您可以：

• 创建服务主体

# Create a service principal with required parameter
az ad sp create-for-rbac --scopes /subscriptions/mySubscriptionID

• 为注册表

#!/bin/bash
# Modify for your environment. The ACR_NAME is the name of your Azure Container
# Registry, and the SERVICE_PRINCIPAL_ID is the service principal's 'appId' or
# one of its 'servicePrincipalNames' values.
ACR_NAME=$containerRegistry
SERVICE_PRINCIPAL_ID=$servicePrincipal

# Populate value required for subsequent command args
ACR_REGISTRY_ID=$(az acr show --name $ACR_NAME --query id --output tsv)

# Assign the desired role to the service principal. Modify the '--role' argument
# value as desired:
# acrpull:     pull only
# acrpush:     push and pull
# owner:       push, pull, and assign roles
az role assignment create --assignee $SERVICE_PRINCIPAL_ID --scope 
$ACR_REGISTRY_ID --role acrpull

添加此主体的ACR Pull权限

• 然后使用此主体登录

az login --service-principal -u <app-id> -p <password-or-cert> --tenant <tenant>

通过这种方式，您可以避免交互式登录，并且应该能够在cron中运行它。
