AWS Elastic Container Registry — 101
In this post, I am going to give a quick overview of AWS ECR and help you understand its core features, benefits and functions.
A container registry is a collection of image repositories which are used to store and access container images. It plays crucial role in the container based application development.
Developers can store the container images in the registry and share it with other teams or developers. During the development lifecycle, of your containerized application, you can pull the image at any stage, and use it for development, testing or the launch of your application.
Docker Hub is one of the first and most popular container registries. Most of the cloud platforms offer their own container registries. AWS ECR is the container registry offered by AWS — Amazon Web Services.
