Container Registry in Cloud

In this article we will explore container registry in Cloud and its Implementation in popular clouds — AWS, Azure and GCP.

Software Development Life cycle

Build an application and check-in the code changes to Code Repository like GITHUB. Code Build is performed, and Container (Docker) Image is created and pushed to Container Registry. During application deployment in different environments (Development DEV, User Acceptance Testing UAT, Production PROD), same docker image can be pulled from Container Registry.

In Azure cloud, we have Azure Container Registry (ACR) which can store Docker images, Open Container Initiative (OCI) images, and all OCI artifacts. In AWS cloud, we have Elastic Container Registry (ECR) which can store Docker images, Open Container Initiative (OCI) images, and OCI compatible artifacts. In GCP cloud, we have Artifact Registry, which can be used to maintain build artifacts like both container images and language packages.

Docker hub is a common registry provided by Docker to store and manger our docker images. For more security and privacy, we use private registries hosted in cloud and on-premises.
