Azure Container Registry, Docker Hub, GitHub GHCR — store, scan, and distribute container images.
Five passes over the same idea, each from a different angle. Do them in order, or jump to whichever you need.
Container registries store and distribute Docker images. Key features: image tagging and versioning, vulnerability scanning, geo-replication, access control, and image signing. Azure Container Registry (ACR) integrates with AKS and Azure DevOps. Best practices: immutable tags, scanning policies, and retention rules.
