Azure Container Registry is a private container registry where you can upload and manage your Docker and Open Container Initiative (OCI) images. At the time of writing, the cost of the basic ACR tier including 10GiB storage is 5$ per month.
Prerequisites
- Azure subscription
- Azure CLI
Create an Azure Container Registry
Step 1. Open Terminal and login to the Azure Portal:
az login
Step 2. Create a resource group:
az group create --name "rg-container-registry-test-001" --location westeurope
Step 3. Create a container registry in the resource group that we’ve just created:
az acr create --resource-group "rg-container-registry-test-001" --name "acrdevcoopstest001" --location westeurope --sku Basic --admin-enabled true
Step 4. Login to the Azure Container Registry:
az acr login --name "acrdevcoopstest001"
It should display message: Login Succeeded
Step 5. The Docker Image needs to be tagged with the ACR’s loginServer name, so let’s query it:
az acr list --resource-group "rg-container-registry-test-001" --query "[].{acrLoginServer:loginServer}" --output table
Output:
AcrLoginServer
-----------------------------
acrdevcoopstest001.azurecr.io
Step 6. Now, tag your Docker Image:
docker tag mytestimage acrdevcoopstest001.azurecr.io/mytestimage
Step 7. Push Docker Image to Azure Container Registry:
docker push acrdevcoopstest001.azurecr.io/mytestimage
Step 8. List Docker Images in the registry:
az acr list --resource-group "rg-container-registry-test-001" --output table
Output:
| NAME | RESOURCE GROUP | LOCATION | SKU | LOGIN SERVER | CREATION DATE | ADMIN ENABLED |
| ------------------ | ------------------------------ | -------- | ----- | ----------------------------- | -------------------- | ------------- |
| acrdevcoopstest001 | rg-container-registry-test-001 | westeurope | Basic | acrdevcoopstest001.azurecr.io | 2021-03-07T15:11:37Z | True |
Cleanup
Step 9. Delete the resource group:
az group delete --name "rg-container-registry-test-001"
Conclusion
If you are working with container services on the Azure Cloud, then Azure Container Registry is the perfect solution for storing and managing container images.
