What is Azure Container Registry (ACR)?

Azure Container Registry (ACR) is a managed, private Docker registry service for storing and managing container images and related artifacts. It is the Azure equivalent of Docker Hub but private to your organization. Key features: Geo-replication: replicate images across multiple regions for low-latency pulls. ACR Tasks: automatically build and push images when code is committed (cloud-native CI for containers). Security: integrates with Azure AD for RBAC, supports content trust (image signing), and scans images for vulnerabilities with Defender for Containers. Helm charts and OCI artifacts can also be stored. Integrates natively with AKS — AKS can pull images from ACR without managing credentials.
