    Study Notes

    Azure Container Registry Tasks

    • Can be used to automate the build, push, and deployment of container images
    • Can automate the creation of container images in response to code commits
    • Can be configured to trigger builds on a schedule, on code changes, or on a timer
    • Can automate the creation of multi-architecture images

    Azure Container Registry

    • Can store Docker container images, as well as other types of images
    • Supports building and running applications at scale
    • Can be used by developers to manage and store container images
    • Supports private link with private endpoints in Premium tier for enhanced security
    • Has service tiers that provide different levels of features and support
    • Basic tier is most suitable for lower usage scenarios
    • Standard tier is most suitable for high-volume scenarios and provides additional features such as geo-replication
    • Premium tier provides additional features such as zone redundancy and enhanced security

    Geo-Replication and Zone Redundancy

    • Geo-replication allows registry data to be stored in multiple regions for better performance and resiliency
    • Zone redundancy, a feature of Premium tier, uses Azure availability zones to replicate the registry to a minimum of three separate zones in each enabled region
    • Provides high availability and disaster recovery capabilities

    Image Security and Data Protection

    • Azure automatically encrypts images before storing them in the registry
    • Supports encryption-at-rest for all container images in the registry
    • Provides image data protection across all service tiers
    • Data is stored in regions that meet data residency and compliance requirements
    • Data is automatically replicated to a paired region in the same geography for resiliency

    Azure Container Registry Tasks Features

    • Supports multi-step tasks
    • Allows specifying the --platform tag for building multi-architecture images
    • Supports scheduling tasks on a timer
    • Tracks dependencies on base images
    • Automatically builds application images when the base image is updated
    • Supports quick tasks for rapid image creation
    • Has a source code context associated with each task

    Docker and Dockerfiles
