Containers
Azure Container Registry
Private registry for container images and artifacts.
Key points
- Stores versioned images for runtimes such as Azure Container Instances and Azure Container Apps to pull.
- Organizes images into repositories addressed by tags or digests.
- Runtimes need authenticated pull access and an allowed network path.
Best-known use cases
- Store internal images for ACI and Container Apps.
- Control image distribution under an Azure resource boundary.
What candidates often confuse it with
- ACR vs ACI: image storage and distribution vs container execution.
- Tag vs digest: mutable human-friendly reference vs immutable content reference.
Key takeaway
Use ACR to store and govern private images, then authorize the chosen runtime to pull them.
