Amazon Elastic Container Registry (ECR) is a fully managed Docker container registry that makes it easy to store, manage, and deploy Docker container images.
Amazon ECR allows you to push Docker container images to a repository and then pull those images to deploy containers on Amazon ECS, Kubernetes, or other container orchestrators.
Key features of Amazon ECR include secure and private Docker image storage, integration with AWS Identity and Access Management (IAM), lifecycle policies, and image vulnerability scanning.
A Docker container image is a lightweight, standalone, and executable software package that contains everything needed to run a piece of software, including code, runtime, libraries, and settings.
You can use the docker push command to push Docker images to Amazon ECR repositories after authenticating with your AWS credentials.
You can use the docker pull command to pull Docker images from Amazon ECR repositories after authenticating with your AWS credentials.
Amazon ECR lifecycle policies allow you to define rules that automatically clean up and manage images based on conditions like image age, count, and usage.
Amazon ECR supports image vulnerability scanning by integrating with Amazon ECR Public and AWS Security Hub to provide insights into the security posture of your container images.
Amazon ECR repositories are private by default and can be accessed only by authorized users and roles. You can control access using IAM policies and resource-based policies.
Amazon ECR integrates seamlessly with Amazon ECS, allowing you to use your ECR repositories to store and manage container images for your ECS tasks and services.
ECR lifecycle policies are rules you define to manage the retention of images in your repositories. They help keep your image repositories organized and free up storage space.
Yes, you can use Amazon ECR in multi-region deployments by replicating images across different regions and using cross-region replication.
Amazon ECR Public is a feature that allows you to store and share publicly accessible container images. It's useful for distributing open-source software or other public content.
You can improve image build and deployment speed by using Amazon ECR's image layer caching and pulling pre-built base images from the registry.
The Amazon ECR Docker Credential Helper is a tool that simplifies authentication to Amazon ECR repositories, allowing Docker to authenticate with ECR using IAM credentials.
Amazon ECR supports image versioning by allowing you to tag images with different version labels. This helps in maintaining different versions of the same image.
Yes, you can use Amazon ECR with Kubernetes by configuring the necessary authentication and pulling container images from ECR repositories when deploying pods.
Amazon ECR provides cross-region replication to replicate images to different AWS regions, improving availability and reducing latency for users in different regions.
Amazon ECR charges based on the amount of data stored in your repositories and the data transferred out to other AWS regions or services.
Amazon ECR provides high availability by replicating images across multiple Availability Zones within a region, ensuring durability and availability of your container images.
