Hi Shobith Shetty | IT Infra | ETPL,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
The error message you received indicates that authentication is required to access the Azure Container Registry (ACR) where your image is hosted.
To resolve this issue, please follow these steps:
You need to authenticate your Docker client to the Azure Container Registry.
Make sure that your Azure account has the necessary permissions to pull images from the ACR. You may need to be assigned a role such as "AcrPull" or "Owner" on the Azure Container Registry.
After successfully logging in, try running the Docker pull command again.
For more details, please refer to the below documentation:
