• AWS managed private Docker repository
• Pay for the storage you use to store docker images (no provisioning)
• Integrated with ECS & IAM for security
• Storage backed by S3
• Can upload Docker images on ECR manually or we can use a CICD service like CodeBuild

Pulling Images from ECR

• $(aws ecr get-login --no-include-email) - login to ECR
• docker pull <repo-url>/<image>
