This post will describe the required steps to follow in order to pull container images from Azure Container Registry (ACR) using Managed identity attached to the instance.

Managed identity provides seamless authentication to Azure resources.

• Create ACR

• Create Azure VM with managed identity attached to it (System or User assigned)

• Add AcrPull role on the managed identity

• Install Az CLI on the VM. Follow the documentation here

Login to Az CLI using Managed Identity

az login --identity

Login to ACR

az acr login —name <registryName>

Pull image from the container

docker pull <registryName>.azurecr.io/imageName:tag
