How to push an image to LocalStack ECR using Python?

Question

Pulumi · Accepted Answer

You can use the Pulumi AWS SDK to create an Elastic Container Registry (ECR) repository and push an image to it. However, please note that Pulumi doesn't inherently support pushing the Docker images to the created ECR repository. For this action, you may want to use Docker CLI or AWS CLI commands.

The following is a Python program that creates an ECR repository using Pulumi with Python.

Please note, this code is not designed to interact with LocalStack as Pulumi does not directly support LocalStack. For Pulumi, you would have to configure your AWS provider with access to your real AWS account.

import pulumi
import pulumi_aws as aws

# Create ECR repository
ecr_repo = aws.ecr.Repository("example-repo")

# Export the repository URL
pulumi.export("repository_url", ecr_repo.repository_url)

Executing this sample will create an ECR repository in your configured AWS account.

After that, for pushing an image to the created ECR repository, you would normally use Docker CLI or AWS CLI. Below is an example of how you could do it:

# Log in to the ECR repository using Docker
$(aws ecr get-login --region <region> --no-include-email)

# Tag the image 
docker tag <image> <repository_url>:<tag>

# Push the image to the ECR repository 
docker push <repository_url>:<tag>

In the above shell commands, replace <region> with your AWS region, <image> with your image name, <repository_url> with the URL of the ECR repository (the output of the Pulumi program), and <tag> with your desired tag.

For using LocalStack ECR with AWS CLI or SDKs, you'd have to point your AWS endpoint configuration to LocalStack endpoint, but right now, Pulumi does not support LocalStack out of the box. For Pulumi, you would configure your AWS provider with access to a real AWS account.
