Question

Answer 1

If you need to consume a container image as part of your CI/CD pipeline, you can achieve it using Resources: containers. A container resource can be a public or private Docker Registry, or Azure Container Registry.

resources:          # types: pipelines | repositories | containers | builds | packages
  containers:
  - container: string # identifier for the container resource      
    type: string # type of the registry like ACR, GCR etc. 
    azureSubscription: string # Azure subscription (ARM service connection) for container registry;
    resourceGroup: string # resource group for your ACR
    registry: string # registry for container images
    repository: string # name of the container image repository in ACR
    trigger: # Triggers are not enabled by default and need to be set explicitly
      tags:
        include: [ string ]  # image tags to consider the trigger events, optional; defaults to any new tag
        exclude: [ string ]  # image tags on discard the trigger events, optional; defaults to none

For example:

resources:         
  containers:
  - container: petStore      
    type: ACR  
    azureSubscription: ContosoARMConnection
    resourceGroup: ContosoGroup
    registry: petStoreRegistry
    repository: myPets
    trigger: 
      tags:
        include: 
        - production* 

or

resources:
  containers:
  - container: mycontainer # name of the container (Alias) 
    type: ACR # type of registry
    azureSubscription: arm-connection # name of the ARM service connection
    resourceGroup: rg-storage-eastus # Azure resource group with the container
    registry: mycontainerregistry # Azure container registry name
    repository: hello-world # name of the of container image collection
    trigger:
      tags:
      - latest # tag for the container image to use
