What is Azure Container Registry: Overview and Usage

Azure Container Registry is a private cloud service to store and manage container images securely. It lets you keep your Docker containers close to your Azure apps for easy deployment and scaling.

⚙️

How It Works

Think of Azure Container Registry like a private warehouse for your container images. Instead of storing your containers on your local computer or a public place, you keep them in this secure cloud storage. When you want to run your app, you pull the container image from this warehouse.

This service works closely with Azure services like Azure Kubernetes Service or Azure App Service. It helps your apps get the right container images quickly and safely. You can control who can see or use your containers, making sure only your team or systems have access.

💻

Example

This example shows how to create an Azure Container Registry using Azure CLI and push a Docker image to it.

bash

az acr create --resource-group myResourceGroup --name myContainerRegistry --sku Basic

docker login mycontainerregistry.azurecr.io

docker tag myapp:latest mycontainerregistry.azurecr.io/myapp:latest

docker push mycontainerregistry.azurecr.io/myapp:latest

Output

WARNING: Using 'Basic' SKU creates a registry with limited features. Login Succeeded The push refers to repository [mycontainerregistry.azurecr.io/myapp] ... latest: digest: sha256:abc123 size: 1234

🎯
