您可以定义容器资源并将trigger参数设置为true，如本文文档中所述。
来自文档：

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 aren't enabled by default and need to be set explicitly
      enabled: boolean # set to 'true' to trigger on all image tags if 'tags' is unset.
      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
