(statement) to grant the desired principal the following permissions: "ecr:GetDownloadUrlForLayer", "ecr:BatchGetImage" and "ecr:BatchCheckLayerAvailability".
