Azure Container Registry CLI

Manage Azure Container Registry (ACR) resources using the az acr command group of the Azure CLI.

CLI: az acr ships with core Azure CLI — no extension required (the acrtransfer extension is only needed for export/import pipelines).

Prerequisites

# Install Azure CLI
brew install azure-cli  # macOS
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash  # Linux
winget install Microsoft.AzureCLI  # Windows

# Sign in and select subscription
az login
az account set --subscription {subscription-id}

Quick Start

# Create a registry (SKU: Basic | Standard | Premium)
az acr create --resource-group {rg} --name {registry} --sku Standard

# Authenticate Docker/Podman against the registry
az acr login --name {registry}

# Build and push in the cloud — no local Docker needed
az acr build --registry {registry} --image app:v1 .

# Copy an image from another registry without pull/push
az acr import --name {registry} --source mcr.microsoft.com/hello-world:latest

# List repositories and tags
az acr repository list --name {registry} --output table
az acr repository show-tags --name {registry} --repository app --orderby time_desc

# Diagnose registry connectivity and configuration
az acr check-health --name {registry} --yes

Key Principles

• Prefer az acr build / ACR Tasks over local docker build + docker push: builds run in Azure, work without a local daemon, and integrate with triggers.
• Prefer az acr import to move images between registries: it is server-side, faster, and requires no local storage.
• Never enable the admin user for production — use Microsoft Entra identities (RBAC roles AcrPull/AcrPush, or Container Registry Repository Reader/Writer on ABAC-enabled registries), repository-scoped tokens, or managed identities.
• Premium-only features: geo-replication, private endpoints, retention policies, connected registries, agent pools. (Repository-scoped tokens work in all tiers; zone redundancy is automatic in all tiers in supported regions.)
