What is an ECR repository?

The Amazon ECR is a fully managed Docker container offering provided by Amazon Web Services as it is prevalently called, abbreviated as AWS, which is a cloud computing subsidiary of Amazon. In turn, it becomes the hub where Docker image collections are located and maintained as well as allocated to containerized applications that are crucial in building applications.

In the container world, Docker images are the fundamental building block that captures an application and the dependencies to deliver the same across various environments including disparate infrastructures for seamless deployment. Nevertheless, these data containers will be stored in a central registry where the ECR temporaries will be added.

Distributing ECR containers ensures the availability of private; highly available, and secure repositories for Docker images. This provides the development teams and DevOps administrators with storage and version facilities of container images, which not only facilitates collaboration effectively among team members but also the smooth deployment of ongoing projects. Repositories of ECR may be differentiating for the libraries, each of which contains multiple Docker Images, designated by different tags (versions and configurations).

In a cloud computing and microservice world, we must concentrate on the involvement of the infrastructure resources properly. With Terraform, an open source IaC (infrastructure as code) tool that is widely used for provisioning and managing cloud resources across many cloud service providers such as AWS (Amazon Web Services), becoming the de-facto standard, it is not surprising that people have started noticing its advantages over other available options. Among the workable services of AWS is Amazon Elastic Container Registry (ECR) which is a well-managed Docker container registry that gives the chance to images to store, manage, and deploy.

Terraform replies to the difficulty of creating and handling ECR repositories by providing a hot approach to IT architecture preservation. In Terraform, you may define your desired state of an ECR repository and other associated resources in a software configuration file. Terraform will consequently handle the creation, updating, and maintenance procedures for your infrastructure.
